类似这种编程，求指点😥

Question

Answer 1

数组求和，乘以0.5就行了

#include <stdio.h>
int main()
{
    int n,m,i,j,sum = 0;
    scanf("%d",&n);
    for(i=0;i<n;i++) 
    {
        sum = 0;
        for(j=0;j<11;j++)
        {
            scanf("%d",&m);
            sum+=m;
        }
        printf("%.2f\n",sum*0.5);
    }
    return 0;
}
