    Memory DeAllocation

    hi
    i declared a structure as shown below
    Struct Name
    {
    int *nPtr;
    float *fPtr;
    }

    In MFC, one command button click event, i added the following code and CDocClass has the structure as a member variable
    Name *str;

    In constructor it is initialized to NULL
    str = NULL
    CDocClass::OnBu ttonClicked()
    {
    if(str)
    {
    ...

      hi
      This is the source code that i used for several times,
      for(i = 0; i < 1000; i++)
      {
      int *ptr = new int[20000];
      for(int i = 0; i < 20000; i++)ptr[i] = 0;
      delete [] ptr;
      }

      In the task manager, look at the virtual memory size,
      when i allocate memroy the virtual memroy size increases..
      and when i deallocate the virtual memory size decreases in release mode but not in...

        Deallocating memory in C++

        hi
        i am working in VC++.
        In the foolowing code

        {
        int *p = NULL
        p = new int[2000];
        delete [] p;
        }

        i have allocated memeory using new and
        deallocated the meomory using delete.
        This releases the memory in release build.
        but didn't release the memory in debug mode.
        OS:Windows 2000
        Can anybody help me to find the reason?
