Question

4. Write a simple program that allocates memory using malloc() but forgets to free it before exiting. What happens when this program runs? Can you use gdb to find any problems with it? How about valgrind (again with the --leak-check=yes flag)? 4. Write a simple program that allocates memory using malloc() but forgets to free it before exiting. What happens when this program runs?

Explanation / Answer

Theoretially, a memory leak occurs because of this behaviour. But most modern OS takes care to free the memory themselves.

no problems when doing gdb. Probably because the problem will come into notice when no/little free memory will be left for allocation.

part 3 : valgrind
