Memory leak detection and analysis tool

Actually, I know it's necessary to free the memory allocated with malloc(), but I wonder if I can know there is some memory left being not collected if I forget to collect it with free().

You can use a tool like valgrind. Check out this video on how to use it, courtesy of Harvard's CS50 available on edx. It gives a very good explanation on how to use it, as well as some examples on both correct and incorrect code.

In addition to valgrind answers, you may link your executables against Boehm GC – C garbage collector that may run in leak detection mode.

What you are trying to do is impossible. Just keep track of all the memory you allocated and erase it when needed
