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

求助但是不要给题解，指出错误即可，谢谢
