C is a function that returns a pointer to a local variable

Question

Consider the following code.

#include<stdio.h>
int *abc(); // this function returns a pointer of type int

int main()
{
    int *ptr;
    ptr = abc();
    printf("%d", *ptr);
    return 0;
}

int *abc()
{
    int i = 45500, *p;
    p = &i;
    return p;
}

Conclusion:

45500
