结构体 + cmp定义 （可能看起来好看些）

#include <bits/stdc++.h>
#define int long long int

using namespace std;

const int N = 310;
struct node{
    int c,m,e,id;//chinese,math,english
    int sum;
}s[N];
int n;

bool cmp(node a1,node a2){
    if(a1.sum != a2.sum) return a1.sum > a2.sum;
    if(a1.c != a2.c) return a1.c > a2.c;
    return a1.id < a2.id;
}

signed main(){
    scanf("%lld",&n);
    for (int i = 1;i <= n;i ++){
        scanf("%lld %lld %lld",&s[i].c,&s[i].m,&s[i].e);
        s[i].id = i;
        s[i].sum = s[i].c + s[i].m + s[i].e;
    }
    sort(s + 1,s + 1 + n,cmp);
    for (int i = 1;i <= 5;i ++){
        printf("%lld %lld\n",s[i].id,s[i].sum);
    }
    return 0;
}
