利用结构体sort排序，在用条件语句判断

#include<stdio.h>
#include<algorithm>
#include<string>
#include<vector>
#include<iostream>
using namespace std;
int n;
struct cj
{
	string name;
    int grade;
}s[1000];
int cmp(cj a,cj b)
{
	return a.grade>b.grade;
}
int main()
{
    scanf("%d",&n);
    for(int i=0;i<n;i++)
    {
        cin>>s[i].name>>s[i].grade;
    }
    sort(s,s+n,cmp);
    for(int i=0;i<n;i++)
    {
        if(s[i].grade>=1&&s[i].grade<200)
        {
            cout<<s[i].name<<" "<<s[i].grade<<" "<<"Not good"<<endl;
        }else if(s[i].grade>=200&&s[i].grade<300)
        {
            cout<<s[i].name<<" "<<s[i].grade<<" "<<"Bronze medal"<<endl;
        }else if(s[i].grade>=300&&s[i].grade<400)
        {
            cout<<s[i].name<<" "<<s[i].grade<<" "<<"Silver medal"<<endl;
        }else if(s[i].grade>=400)
        {
            cout<<s[i].name<<" "<<s[i].grade<<" "<<"Gold medal"<<endl;
        }else cout<<s[i].name<<" "<<s[i].grade<<" "<<"Bad"<<endl;
    }
    return 0;
