Hey, I am currently following a code skeleton to implement the missing code for some function. Below is only some part of the implementation I've done so far. Yes it is not much yet... I got stuck for the implementation of the [B]list_add()[/B] function. What I want to do there …

Hi I've been struggling with this for a very long time now. And I can't seem to get it done. I want to make an array, dynamic allocted array. Which act something like an vector (I know c++ has vector). So my approach was to create a [B]list_add() [/B]function. Its …

Hello I've a question when creating a class with functions. e.g. [CODE=javascript] function constructor() { this.myFunc = function() { return "Hello World"; } } [/CODE] do I have to write the function in that way? this.funcName = function() for every function in that class? Because when I tried to write …

Hello, I'm reading a chapter about virtual function. So what I know is that virtual function is equal to abstract functions. It is enough to declare one function virtual to make the class into an abstract class. E.g. [CODE=cpp] class Base { public: Base(); virtual set(); } [/CODE] Now I'm …

Hello, I am having problem to define a constuctor of a class with private member which is also of a const type. When I try to compile it complains that the const members do not have initalized data. Hmm, anyway it works fine if I remove const. However is it …

Hello, I've written couple of overloaded operators in my file containing Set declarations. I want to use these operators within the declaration file. However it seems it isn't used.
