What should be printed by the code below? One compiler I used printed

reached f1
reached f2
2

Another printed

reached f2
reached f1
2

Which one is right? Here's the code:

Code:

#include <stdio.h>

short f1(){
    printf("reached f1\n");
    return (1);
}
short f2(){
    printf("reached f2\n");
    return (2);
}

void main(){
    short x;
    x = f1() * f2();
    printf("%d\n",x);
}
