There many ways to find memory leaks, One of the ways is by
using MFC class. And another way is using Purify tools...

CMemorState is a MFC class by which we can find the memory
leaks. Below is a sample code to find the same.

#ifdef _DEBUG
CMemoryState oldState, newState, diffState;
oldState.Checkpoint();
#endif
int* a = new int[10];
#ifdef _DEBUG
newState.Checkpoint();
if(diffState.Difference(oldState, newState))
{
TRACE0("Memory Leaked");
}
#endif

There is a pretty easiest way to identify whether ur application is having any memory leak. By using the macro called DEBUG_NEW

define this macro on each of urs cpp file.
like #define DEBUG_NEW

then if u run once ur application in debug mode, it will show each variable which has not been released the memory properly.

Answer / gopal sodhani

macro should be
#define new DEBUG_NEW, in such case once you insert this
directive, the preprocessor will insert DEBUG_NEW wherever
you use new, and MFC does the rest.
