题目

代码如下：

#include<bits/stdc++.h>
using namespace std;
int n;
struct stu//结构体
{
    int num;
    int c,m,e;
    int sum;
}student[310];
bool cmp(stu a,stu b)
{
    if(a.sum>b.sum)return 1;
    else if(a.sum<b.sum)return 0;
    else
    {
        if(a.c>b.c)return 1;
        else if(a.c<b.c)return 0;
        else
        {
            if(a.num>b.num)return 0;
            else return 1;
        }
    }
}
int main(){
   cin>>n;
   for(int i=1;i<=n;i++)
   {
    student[i].num=i;
    cin>>student[i].c>>student[i].m>>student[i].e;
    student[i].sum=student[i].c+student[i].m+student[i].e;

   }
   sort(student+1,student+n+1,cmp);//排序
   for(int i=1;i<=5;i++)cout<<student[i].num<<" "<<student[i].sum<<endl;
return 0;
}
