我代码轮着爆5、6

5号WA

#include<bits/stdc++.h>
using namespace std;
class people{
public:
	string name;
	int y,m,d;
};
bool operator<(people a,people b){
	if(a.y != b.y){
		return a.y < b.y;
	}else if(a.m != b.m){
		return a.m < b.m;
	}else if(a.d != b.d){
		return a.d < b.d;
	}
	return true;
}
int main(){
	int n;
	cin >> n;
	vector<people> num;
	for(int t = 0;t < n;t++){
		people temp;
		cin >> temp.name >> temp.y >> temp.m >> temp.d;
		num.push_back(temp);
	}
	sort(num.begin(),num.end());
	for(int t = 0;t < n;t++){
		cout << num[t].name << endl;
	}
	return 0;
}

6号测试点WA

#include<bits/stdc++.h>
using namespace std;
class people{
public:
	string name;
	int y,m,d;
};
bool operator<(people a,people b){
	if(a.y != b.y){
		return a.y < b.y;
	}else if(a.m != b.m){
		return a.m < b.m;
	}else if(a.d != b.d){
		return a.d < b.d;
	}
	return false;
}
int main(){
	int n;
	cin >> n;
	vector<people> num;
	for(int t = 0;t < n;t++){
		people temp;
		cin >> temp.name >> temp.y >> temp.m >> temp.d;
		num.push_back(temp);
	}
	sort(num.begin(),num.end());
	for(int t = 0;t < n;t++){
		cout << num[t].name << endl;
	}
	return 0;
}

不同之处：21、58行返回
