To enable memory-checking in VC++ add the following at the start of your main-function:

        
#ifndef NDEBUG
int flag = _CrtSetDbgFlag (_CRTDBG_REPORT_FLAG);
flag |= _CRTDBG_LEAK_CHECK_DF;
_CrtSetDbgFlag (flag);
#endif


The #ifndef NDEBUG ensures that memory-checking is only enabled when you do debug-runs.
You also need to include the crtdbg.h file.

Unfortunately, with this setup you will only be told the size of the leak and a rather inscrutable hex-code.
You can, however, add the following code to your program (before your functions):


  
#ifndef NDEBUG
#define new new (_NORMAL_BLOCK, __FILE__, __LINE__)

#define malloc(size) _malloc_dbg(size, _NORMAL_BLOCK, __FILE__, __LINE__)

#endif
