输入三个实型数据，求最大值比平均数大多少。

Question

输入三个实型数据，求最大值比平均数大多少。 定义和调用函数Max（a，b，c）用来求最大值，Avg（a，b，c）用来求平均数。

Answer 1

#include <stdio.h>
 
double Max(double a,double b,double c);
double Avg(double a,double b,double c);
 
 
int main() {
    double a,b,c;
    printf("输入三个数，空格隔开:");
    scanf("%lf%lf%lf",&a,&b,&c);
    printf("最大值比平均值大%lf\n",Max(a,b,c) - Avg(a,b,c));
    return 0;
}
 
double Max(double a,double b,double c) {
    double max = a;
    if(max < b) max = b;
    if(max < c) max = c;
    return max;
}
 
double Avg(double a,double b,double c) {
    return (a + b + c)/3.0;
}
