I''m sure there are plenty of free (or shareware) leak detectors (hint: search google). One option is using the Boehm-Demers-Weiser garbage collector in leak detection mode.

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