示例代码：

#include <stdio.h>

int min(const int m, const int n);

int max(const int m, const int n) {
    if (m > n) {
        return m;
    }

    return n;
}

int sum(const int m, const int n) {
    return m + n;
}

int diff(const int m, const int n) {
    return m - n;
}

int product(const int m, const int n) {
    return m * n;
}

int main() {
    int m = 0;
    int n = 0;

    scanf("%d", &m);
    scanf("%d", &n);

    printf("min: %d\n", min(m, n));
    printf("max: %d\n", max(m, n));
    printf("sum: %d\n", sum(m, n));
    printf("diff: %d\n", diff(m, n));
    printf("product: %d\n", product(m, n));

    return 0;
}

int min(const int m, const int n) {
    if (m > n) {
        return n;
    }
    return m;
}
