Solution :

#include <stdio.h>

int maximum(int a, int b)
{
    if (a > b) {
        return a;
    } else {
        return b;
    }
}

int main(void)
{
    int x = 15, y = 23, z = 8;

    int max = maximum(maximum(x, y), z);

    printf("Le maximum de %d, %d et %d est %d\n", x, y, z, max);

    return 0;
