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

With dangling pointers, the result of a program is undefined. It depends on how the stack and the registers are used. With different compilers, different compiler versions and different optimization settings, you'll get a different behavior.
