    • Hi Raju, Thanks for your feedback. Design patterns are in process. Regarding OOPs concept, i am continuously pushing. Can you be specific what you are looking for in oops concept and or if you want in any specific language?
      Thanks

  1. C# – Nice Explanation with simple examples to better understand concepts.
    Please add Design patterns .It would be of great help.

  2. Hi Rakesh. Thank you so much for doing this, I really enjoy going through the problems on this website. However, I’d like to point at a solution which might require some correction:

    in the section C++ programming -> pointer and references – >page 7:

    program:

    class X{

    public:
    X(){}
    ~X(){}
    };

    int main()
    {
    X *xPtr[5];
    xPtr[0] = new X();
    xPtr[1] = new X();
    xPtr[2] = new X();
    xPtr[3] = new X();
    xPtr[4] = new X();

    return 0;
    }

    Then what is difference between delete xPtr and delete [] xPtr ?

    Answer: Both will de-allocate memory, delete xPtr will call destructor only once but delete [] xPtr will call destructor 5 times that is for every object of the class.

    Correction: the program will crash at run time when it executes “delete xPtr” since xPtr is a pointer to the first element () of the array, and the array is created on the stack. I’ve tested it. Please verify once.
