包含类的 C++ 排序列表

Question

我有一个小问题。我目前正在编写一个用于处理锦标赛的代码，我想出一个想法，即让团队在内存中保持有序的最佳方法是列表。 现在，我正在尝试对包含点记录的列表进行排序。 这是类声明：

#include "player.h"
#include <string>

class Team {
Player** Gracz;
std::string Name;
int TP, STP;
int Total;

public:
Team();
Team(Player* gracz1, Player* gracz2, Player* gracz3, Player* gracz4, Player*     gracz5, Player* gracz6, std::string name);
~Team();

void SetTeam();
void SetTeam(Player gracz1, Player gracz2, Player gracz3, Player gracz4, Player gracz5, Player gracz6, std::string name);
void SetTP(int tp);
void SetSTP(int stp);

std::string GetTeam();
int GetTotal();
int GetTP();
int GetSTP();

bool operator<(Team& team);
bool operator>(Team& team);

void PrintTeam();
};

这是程序代码：

#include <iostream>
#include "player.h"
#include "team.h"
#include <list>
#include <string>

using namespace std;

int main(int argc, char *argv[]) {
Player *p;
Team *t1, *t2, *t3, *t4;
list<Team> x;
list<Team>::iterator it;

p=new Player("a","a","a");

t1=new Team(p,p,p,p,p,p,"A");
t2=new Team(p,p,p,p,p,p,"B");
t3=new Team(p,p,p,p,p,p,"C");
t4=new Team(p,p,p,p,p,p,"D");

x.push_back(*t1);
x.push_back(*t2);
x.push_back(*t3);
x.push_back(*t4);

cout<<"Turniej: "<<endl;
for(it=x.begin();it!=x.end();++it)
    cout<<" "<<(*it).GetTeam();
cout<<endl;

t1->SetTP(15);
t2->SetTP(4);
t3->SetTP(8);
t4->SetTP(8);
t3->SetSTP(15);
t4->SetSTP(65);

x.sort(); 

cout<<"Turniej: "<<endl;
for(it=x.begin();it!=x.end();++it)
    cout<<" "<<(*it).GetTeam();
cout<<endl;

return 0;
}

所以我想先按 TP 排序，然后按 STP 排序，它包含在重载运算符

感谢您的帮助。

这里对象被复制，它的副本被推送到容器中：

x.push_back(*t1);
/* the same for others */

这里修改了原来的对象，但是容器中的副本不变：

t1->SetTP(15);
