易懂c++代码

这道题运用结构体存储学员数据，按要求计算各自奖学金，并输出要求的数据
写时有点费脑子
代码如下（最朴实易懂的写法）：

#include<iostream>
#include<algorithm>
using namespace std;
int n, sum;
struct people{
    string name;
    int cas;
    int cs;
    char st, west;
    int w, j, mo;
}a[101];
bool cmp(people a, people b){
    if(a.j == b.j){
        return a.mo < b.mo;
    }
    return a.j > b.j;
}
int main(){
    cin >> n;
    for(int i = 0; i < n; i++){
        cin >> a[i].name >> a[i].cas >> a[i].cs >> a[i].st >> a[i].west >> a[i].w;
        a[i].mo = i;
        if(a[i].cas > 80 && a[i].w >= 1){
            a[i].j += 8000;
        }
        if(a[i].cas > 85 && a[i].cs > 80){
            a[i].j += 4000;
        }
        if(a[i].cas > 90){
            a[i].j += 2000;
        }
        if(a[i].cas > 85 && a[i].west == 'Y'){
            a[i].j += 1000;
        }
        if(a[i].cs > 80 && a[i].st == 'Y'){
            a[i].j += 850;
        }
        sum += a[i].j;
    }
    sort(a, a + n, cmp);
    cout << a[0].name << endl;
    cout << a[0].j << endl;
    cout << sum;
    return 0;
}
