Question

What situation has occurred after the last assignment of the following code?

int *p = malloc(sizeof(int));

*p = 400;

p = NULL;

Answer 1

Hello!

Patrick is absolutely right, this is a memory leak.

I explain in the video above, but essentially:

Just because p no longer points to the memory given to it by malloc(), does not mean that memory was "freed". This means that when you say p = NULL, you're saying p no longer points to that memory, but that memory still exists. However, it is no longer accessible (leaked memory).

Answer 2

Memory leak

the memory was allocated but did not get freed
