这个题目有点难度，帮帮忙

100<=T，没搞错吧
用%s%d%d%d%d%d接收每行数据，然后对整型求和后算平均值

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
    char buf[100];
    int num; // number of players
    scanf("%d", &num);

    for (int i = 0; i < num; i++) {
        int grade_total = 0;
        int grade;
        scanf("%s", buf);
        for (int j = 0; j < 5; ++j) {
            scanf("%d", &grade);
            grade_total += grade;
        }

        printf("%.2f\n", grade_total / 5.0);
    }
}

但没有14行就不行啊
