A prototype tells the compiler a function's signature before its body appears.

Solution explanation

Prototypes let you put main first and still call functions defined later.

#include <stdio.h>

int max2(int a, int b);

int main() {
    int a, b, c;
    scanf("%d %d %d", &a, &b, &c);
    printf("%d\n", max2(max2(a, b), c));
    return 0;
}

int max2(int a, int b) {
    return a > b ? a : b;
}
