In few words: you can't.

Check out tools like Valgrind to help you debugging memory leaks issues.

Some other things you should consider:

  • Use smart pointers so that you don't have do think about memory management,
  • Set your pointers to 0 after you free them, so that a further delete has no effect,
  • Use standard classes (vector, ...) instead of rolling your own,
  • Finally, don't use pointers (actually you almost can)
