重载运算符

#include <bits/stdc++.h>
using namespace std;
struct Stu
{
    int a;
    string nam;
};
bool operator<(const Stu &a, const Stu &b)
{
    return a.a < b.a;
}
int main()
{
    int n;
    Stu a[105];
    cin >> n;
    for (int i = 1; i <= n; i++)
        cin >> a[i].a >> a[i].nam;
    Stu ans = a[1];
    for (int i = 1; i <= n; i++)
        if (ans < a[i])
            ans = a[i];
    cout << ans.nam;
    return 0;
}

使用两个数组

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n;
	int score[105];
	string name[105];

	cin>>n;
	for(int i=1;i<=n;i++)
		cin>>score[i]>>name[i];

	int max_score=-1;
	string max_name;
	for(int i=1;i<=n;i++)
	{
		if(score[i]>max_score)
		{
			max_score=score[i];
			max_name=name[i];	
		}	
	}
	
	cout<<max_name<<"\n";
	
	return 0;
}

使用结构体

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n;
	struct Student{
		int score;
		string name;
	};
	Student a[105];//a[0]~a[104] 都是 Student 

	cin>>n;
	for(int i=1;i<=n;i++)
		cin>>a[i].score>>a[i].name; //. -> 的 

	Student max_stu;
	max_stu.score = -1;
	for(int i=1;i<=n;i++)
		if(a[i].score>max_stu.score)
			max_stu = a[i];
	
	cout<<max_stu.name<<"\n";
	return 0;
}
