精C++结构体 用法

#include<bits/stdc++.h>
using namespace std;
struct student{
	int no;
	string name;
	double born;
};
int n;
student s;
vector<student> v;
bool cmpBorn(student s1,student s2){
	return s1.born >s2.born ;
}
bool cmpNo(student s1,student s2){
	return s1.no < s2.no  ;
}
int main(){
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>s.no >>s.name >>s.born ;
		v.push_back(s) ;
	}
	//先排优先级低的，后排优先级高 
	sort(v.begin(),v.end(),cmpNo);
	sort(v.begin(),v.end(),cmpBorn);
	for(int i=0;i<v.size();i++){
		cout<<v[i].no<<" "<<v[i].name<<" "<<v[i].born<<endl;
	}
	return 0;
}
