Question

编写一个C++程序，通过键盘输入三个整数，打印其和以及平均值。

输出信息 Input three different integer: 13. 27 .14
Sum is 54
Average is 18

Answer 1

#include<stdio.h>

int main() 

{

int a,b,c,s;

printf("请输入三个整数:");

scanf("%d%d%d",&a,&b,&c);

s=a+b+c;

printf("%d+%d+%d=%d\nav=%f\n",a,b,c,s,s/3.0);

getch();

return 0;

}

Answer 2

这么简单还问，找班上学习差不多的都会
#include<stdio.h>
int main()
{
int a,b,c,sum,Average;
printf("Input three different integer:");
scanf("%d",&a);
scanf("%d",&b);
scanf("%d",&c);
sum=a+b+c;
Average=sum/3;
printf("Sum is %d \n",sum);
printf("Average is %d \n",Average);
return 0;
}

Answer 3

#include<iostream>
using namespace std;
int main()
{
int num1,num2,num3;//定义三个整数
cin>>num1>>num2>>num3;//输入三个整数
cout<<"Input three different integer: <<num1<<"."<<num2<<"."<<num3<<endl;
cout<<"sum is "<<(num1+num2+num3)<<endl;//输入和
cout<<"Average is "<<(num1+num2+num3)/3;//输出平均数
return 0;
}

Answer 4

#include<iostream>
using namespace std;
int main()
{
int num1,num2,num3;
int sum,average;

cout<<"Input three different integer: ";
cin>>num1;//如13
cout<<".";

cin>>num2;//如27
cout<<".";

cin>>num3;//如14
cout<<".";

sum=num1+num2+num3;
average=sum/3;

cout<<"Sum is "<<sum<<endl;
cout<<"Average is "<<average<<endl;

}
