AC代码：

#include<iostream>
#include<algorithm>
using namespace std;
struct node{
    int yuwen;
    int sum;
    int id;
    //不定义数学与英语成绩,因为它们不参与到名次的高低问题
}a[100001];
int n,shuxue,yingyu;
int cmp(node x,node y){
    if(x.sum!=y.sum){
        return x.sum>y.sum;//总分大优先
    }
    if(x.yuwen!=y.yuwen){
        return x.yuwen>y.yuwen;//语文大优先
    }
    if(x.id!=y.id){
        return x.id<y.id;//学号小优先
    }
}
int main()
{
    cin>>n;
    for(int i=1;i<=n;i++){
        cin>>a[i].yuwen>>shuxue>>yingyu;
        a[i].sum=a[i].yuwen+shuxue+yingyu;//处理总分
        a[i].id=i;//处理学号
    }
    sort(a+1,a+n+1,cmp);
    //输出前5名
    for(int i=1;i<=5;i++){
        cout<<a[i].id<<" "<<a[i].sum<<endl;
    }
    return 0;
}

你最后一个循环的范围写错了

by xueshengyi @ 2023-12-24 18:03:29

应该是

i=1;i<=5;i++
