  • C++ Operator overloading - 'recreating the Vector'

    - by Wallter
    I am currently in a collage second level programing course... We are working on operator overloading... to do this we are to rebuild the vector class... I was building the class and found that most of it is based on the [] operator. When I was trying to implement the + operator I run into a weird error that my professor has not seen before (apparently since the class switched IDE's from MinGW to VS express...) (I am using Visual Studio Express 2008 C++ edition...) Vector.h #include <string> #include <iostream> using namespace std; #ifndef _VECTOR_H #define _VECTOR_H const int DEFAULT_VECTOR_SIZE = 5; class Vector { private: int * data; int size; int comp; public: inline Vector (int Comp = 5,int Size = 0) : comp(Comp), size(Size) { if (comp > 0) { data = new int [comp]; } else { data = new int [DEFAULT_VECTOR_SIZE]; comp = DEFAULT_VECTOR_SIZE; } } int size_ () const { return size; } int comp_ () const { return comp; } bool push_back (int); bool push_front (int); void expand (); void expand (int); void clear (); const string at (int); int operator[ ](int); Vector& operator+ (Vector&); Vector& operator- (const Vector&); bool operator== (const Vector&); bool operator!= (const Vector&); ~Vector() { delete [] data; } }; ostream& operator<< (ostream&, const Vector&); #endif Vector.cpp #include <iostream> #include <string> #include "Vector.h" using namespace std; const string Vector::at(int i) { this[i]; } void Vector::expand() { expand(size); } void Vector::expand(int n ) { int * newdata = new int [comp * 2]; if (*data != NULL) { for (int i = 0; i <= (comp); i++) { newdata[i] = data[i]; } newdata -= comp; comp += n; delete [] data; *data = *newdata; } else if ( *data == NULL || comp == 0) { data = new int [DEFAULT_VECTOR_SIZE]; comp = DEFAULT_VECTOR_SIZE; size = 0; } } bool Vector::push_back(int n) { if (comp = 0) { expand(); } for (int k = 0; k != 2; k++) { if ( size != comp ){ data[size] = n; size++; return true; } else { expand(); } } return false; } void Vector::clear() { delete [] data; comp = 0; size = 0; } int Vector::operator[] (int place) { return (data[place]); } Vector& Vector::operator+ (Vector& n) { int temp_int = 0; if (size > n.size_() || size == n.size_()) { temp_int = size; } else if (size < n.size_()) { temp_int = n.size_(); } Vector newone(temp_int); int temp_2_int = 0; for ( int j = 0; j <= temp_int && j <= n.size_() && j <= size; j++) { temp_2_int = n[j] + data[j]; newone[j] = temp_2_int; } //////////////////////////////////////////////////////////// return newone; //////////////////////////////////////////////////////////// } ostream& operator<< (ostream& out, const Vector& n) { for (int i = 0; i <= n.size_(); i++) { //////////////////////////////////////////////////////////// out << n[i] << " "; //////////////////////////////////////////////////////////// } return out; } Errors: out << n[i] << " "; error C2678: binary '[' : no operator found which takes a left-hand operand of type 'const Vector' (or there is no acceptable conversion) return newone; error C2106: '=' : left operand must be l-value As stated above, I am a student going into Computer Science as my selected major I would appreciate tips, pointers, and better ways to do stuff :D

  • Parsing content-disposion header's filename in multipart/from-data

    - by Artyom
    Hello According to RFC, in multipart/form-data content-disposition header filename field receives as parameter HTTP quoted string - string between quites where character '\' can escape any other ascii character. Problem web browsers don't do it. IE6 sends: Content-Disposition: form-data; name="file"; filename="z:\tmp\test.txt" Instead of expected Content-Disposition: form-data; name="file"; filename="z:\\tmp\\test.txt" Which should be parsed as z:tmptest.txt according to rules instead of z:\tmp\test.txt. Firefox, Konqueror and Chrome don't escape " characters for example: Content-Disposition: form-data; name="file"; filename=""test".txt" Instead of expected Content-Disposition: form-data; name="file"; filename="\"test\".txt" So... how would you suggest to deal with this issue?

  • How to feed data over STDIN to multiple external commands in ruby.

    This question is a bit like my previous (answered) question: How to run multiple external commands in the background in ruby. But, in this case I am looking for a way to feed ruby strings over STDIN to external processes, something like this (the code below is not valid but illustrates my goal): #!/usr/bin/ruby str1 = 'In reality a relatively large string.....' str2 = 'Another large string' str3 = 'etc..' spawn 'some_command.sh', :stdin => str1 spawn 'some_command.sh', :stdin => str2 spawn 'some_command.sh', :stdin => str3 Process.waitall

  • CSS line wrapping

    - by Mic
    Given a block container <div> this is a very long string which contains a bunch of characters that I want to break at container edges. </div> are there any css properties I can set to force it to break when it reaches the container width, regardless of the contents of the string, for example a break like: this is a ve ry long stri ng which ... is pretty much what I want. Right now, it seems to always prefer to break at whitespace characters or other special characters (such as /).

  • Fill object data from several tables using hibernate mapping

    - by Udo Fholl
    Hi all, I'd like to know if it is possible to fill up a class data from database using the hibernate hbm (mapping). For instance: public class someClass { List<OtherClass> otherClasses; List<YetAnotherClass> yetAnotherClasses; //Constructors ? class OtherClass { String name; //setters, getters } class YetAnotherClass { String name; //setters, getters } //setters, getters } Using an hbm can I fill in the data from tables OTHER_CLASS_TABLE and YET_ANOTHER_CLASS_TABLE? I have no such SOME_CLASS_TABLE since this info is for viewing only. I've been playing with the <join table=""><subselect> and different constructors... But it is not working Thanks! Sorry for my english!

  • Where can I find a list of reserved words for Oracle fulltext search?

    - by Tyronomo
    I've a client testing the full text (example below) search on a new Oracle UCM site. The random text string they chose to test was 'test only'. Which failed; from my testing it seems 'only' is a reserved word, as it is never returned from a full text search (it is returned from metadata searches). I've spent the morning searching oracle.com and found this which seems pretty comprehensive, yet does not have 'only'. So my question is thus, is 'only' a reserved word. Where can I find a complete list of reserved words for Oracle full text search (10g)? Full text search string example; (<ftx>test only</ftx>)

  • PHP - HTML Purifier - hello w<o>rld/world tutorial striptags

    - by JW
    I am just looking into using HTML Purifier to ensure that a user-inputed string (that represents the name of a person) is sanitized. I do not want to allow any html tags, script, markup etc - I just want the alpha, numeric and normal punctuation characters. The sheer number of options available for HTML Purifier is daunting and, as far as i can see, the docs do not seem to have a beggining/middle or end see: http://htmlpurifier.org/docs Is there a simple hello world tutorial online that shows how to sanitize a string removing all the bad stuff out of it. I am also considering just using strip tags: http://php.net/manual/en/function.strip-tags.php or PHP's in built data sanitizing http://us.php.net/manual/en/book.filter.php

  • Searching a table MySQL & PHP.

    - by S1syphus
    I want to be able to search through a MySQL table using values from a search string, from the url and display the results as an XML output. I think I have got the formatting and declaring the variables from the search string down. The issue I have is searching the entire table, I've looked over SO for previous answers, and they all seem to have to declare each column in the table to search through. So for example my database layout is as follows: **filesindex** -filename -creation -length -wall -playlocation First of all would the following be appropriate: $query = "SELECT * FROM filesindex WHERE filename LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE creation LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE length LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE wall LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE location LIKE '".$searchterm."%'"; Or ideally, is there an easier way that involves less hardcoding to search a table. Any ideas? Thanks

  • HelloWebView Sample: now using SDK 3 and getting killed

    - by Tim
    Hey Folks, Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder. Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed. Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator? The main.xml, manifest, and console output are below. Let me know if you need more information.

  • java - POST vs JDBC

    OK so here's the code: import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.URL; public class Main { public static void main(String[] args) { try { URL my_url = new URL("http://www.viralpatel.net/blogs/"); BufferedReader br = new BufferedReader(new InputStreamReader(my_url.openStream())); String strTemp = ""; while(null != (strTemp = br.readLine())){ System.out.println(strTemp); } } catch (Exception ex) { ex.printStackTrace(); } } } Using this method I can use POST and GET methods using PHP scripts. I can then use the PHP scripts to the MySQL database which in turn outputs back to the java applet. Is this possible? (and safer?) Thanks.

  • SQLAlchemy - how to map against a read-only (or calculated) property

    - by Jeff Peck
    I'm trying to figure out how to map against a simple read-only property and have that property fire when I save to the database. A contrived example should make this more clear. First, a simple table: meta = MetaData() foo_table = Table('foo', meta, Column('id', String(3), primary_key=True), Column('description', String(64), nullable=False), Column('calculated_value', Integer, nullable=False), ) What I want to do is set up a class with a read-only property that will insert into the calculated_value column for me when I call session.commit()... import datetime def Foo(object): def __init__(self, id, description): self.id = id self.description = description @property def calculated_value(self): self._calculated_value = datetime.datetime.now().second + 10 return self._calculated_value According to the sqlalchemy docs, I think I am supposed to map this like so: mapper(Foo, foo_table, properties = { 'calculated_value' : synonym('_calculated_value', map_column=True) }) The problem with this is that _calculated_value is None until you access the calculated_value property. It appears that SQLAlchemy is not calling the property on insertion into the database, so I'm getting a None value instead. What is the correct way to map this so that the result of the "calculated_value" property is inserted into the foo table's "calculated_value" column?

  • java timer on current instance

Essentially I need the loop in newGame() to run for a minute or so before endGame() is invoked on the current instance. However, using the Timer class I'm not sure how I would invoke the method I need on the current instance since I can't pass any parameters to the timertasks run method? Is there an easy way to do this or am I going about this the wrong way? (note: this is a console project only, no GUI) ========== code edited I've changed the code to the above following the recommendations, and it works almost as I expect however the thread still doesnt seem to end properly. I was the while loop would die and control would eventually come back to the main method. Any ideas?

    Hi Friends, I want to write a code to search for method defination and methods called in a c# file. So obviously my pattern should search for text like 1.public void xyz(blahtype blahvalue); 2.string construct = SearchData(blahvalue); Has anyone done similar to this, is Regex helpful in this case. if yes provide me the pattern. Any other workarounds. I dont know reflection(will it help in my case) Thanks, you guys gave it a try, i did not know this wud be so complex. All i wanted to do was suppose i have method like this public method1(int val) { method2(); method3(); } void method2(int val2) { method4() } i wanted to construct a string as Method1:Method2:method4 and Method1:Method3....

  • Checking if an int is prime more efficiently

    - by SipSop
    I recently was part of a small java programming competition at my school. My partner and I have just finished our first pure oop class and most of the questions were out of our league so we settled on this one (and I am paraphrasing somewhat): "given an input integer n return the next int that is prime and its reverse is also prime for example if n = 18 your program should print 31" because 31 and 13 are both prime. Your .class file would then have a test case of all the possible numbers from 1-2,000,000,000 passed to it and it had to return the correct answer within 10 seconds to be considered valid. We found a solution but with larger test cases it would take longer than 10 seconds. I am fairly certain there is a way to move the range of looping from n,..2,000,000,000 down as the likely hood of needing to loop that far when n is a low number is small, but either way we broke the loop when a number is prime under both conditions is found. At first we were looping from 2,..n no matter how large it was then i remembered the rule about only looping to the square root of n. Any suggestions on how to make my program more efficient? I have had no classes dealing with complexity analysis of algorithms. Here is our attempt. public class P3 { public static void main(String[] args){ long loop = 2000000000; long n = Integer.parseInt(args[0]); for(long i = n; i<loop; i++) { String s = i +""; String r = ""; for(int j = s.length()-1; j>=0; j--) r = r + s.charAt(j); if(prime(i) && prime(Long.parseLong(r))) { System.out.println(i); break; } } System.out.println("#"); } public static boolean prime(long p){ for(int i = 2; i<(int)Math.sqrt(p); i++) { if(p%i==0) return false; } return true; } } ps sorry if i did the formatting for code wrong this is my first time posting here. Also the output had to have a '#' after each line thats what the line after the loop is about Thanks for any help you guys offer!!!

  • Sending BCC emails using a SMTP server?

    - by Alix Axel
    I've had this noted down on some of my code for a while: /** * Add a BCC. * * Note that according to the conventions of the SMTP protocol all * addresses, including BCC addresses, are included in every email as it * is sent over the Internet. The BCC addresses are stripped off blind * copy email only at the destination email server. * * @param string $email * @param string $name * @return object Email */ I don't remember where I got it from but that shouldn't be relevant to this question. Basically, whenever I try to send an email with BCCs via SMTP the BCC addresses are not hidden - I've read the whole RFC for the SMTP protocol (a couple years ago) and I don't think I'm missing anything. The strange thing is, if I send an email with BCCs using the built-in mail() function everything works just right and I've no idea why - I would like to roll my own email sender but I fail to understand this. Can someone please shed some light into this dark subject?
