@lr0818 a数组是什么类型？s类型！下面的代码就可以

#include <bits/stdc++.h>
using namespace std;
const int N=307;
struct s{
    int a,e;
    long long d;
} a[N];
bool cmp(s x, s y) {
    if (x.e!=y.e)   return x.e>y.e;
    if (x.a!=y.a)   return x.a>y.a;
    return x.d<y.d;
}
int main() {
    long long n,b,c;
    cin >> n;
    for (int i = 1; i <= n; i++) {
        cin>>a[i].a>>b>>c;
        a[i].d=i;
        a[i].e=a[i].a+b+c;
    }
    sort(a+1,a+n+1,cmp);
    for (int i = 1; i <= 5; i++) {
        cout<<a[i].d<<" "<<a[i].e<< "\n";
    }
    return 0;
}

@lr0818

不是，哥们？

return x.d<x.d;
