  • What is a custom collection?

    - by Win Coder
    A Group of objects. However i am having confusion in the following case. A sample class Class A { public string; } Class A_list { public A[] list; public A_list(A[] _list) { list = new A[_list.length]; for (int i = 0; i < _list.Length; i++) { list[i] = _list[i]; } } } static void Main(String[] args) { A[] names = new A[3] { new A("some"), new A("another"), new A("one"), }; A_list just_an_object = new A_list(names); } Which of the above is a custom collection the array or the object that holds array as a field or are both custom collections.

  • mySql table returning JSON that needs formatting for a iPhone UITableview

    - by Michael Robinson
    I have a php query the returns the following JSON format from a table. [{"memberid":"18", "useridFK":"30", "loginName":"Johnson", "name":"Frank", "age":"23", "place":"School", }, It needs the following format: [{"memberid":"18" { "useridFK":"30", "loginName":"Johnson", "name":"Frank", "age":"23", "place":"School",} }, I can figure out where/how to convert this, Where would I create the formatting following: (1) In the php return? (2) the JSON instructions for deserialization? or (3) Some kinb of Obj-C coding instruction? My end use is a simple Drill Down table using the NSObject, so when I select "memberid" row, I'll get the child/detail list on the next UITableview. My Data.plist will look like the following: Root: Dictionary V Rows: Array V Item 0: Dictionary Title: String 18 V Children Array V Item 0 Dictionary Title String 30 etc. Thanks in advance, this site rocks.

  • Adding objects to an NSMutableArray, order seems odd when parsing from an XML file

    - by diatrevolo
    Hello: I am parsing an XML file for two elements: "title" and "noType". Once these are parsed, I am adding them to an object called aMaster, an instance of my own Master class that contains NSString variables. I am then adding these instances to an NSMutableArray on a singleton, in order to call them elsewhere in the program. The problem is that when I call them, they don't seem to be on the same NSMutableArray index... each index contains either the title OR the noType element, when it should be both... can anyone see what I may be doing wrong? Below is the code for the parser. Thanks so much!! #import "XMLParser.h" #import "Values.h" #import "Listing.h" #import "Master.h" @implementation XMLParser @synthesize sharedSingleton, aMaster; - (XMLParser *) initXMLParser { [super init]; sharedSingleton = [Values sharedValues]; aMaster = [[Master init] alloc]; return self; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { aMaster = [[Master alloc] init]; //Extract the attribute here. if ([elementName isEqualToString:@"intro"]) { aMaster.intro = [attributeDict objectForKey:@"enabled"]; } else if ([elementName isEqualToString:@"item"]) { aMaster.item_type = [attributeDict objectForKey:@"type"]; //NSLog(@"Did find item with type %@", [attributeDict objectForKey:@"type"]); //NSLog(@"Reading id value :%@", aMaster.item_type); } else { //NSLog(@"No known elements"); } //NSLog(@"Processing Element: %@", elementName); //HERE } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue appendString:string];//[tempString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; CFStringTrimWhitespace((CFMutableStringRef)currentElementValue); } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { [sharedSingleton.master addObject:aMaster]; NSLog(@"Added %@ and %@ to the shared singleton", aMaster.title, aMaster.noType); //Only having one at a time added... don't know why [aMaster release]; aMaster = nil; } else if ([elementName isEqualToString:@"title"]) { [aMaster setValue:currentElementValue forKey:@"title"]; } else if ([elementName isEqualToString:@"noType"]) { [aMaster setValue:currentElementValue forKey:@"noType"]; //NSLog(@"%@ should load into the singleton", aMaster.noType); } NSLog(@"delimiter"); NSLog(@"%@ should load into the singleton", aMaster.title); NSLog(@"%@ should load into the singleton", aMaster.noType); [currentElementValue release]; currentElementValue = nil; } - (void) dealloc { [aMaster release]; [currentElementValue release]; [super dealloc]; } @end

  • Encrypt/Decrypt SQLite-database and use it "on the fly"

    - by Berschi
    Here's the thing: In my Qt4.6-Project, I use a SQLite-Database. This database shouldn't be unencrypted on my harddrive. So I want, that on every start of my program, the user gets asked to enter a password to decrypt the database. Of course the database never should appear "in clear" (not encrypted) on my harddrive. So is there any possibility to decrypt a SQLite-database "on the fly" and read and write data? What algorithm is here the best (maybe AES)? When it's not possible (or very slow), maybe it's better to encrypt every string in the database and decrypt the string when the password was right (so that a user could open the database, but has no clue what all the entrys could mean)?

  • How to convert a unicode charactor array back to unicode sequence in C++

    - by eddyxd
    My problem is how to convert a c/c++ string/chractor array to another string contain the unicode(UTF-16) escape sequence of original one for example, I want to find a function F(char *ch) could do following function. char a[10] = "\u5f53"; printf("a = %s\n",a); char b[10]; b = F(a); //<- F is the function I wanted printf("b = %s\n",b); -------- console will show ------- a = ? b = \u5f53 Anyone has any Idea@@?~ thanks!! ps: I tried to guess \u5f35 means the value store in a, but it is not indeed the value of a[0] = -79 , a[1] = 105 ... So I don't know how to convert it back to the sequence of unicode.... Please give me a hane~ : )

    I am importing data from excel(.xls) to SQL Server 2008 using SSIS. I have included IMEX=1 in the connection string of excel connection manager. But a column consists of a value as below: 4-Hour Engineer Dispatch ASPP Engr Dispatch 1: Up to 1 dispatch (8 hours) per year. Hours exceeding allocation billed @ 1.5x hourly rate w/ 8-hr min Engr Dispatch: 8-hrs to arrive on-site from Ciena's determination of need On-Site Engineer Dispatch - 8 Hour ASPP Engr Dispatch 8: Up to 8 dispatch (64 hours) per year.

So, the datatype of that column is taken as nvarchar(255) as default instead of ntext and so i am getting error. Anybody please help out... Thanks in advance...

  • Using Window Handle to disable Mouse clicks and Keyboard Inputs using P/Invoke

    - by srk
    I need to disable the Mouse Clicks, Mouse movement and Keyboard Inputs for a specific windows for a Kiosk application. Is it feasible using .NET ? I have removed the menu bar and title bar of a specific window, will that be a starting point to achieve the above requirement ? The code for removing the menu bar and title bar using window handle : #region Constants //Finds a window by class name [DllImport("USER32.DLL")] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Sets a window to be a child window of another window [DllImport("USER32.DLL")] public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //Sets window attributes [DllImport("USER32.DLL")] public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); //Gets window attributes [DllImport("USER32.DLL")] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); [DllImport("user32.dll")] static extern IntPtr GetMenu(IntPtr hWnd); [DllImport("user32.dll")] static extern int GetMenuItemCount(IntPtr hMenu); [DllImport("user32.dll")] static extern bool DrawMenuBar(IntPtr hWnd); [DllImport("user32.dll")] static extern bool RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags); //assorted constants needed public static uint MF_BYPOSITION = 0x400; public static uint MF_REMOVE = 0x1000; public static int GWL_STYLE = -16; public static int WS_CHILD = 0x40000000; //child window public static int WS_BORDER = 0x00800000; //window with border public static int WS_DLGFRAME = 0x00400000; //window with double border but no title public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar public static int WS_SYSMENU = 0x00080000; //window menu #endregion public static void WindowsReStyle() { Process[] Procs = Process.GetProcesses(); foreach (Process proc in Procs) { if (proc.ProcessName.StartsWith("notepad")) { IntPtr pFoundWindow = proc.MainWindowHandle; int style = GetWindowLong(pFoundWindow, GWL_STYLE); //get menu IntPtr HMENU = GetMenu(proc.MainWindowHandle); //get item count int count = GetMenuItemCount(HMENU); //loop & remove for (int i = 0; i < count; i++) RemoveMenu(HMENU, 0, (MF_BYPOSITION | MF_REMOVE)); //force a redraw DrawMenuBar(proc.MainWindowHandle); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_SYSMENU)); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION)); } } }

  • Problem with return 2 libc method

    - by jth
    Hi, I'am trying to understand the return2libc method. I'am using an ubuntu linux 9.10, 32 bit with ASLR disabled. In theory, it sounds quite easy, overwrite the saved eip with the address of system() (or whatever function you want), then put the address to which system() should return and after that, the parameter for system, the "/bin/bash"-string. But what happens is that my exploit keeps segfaulting the vulnerable program. I assume something with the system()-address went wrong. This is what I did so far: Determined the address of system(): (gdb) print system $1 = {<text variable, no debug info>} 0x167020 <system> (gdb) x/x system 0x167020 <system>: 0x890cec83 I used the subsequent x/x system because those 3 bytes returned by print system looks like an index in some sort of jumptable (PLT?), so I assume 0x890cec83 is the right address which is used to overwrite the saved eip. After that I determined the address of the /bin/bash string in memory, using a small C program which basically consists of this line: printf("Address of string /bin/bash: %p\n", getenv("SHELL")); Then I looked a little bit around in the memory and fount /bin/bash: (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" After I gathered this information, I filled the buffer: (gdb) b 9 Breakpoint 1 at 0x8048407: file victim.c, line 9. (gdb) r `perl -e 'print "A"x9 . "\x83\xec\x0c\x89FAKE\xca\f6\ff\bf";'` Breakpoint 1, main (argc=1111638594, argv=0xc360cca) at victim.c:10 10 return 0; (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" Stack frame looks like this: (gdb) i f Stack level 0, frame at 0xbffff440: eip = 0x8048407 in main (victim.c:10); saved eip 0x890cec83 source language c. Arglist at 0xbffff438, args: argc=1111638594, argv=0xc360cca Locals at 0xbffff438, Previous frame's sp is 0xbffff440 Saved registers: ebp at 0xbffff438, eip at 0xbffff43c This seems all right to me, saved eip was overwritten with the (hopefully) correct system()-address, return address for system was set to "FAKE" (shouldn't matter) and the address of /bin/bash also seems to be correct. When I'am continuing the execution, victim segfaults on some strange address and certainly not in 0x890cec83: (gdb) cont Continuing. Program received signal SIGSEGV, Segmentation fault. 0x0804840d in main (argc=Cannot access memory at address 0x41414149 ) at victim.c:11 11 } Has anyone an explanation or a hint what happens here and why the execution isn't redirected to 0x890cec83? Thanks in advance, any hint, and be it only vague, would be appreciated. I have no idea why this doesn't work.

  • Cure for puzzle piece programming habits?

    - by Recursion
    Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

  • How to validate Data Annotations with a MetaData class

    - by Micah
    I'm trying to validate a class using Data Annotations but with a metadata class. [MetadataType(typeof(TestMetaData))] public class Test { public string Prop { get; set; } internal class TestMetaData { [Required] public string Prop { get; set; } } } [Test] [ExpectedException(typeof(ValidationException))] public void TestIt() { var invalidObject = new Test(); var context = new ValidationContext(invalidObject, null, null); context.MemberName = "Prop"; Validator.ValidateProperty(invalidObject.Prop, context); } The test fails. If I ditch the metadata class and just decorated the property on the actual class it works fine. WTH am I doing wrong? This is putting me on the verge of insanity. Please help.

    Delphi 2010, dbExpress, and MS SQL Server 2005 DB Ok, I am trying to make a connection to a MS SQL 2005 DB using Delphi 2010 & DBExpress.

  • Is it worth caching a Dictionary for foreign key values in ASP.net?

    - by user169867
    I have a Dictionary<int, string> cached (for 20 minutes) that has ~120 ID/Name pairs for a reference table. I iterate over this collection when populating dropdown lists and I'm pretty sure this is faster than querying the DB for the full list each time. My question is more about if it makes sense to use this cached dictionary when displaying records that have a foreign key into this reference table. Say this cached reference table is a EmployeeType table. If I were to query and display a list of employee names and types should I query for EmployeeName and EmployeeTypeID and use my cached dictionary to grab the EmployeeTypeIDs name as each record is displayed or is it faster to just have the DB grab the EmployeeName and JOIN to get the EmployeeType string bypassing the cached Dictionary all together. I know both will work but I'm interested in what will perform the fastest. Thanks for any help.

  • basic boost date_time input format question

    - by Chris H
    I've got a pointer to a string, (char *) as input. The date/time looks like this: Sat, 10 Apr 2010 19:30:00 I'm only interested in the date, not the time. I created an "input_facet" with the format I want: boost::date_time::date_input_facet inFmt("%a %d %b %Y"); but I'm not sure what to do with it. Ultimately I'd like to create a date object from the string. I'm pretty sure I'm on the right track with that input facet and format, but I have no idea how to use it. Thanks.

  • Kind of stumped with some basic C# constructors.

    public class Parser { Downloader download = new Downloader(); HtmlDocument Page; public Parser(string MovieTitle) { Page = download.FindMovie(MovieTitle); } public Parser(string ActorName) { Page = download.FindActor(ActorName); } } I want to create a constructor that will allow other developers who use this library to easily create a Parser object with the relevant HtmlDocument already loaded as soon as it's done creating it. The problem lies in that a constructor cannot exist twice with the same type of parameters. Sure I can tell the logical difference between the two paramters, but the computer can't. Any suggestions on how to handle this? Thank you!

  • Website often sticks, but clicking the link again everything loads fine

    - by Dave
    Hi I have a website, which normally is very fast, however in the last week or two we're run into a problem whereby randomly if you click a link the browser will just sit there with the throbber spinning but the page doesn't appear to load If you click the link again it then responds straight away This doesn't seem to be limited to Chrome, Firefox or IE as we've tried all with all having same problems The site is build in ASP and connects to a MySQL database and runs on a dedicated windows 2003 server The firewalls were changed in the data centre recently to pixies but I've not been able to reproduce the problem outside of the office Within the office, we have 11 people (only 7 today and still experiencing problems) connected to a 7MB ADSL connection with Eclipse I have made some changes to the network in the office, namely wiring 4 desks back to the main 24 port switch rather than to small 5 port which then linked on to the 24 port switch... however we were having problems before this was done, and I did this to try and rule out an issue with the switch We have a backup ADSL connection, so I may try switching to that, or switching to a different router, but do you think this is a likely issue? Failing that, what else would you check? Thanks, sorry for length! Dave

  • Automated Oracle Schema Migration Tool

    - by Dave Jarvis
    What are some tools (commercial or OSS) that provide a GUI-based mechanism for creating schema upgrade scripts? To be clear, here are the tool responsibilities: Obtain connection to recent schema version (called "source"). Obtain connection to previous schema version (called "target"). Compare all schema objects between source and target. Create a script to make the target schema equivalent to the source schema ("upgrade script"). Create a rollback script to revert the source schema, used if the upgrade script fails (at any point). Create individual files for schema objects. The software must: Use ALTER TABLE instead of DROP and CREATE for renamed columns. Work with Oracle 10g or greater. Create scripts that can be batch executed (via command-line). Trivial installation process. (Bonus) Create scripts that can be executed with SQL*Plus. Here are some examples (from StackOverflow, ServerFault, and Google searches): Change Manager Oracle SQL Developer Software that does not meet the criteria, or cannot be evaluated, includes: TOAD PL/SQL Developer - Invalid SQL*Plus statements. Does not produce ALTER statements. SQL Fairy - No installer. Complex installation process. Poorly documented. DBDiff - Crippled data set evaluation, poor customer support. OrbitDB - Crippled data set evaluation. SchemaCrawler - No easily identifiable download version for Oracle databases. SQL Compare - SQL Server, not Oracle. LiquiBase - Requires changing the development process. No installer. Manually edit config files. Does not recognize its own baseUrl parameter. The only acceptable crippling of the evaluation version is by time. Crippling by restricting the number of tables and views hides possible bugs that are only visible in the software during the attempt to migrate hundreds of tables and views.

  • Using a boost::fusion::map in boost::spirit::karma

    - by user1097105
    I am using boost spirit to parse some text files into a data structure and now I am beginning to generate text from this data structure (using spirit karma). One attempt at a data structure is a boost::fusion::map (as suggested in an answer to this question). But although I can use boost::spirit::qi::parse() and get data in it easily, when I tried to generate text from it using karma, I failed. Below is my attempt (look especially at the "map_data" type). After some reading and playing around with other fusion types, I found boost::fusion::vector and BOOST_FUSION_DEFINE_ASSOC_STRUCT. I succeeded to generate output with both of them, but they don't seem ideal: in vector you cannot access a member using a name (it is like a tuple) -- and in the other solution, I don't think I need both ways (member name and key type) to access the members. #include <iostream> #include <string> #include <boost/spirit/include/karma.hpp> #include <boost/fusion/include/map.hpp> #include <boost/fusion/include/make_map.hpp> #include <boost/fusion/include/vector.hpp> #include <boost/fusion/include/as_vector.hpp> #include <boost/fusion/include/transform.hpp> struct sb_key; struct id_key; using boost::fusion::pair; typedef boost::fusion::map < pair<sb_key, int> , pair<id_key, unsigned long> > map_data; typedef boost::fusion::vector < int, unsigned long > vector_data; #include <boost/fusion/include/define_assoc_struct.hpp> BOOST_FUSION_DEFINE_ASSOC_STRUCT( (), assocstruct_data, (int, a, sb_key) (unsigned long, b, id_key)) namespace karma = boost::spirit::karma; template <typename X> std::string to_string ( const X& data ) { std::string generated; std::back_insert_iterator<std::string> sink(generated); karma::generate_delimited ( sink, karma::int_ << karma::ulong_, karma::space, data ); return generated; } int main() { map_data d1(boost::fusion::make_map<sb_key, id_key>(234, 35314988526ul)); vector_data d2(boost::fusion::make_vector(234, 35314988526ul)); assocstruct_data d3(234,35314988526ul); std::cout << "map_data as_vector: " << boost::fusion::as_vector(d1) << std::endl; //std::cout << "map_data to_string: " << to_string(d1) << std::endl; //*FAIL No 1* std::cout << "at_key (sb_key): " << boost::fusion::at_key<sb_key>(d1) << boost::fusion::at_c<0>(d1) << std::endl << std::endl; std::cout << "vector_data: " << d2 << std::endl; std::cout << "vector_data to_string: " << to_string(d2) << std::endl << std::endl; std::cout << "assoc_struct as_vector: " << boost::fusion::as_vector(d3) << std::endl; std::cout << "assoc_struct to_string: " << to_string(d3) << std::endl; std::cout << "at_key (sb_key): " << boost::fusion::at_key<sb_key>(d3) << d3.a << boost::fusion::at_c<0>(d3) << std::endl; return 0; } Including the commented line gives lots of pages of compilation errors, among which notably something like: no known conversion for argument 1 from ‘boost::fusion::pair’ to ‘double’ no known conversion for argument 1 from ‘boost::fusion::pair’ to ‘float’ Might it be that to_string needs the values of the map_data, and not the pairs? Though I am not good with templates, I tried to get a vector from a map using transform in the following way template <typename P> struct take_second { typename P::second_type operator() (P p) { return p.second; } }; // ... inside main() pair <char, int> ff(32); std::cout << "take_second (expect 32): " << take_second<pair<char,int>>()(ff) << std::endl; std::cout << "transform map_data and to_string: " << to_string(boost::fusion::transform(d1, take_second<>())); //*FAIL No 2* But I don't know what types am I supposed to give when instantiating take_second and anyway I think there must be an easier way to get (iterate over) the values of a map (is there?) If you answer this question, please also give your opinion on whether using an ASSOC_STRUCT or a map is better.

  • Why did this work? ( php dot notation )

    - by Daniel
    Hi, I was writing some php code after a long sint doing ruby and I accidently wrote this: [root@ip-10-160-47-98 test]# cat run.php <?php class MyTest { public function run() { var_dump(this.test); } } $object = new MyTest(); $object->run(); [root@ip-10-160-47-98 test]# php run.php string(8) "thistest" [root@ip-10-160-47-98 test]# Now, this.test should have been $this-test, but the compiler was actually happy to let this run. Does anyone know how (this.test) got converted into a string "thistest"? Compiled and run on php 5.3.2 amazon instance ami-e32273a6 (CentOS 5.4) -daniel

  • How to display unique success messages on jquery form validation

    - by mastah
    Hi guys, hope you can help me on this one, I'm currently using this: jQuery plugin:validation (Homepage) I've been reading related questions here, but this one is the closest get. http://stackoverflow.com/questions/1863448/jquery-validation-on-success from the plugin's documentation http://docs.jquery.com/Plugins/Validation/validate#toption success String, Callback If specified, the error label is displayed to show a valid element. If a String is given, its added as a class to the label. If a Function is given, its called with the label (as a jQuery object) as its only argument. That can be used to add a text like "ok!". Currently I'm only object given to me is the label, and I can only add text to it. Now what I want is to have unique success message. For example: username field will have a success message: 'username okay!' email = 'email seems right' something along those lines, instead of displaying just one generic success message on all the fields. Thanks in advanced :)

  • I need a groovy criteria to get all the elements after i make sort on nullable inner object

    - by user1773876
    I have two domain classes named IpPatient,Ward as shown below. class IpPatient { String ipRegNo Ward ward static constraints = { ward nullable:true ipRegNo nullable:false } } class Ward { String name; static constraints = { name nullable:true } } now i would like to create criteria like def criteria=IpPatient.createCriteria() return criteria.list(max:max , offset:offset) { order("ward.name","asc") createAlias('ward', 'ward', CriteriaSpecification.LEFT_JOIN) } At present IpPatient table has 13 records, where 8 records of IpPatient doesn't have ward because ward can be null. when i sort with wardName i am getting 5 records those contain ward. I need a criteria to get all the elements after i make sort on nullable inner object.

  • Finite State Machine Spellchecker

    - by Durell
    I would love to have a debugged copy of the finite state machine code below. I tried debugging but could not, all the machine has to do is to spell check the word "and",an equivalent program using case is welcomed. #include<cstdlib> #include<stdio.h> #include<string.h> #include<iostream> #include<string> using namespace std; char in_str; int n; void spell_check() { char data[256]; int i; FILE *in_file; in_file=fopen("C:\\Users\\mytorinna\\Desktop\\a.txt","r+"); while (!feof(in_file)) { for(i=0;i<256;i++) { fscanf(in_file,"%c",in_str); data[i]=in_str; } //n = strlen(in_str); //start(data); cout<<data; } } void start(char data) { // char next_char; //int i = 0; // for(i=0;i<256;i++) // if (n == 0) { if(data[i]="a") { state_A(); exit; } else { cout<<"I am comming"; } // cout<<"This is an empty string"; // exit();//do something here to terminate the program } } void state_A(int i) { if(in_str[i] == 'n') { i++; if(i<n) state_AN(i); else error(); } else error(); } void state_AN(int i) { if(in_str[i] == 'd') { if(i == n-1) cout<<" Your keyword spelling is correct"; else cout<<"Wrong keyword spelling"; } } int main() { spell_check(); system("pause"); return 0; }
