能搞个机翻吗，或者题目文字贴出来

第二个代码

#include<stdio.h>

float pj(int a,int b, int c)
{
    return (a+b+c)/3.0;
}
int cj(int a,int b, int c)
{
    return a*b*c;
}
int main()
{
    int a,b,c;
    printf("请输入三个数字：");
    scanf("%d%d%d",&a,&b,&c);
    printf("平均值%.2f\n",pj(a,b,c));
    printf("乘积%d\n",cj(a,b,c));

    return 0;
}

是算x(t)吗？
