依旧全ACGO最正经题解

#include <iostream>
#include <algorithm>
using namespace std;
class student{
public:
    char name[25];
    int jin,yin,tong;
    int sum;
    void control_input(){
        cin>>name>>jin>>yin>>tong;
        sum = jin + yin + tong;
    }
    void control_output(){
        printf("%s %d %d %d %d\n",name,jin,yin,tong,sum);
    }
};
int main(){
    int n;
    cin>>n;
    student a[n];
    for(int i=0;i<n;i++)  a[i].control_input();
    for(int i=0;i<n;i++)  a[i].control_output();
    return 0;
}

当然，我猜很多人不会用class，所以你们可以把class替换成下列代码(这里就不写成员函数了，你们自己在main函数里输入输出)

struct student{
    char name[25];
    int jin,yin,tong;
    int sum;
};
