return y.xh < x.xh;

改成

return x.xh < y.xh;

因为学号越小越靠前

你自己看看AC代码：

#include<bits/stdc++.h>
using namespace std;
int n;
struct node{
    int c,m,e,id,sum;
};
node a[10005];
bool cmp(node x,node y){
    if(x.sum>y.sum) return true;
    else if(x.sum<y.sum) return false;
    else{
        if(x.c>y.c) return true;
        else if(x.c<y.c) return false;
        else{
            return (x.id<y.id);
        }
    }
}
int main(){
    cin>>n;
    for(int i=1;i<=n;i++){
        cin>>a[i].c>>a[i].m>>a[i].e;
        a[i].sum=a[i].c+a[i].e+a[i].m;
        a[i].id=i;
    }
    sort(a+1,a+1+n,cmp);
    for(int i=1;i<=5;i++) cout<<a[i].id<<" "<<a[i].sum<<"\n";
    return 0;
}
