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

Returning a pointer to a local variable yields undefined behaviour, which means that anything the program does (anything at all) is valid. If you are getting the expected result, that's just dumb luck.
