Dangling Pointer in C

Question

I wrote a program in C having dangling pointer.

#include

int *func(void)
{
    int num;
    num = 100;
    return #
}

int func1(void         


        

Answer 1

It's undefined behavior. It could work correctly on your computer right now, 20 minutes from now, might crash in an hour, etc. Once another object takes the same place on the stack as num, you will be doomed!
