Thread: Return a pointer to a variable declared inside the function (basic question)

** sorry, this is a basic question, but couldn't find the answer on Google **

In the following code, is it guaranteed that the "number" variable will point to the same value as assigned in the "f" function? Because I have the idea that "n" will be destroyed, so "i" will point to a random place, but when I run this code, it prints the right value.

Code:

#include <stdio.h>

int *f() {
    int *i;
    int n = 15;
    i = &n;
    return i;
}

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