@7546391a 我也不知道为什么你的写法会WA，但是好像 cmp 写的不太对。

//我的代码
#include <iostream>
#include <algorithm>
using namespace std;

struct peo{
    int ch,ma,en;
    int mark;
    int id;
} a[305];

bool cmp(peo x,peo y){
    if (x.mark > y.mark) return 1;
    else if (x.mark < y.mark) return 0;
    else{
        if (x.ch > y.ch) return 1;
        else if (x.ch < y.ch) return 0;
        else{
            if (x.id > y.ch) return 0;
            else return 1;
        }
    }
}
int main(){
    int n;
    cin>>n;
    for (int i = 1;i <= n;i++){
        cin>>a[i].ch>>a[i].ma>>a[i].en;
        a[i].mark = a[i].ch + a[i].ma + a[i].en;
        a[i].id = i;
    }
    sort(a + 1,a + n + 1,cmp);
    for (int i = 1;i <= 5;i++){
        cout<<a[i].id<<" "<<a[i].mark<<endl;
    }
}

输入的时候语文和英语写反了

@7546391a 这道题的排序还与语文成绩有关，具体再读题 你WA的两个点都与此有关
