Question

从键盘输入三个整数，用C语言怎么编写一个简单程序求这三个数的和与平均值?

Answer 1

#include<iostream>
using namespace std;

long a,b,c;
double x;
int main()
{
cin>>a>>b>>c;
x=(a+b+c)/3;
cout<<x<<endl;
int cici;
cin>>cici;
return 0;
}

Answer 2

一楼,你写的是C++
#include<iostream.h>
int main()
{
long a,b,c;
double average;
while(scanf("%ld%ld%ld",&a,&b,&c)!=EOF)
{
average=(a+b+c)/3.0;
printf("average=%f\n",average);
}
}
