代码

#cat main.c
#include <stdio.h>

int add(int x, int y);
int sub(int x, int y);
int mul(int x, int y);
int div(int x, int y);

int main(void)
{
    printf("add:%d\n", add(1,2));
    printf("sub:%d\n", sub(10,100));
    printf("mul:%d\n", mul(5,10));
    printf("div:%d\n", div(200,100));

    return 0;
}

#cat math.c

int add(int x, int y)
{
    return (x + y);
}

int sub(int x, int y)
