  • Type Declaration - Pointer Asterisk Position

    - by sahs
    Hello, in C++, the following means "allocate memory for an int pointer": int* number; So, the asterisk is part of the variable type; without it, that would mean something else (that's why I usually don't separate the asterisk from the variable type). Then what is the reason the asterisk is considered something else, instead of being part of the type? For example, it seems better, if the following meant "allocate memory for two int pointers": int* number1, number2; Am I wrong?

  • Calling a jQuery method at declaration time, and then onEvent

    - by cesarsalazar
    I've been writing JS (mainly jQuery) for quite a few months now, but today I decided to make my first abstraction as a jQuery method. I already have working code but I feel/know that I'm not doing it the right way, so I come here for some enlightenment. Note: Please do not reply that there's already something out there that does the trick as I already know that. My interest in this matter is rather educational. What my code is intended to do (and does): Limit the characters of a textfield and change the color of the counter when the user is approaching the end. And here's what I have: $(function(){ $('#bio textarea').keyup(function(){ $(this).char_length_validation({ maxlength: 500, warning: 50, validationSelector: '#bio .note' }) }) $('#bio textarea').trigger('keyup'); }) jQuery.fn.char_length_validation = function(opts){ chars_left = opts.maxlength - this.val().length; if(chars_left >= 0){ $(opts.validationSelector + ' .value').text(chars_left); if(chars_left < opts.warning){ $(opts.validationSelector).addClass('invalid'); } else{ $(opts.validationSelector).removeClass('invalid'); } } else{ this.value = this.value.substring(0, opts.maxlength); } } In the HTML: <div id="bio"> <textarea>Some text</textarea> <p class="note> <span class="value">XX</span> <span> characters left</span> </p> </div> Particularly I feel really uncomfortable binding the event each on each keyup instead of binding once and calling a method later. Also, (and hence the title) I need to call the method initially (when the page renders) and then every time the user inputs a character. Thanks in advance for your time :)

  • Confusing Javascript class declaration

    - by clutch
    I have some third-party Javascript that has statements like this: FOO = function() { ...functions() ... return { hash } }(); It is working as designed but I'm confused by it. Can anybody define what this structure is doing? Is it just a weird way to create a class?

  • friend declaration block an external function access to the private section of a class

    - by MiP
    I'm trying to force function caller from a specific class. For example this code bellow demonstrate my problem. I want to make 'use' function would be called only from class A. I'm using a global namespace all over the project. a.h #include "b.h" namespace GLOBAL{ class A{ public: void doSomething(B); } } a.cpp #include "a.h" using namespace GLOBAL; void A::doSomething(B b){ b.use(); } b.h namespace GLOBAL{ class B{ public: friend void GLOBAL::A::doSomething(B); private: void use(); } Compiler says: ‘GLOBAL::A’ has not been declared ‘void GLOBAL::B::use()’ is private Can anyone help here ? Thanks a lot, Mike.

  • Java Method declaration

    - by user1701604
    I'm trying to declare a method for my program that takes only a 5 digit integer and for each digit of the integer, reads a value from the program and prints it out. I understand this isn't very clear but im having trouble relaying what I mean. I understand it will be some sort of for loop to read each digit of the integer individually until something reaches 5. Something like the charAt() string method but works for digits.

  • C# Implicit array declaration

    - by The.Anti.9
    Basically, I want to be able to use string.Split(char[]) without actually defining a char array as a separate variable. I know in other languages you could do like string.split([' ', '\n']); or something like that. How would I do this in C#?

  • A general declaration for all inherited classes

    - by Soham
    Consider, there is a class called SuperClass from which, ClassA, ClassB, ClassC is derived. From each one of those derived Classes, there are further more two classes are derived each called ChildClassAA and ChildClassAB[AB stands for Bth Child class from the Ath Class.Lets not really pull our hair on this nomenclature]. Now, ideally, I want to declare a general type as a private member of another Class say IndependentClass which can be initialized during run time as either of the objects of type ClassAor ClassB or ClassC and even the derived classes like ClassAA or ClassAB. Is there a possible way to do it?

  • c++ variable declaration

    - by swan
    Hello, Im wondering if this code: int main(){ int p; for(int i = 0; i < 10; i++){ p = ...; } return 0 } is exactly the same as that one int main(){ for(int i = 0; i < 10; i++){ int p = ...; } return 0 } in term of efficiency ? I mean, the p variable will be recreated 10 times in the second example ?

  • I changed the web service declaration and then wsimport says that I have a repeated message

    - by Oso
    I had a Web service method working fine on Tomcat as deployed by Netbeans 6.8. Then I had to add a new parameter for the same method so I erased the method and then added a new one with the same name but different parameters. After that, ws-import keeps on telling me that I have duplicated messages for such method, and if I remove the new one, the WSDL will still show me the old one with the old parameter list. How do I get rid of the old one? thanks in advance.

  • Java compiler rejects variable declaration with parameterized inner class

    - by Johansensen
    I have some Groovy code which works fine in the Groovy bytecode compiler, but the Java stub generated by it causes an error in the Java compiler. I think this is probably yet another bug in the Groovy stub generator, but I really can't figure out why the Java compiler doesn't like the generated code. Here's a truncated version of the generated Java class (please excuse the ugly formatting): @groovy.util.logging.Log4j() public abstract class AbstractProcessingQueue <T> extends nz.ac.auckland.digitizer.AbstractAgent implements groovy.lang.GroovyObject { protected int retryFrequency; protected java.util.Queue<nz.ac.auckland.digitizer.AbstractProcessingQueue.ProcessingQueueMember<T>> items; public AbstractProcessingQueue (int processFrequency, int timeout, int retryFrequency) { super ((int)0, (int)0); } private enum ProcessState implements groovy.lang.GroovyObject { NEW, FAILED, FINISHED; } private class ProcessingQueueMember<E> extends java.lang.Object implements groovy.lang.GroovyObject { public ProcessingQueueMember (E object) {} } } The offending line in the generated code is this: protected java.util.Queue<nz.ac.auckland.digitizer.AbstractProcessingQueue.ProcessingQueueMember<T>> items; which produces the following compile error: [ERROR] C:\Documents and Settings\Administrator\digitizer\target\generated-sources\groovy-stubs\main\nz\ac\auckland\digitizer\AbstractProcessingQueue.java:[14,96] error: improperly formed type, type arguments given on a raw type The column index of 96 in the compile error points to the <T> parameterization of the ProcessingQueueMember type. But ProcessingQueueMember is not a raw type as the compiler claims, it is a generic type: private class ProcessingQueueMember <E> extends java.lang.Object implements groovy.lang.GroovyObject { ... I am very confused as to why the compiler thinks that the type Queue<ProcessingQueueMember<T>> is invalid. The Groovy source compiles fine, and the generated Java code looks perfectly correct to me too. What am I missing here? Is it something to do with the fact that the type in question is a nested class? (in case anyone is interested, I have filed this bug report relating to the issue in this question) Edit: Turns out this was indeed a stub compiler bug- this issue is now fixed in 1.8.9, 2.0.4 and 2.1, so if you're still having this issue just upgrade to one of those versions. :)

  • ANTLR C grammar, optional init_declarator_list?

    - by eisbaw
    Hello, In the ANSI C grammar for ANTLR v3 ( http://antlr.org/grammar/1153358328744/C.g ), how can init_declarator_list be optional in rule declaration ? Instead of: | declaration_specifiers init_declarator_list? ';' -I would say: | declaration_specifiers init_declarator_list ';' What part of the C standard allows statements like: int; EDIT: I just tried, it is allowed! Okay then, why is it allowed?

  • arrays declaration and addressing

    - by avinash
    I have a few straightforward questions:- Is the following correct according to a normal c++ compiler? int arr[3][4]; void func(int *a, int m, int n) { int i,j; cin>>i>>j; cout<< a[i*n + j]; //is this way of addressing correct provided 0<=i<m and 0<=j<n } int main() { func((int*)arr, 3,4); } If the bounds of an array strictly has to be a constant expression, why doesn't the following generate compiler errors? int func(int m, int n) { int arr[m][n]; //m and n are not known until run time }

  • Declaration of struct variables in other class when obtained by getters

    - by liaK
    Hi, I am using Qt 4.5 so do C++. I have a class like this class CClass1 { private: struct stModelDetails { QString name; QString code; ..... // only variables and no functions over here }; QList<stModelDetails> m_ModelDetailsList; public: QList<stModelDetails> getModelDetailsList(); ... }; In this I have functions that will populate the m_ModelDetailsList; I have another class say CClassStructureUsage, where I will call the getModelDetailsList() function. Now my need is that I have to traverse the QList and obtain the name, code from each of the stModelDetails. Now the problem is even the CClass1's header file is included it is not able to identify the type of stModelDetails in CClassStructureUsage. When I get the structure list by QList<stModelDetails> ModelList = obj->getModelInformationList(); it says stModelDetails : undeclared identifier. How I can able to fetch the values from the structure? Am I doing anything wrong over here?

  • List.AddRange inline declaration

    - by AJ
    Hello, This may seem an easy question, but not to me, also a search has led to nothing. Up until now the only .net programming I have done is with Delphi Prism. With Prism I can do things like: var l := new List<String>(['A','B','C']); or var l := new List<String>; l.AddRange(['A','B','C']; but can I do a similar thing in C#, or do I have to do it like: var a = new String[] {"A","B","C"}; var l = new List<String>(a); Thanks, AJ

  • C++ header file and function declaration ending in "= 0"

    - by Adam
    hi, I have the following code inside the .h file and I'm not sure what does the assignment statement do and how is it called properly? virtual void yield() = 0; I thought that the function returns a value of 0 by default but since this function returns void I am a little bit confused. Can anyone comment on this and maybe say how can I refer to this assignment, I mean how is it called in C++ jargon? Thanks.

  • jquery document.ready multiple declaration

    - by Hendry H.
    I realized that I can specify $(document).ready(function(){}); more than once. Suppose like this $(document).ready(function(){ var abc = "1122"; //do something.. }); $(document).ready(function(){ var abc = "def"; //do something.. }); Is this standard ? Those codes work on my FF (16.0.2). I just a little afraid that other browser may not. What actually happen ? How jQuery handle those code ? Thanks.

  • C/C++ definitions of functions

    - by Vit
    Yesterday, I have been watching discussion here, about compilers and linkers. It was about C library function definitions. I have never thought of that, so it inspired me to do some searching, but I cannot find exactly what I want. I wonder, what is the smallest syntax you need to add into your source code to enable just printf() function. I mean the function declaration from stdio.h you need.

  • javascript var declaration within loop

    - by Trouts
    hello, /*Test scope problem*/ for(var i=1; i<3; i++){ //declare variables var no = i; //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } it alerts "setting 1" and "setting 2" as expected, but after the timeout it outputs "test 2" twice - for some reason the variable "no" is not reset after the first loop... i've found only an "ugly" workaround... /*Test scope problem*/ var func=function(no){ //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } for(var i=1; i<3; i++){ func(i); } Any ideas on how to workaround this problem in a more direct way? or is this the only way?
