从键盘输入100个整数，统计其中偶数的平均值

输入100个多累啊，

#include <iostream>
using namespace std;
void main()
{
int a[100];
int sum=0;
int count=0;
cout<<"input the data:"<<endl;
for(int i=0;i<100;i++)
{
cin>>a[i];
if(a[i]%2==0)
{sum+=a[i];
count++;
}
}
cout<<"the average is: "<<float(sum)/count<<endl;
}

楼上的cout<<"the average is: "<<float(sum)/count<<endl; 此条语句应该改为cout<<"the average is: "<<（float）sum/（float）count<<endl;

用C语言，实现起来很简单，这是我写的——

#include <stdio.h>
main()
#define N 100
{
int a[100],b=0,i,sum=0; float aver;

printf ("Please input %d numbers:\n",N);
for (i=0;i<N;i++)
{scanf ("%d",&a[i]);
if (a[i]%2==0) {sum=sum+a[i]; b++;} }

aver=sum/b;

printf ("There
