c++读入一批正整数（最多100个），输出它们的平均值。（用const定义常量）程序填空
测试通过
#include <stdio.h>
const int N = 100;
int a[N];
int main()
{
int cnt = 0;
double s = 0.0;
for (int i = 0; i < N && scanf("%d", &a[i]); i++, cnt++)
s += a[i];
printf("%f\n", s / double(cnt));
return 0;
}
#include <stdio.h>
const int N=100;
int a[N];
int main()
{
int cnt=0;
double s=0.0;
for (int i=0;i<N&&scanf("%d",&a[i]);i++,cnt++)
s+=a[i];
printf("%08.2f",s/double(cnt));
return 0;
}
#include <stdio.h>

double s=0.0;
