来自C++新手的另一个问题.

我收到编译器错误"不匹配'运算符=='"以获取以下代码块

void swap(Team t1, Player p1, Team t2, Player p2){
    Player new_t1[11];
    Player new_t2[11];
    for(int i=0; i<11; i++){
        new_t1[i] = t1.get_player(i);
        new_t2[i] = t2.get_player(i);
        if(new_t1[i] == p1){
            new_t1[i] = p2;
        }
        if(new_t2[i] == p2){
            new_t2[i] = p1;
        }
    }

    cout << "Players swapped.";
}

有任何想法吗？

我是C++的新手,我正在尝试编写一个模拟足球比赛的程序.我收到一个编译器错误,指出函数get_rank,get_player和get_name未在此范围内声明.任何帮助是极大的赞赏!

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

class Player {
    int playerNum;
    string playerPos;
    float playerRank;
    public:
        void set_values(int, string, float);
        float get_rank(){ return playerRank; };
};

class Team {
    Player team[];
    string teamName;
    public:
        void set_values(Player[],string);
        Player get_player(int a) { return team[a]; };
        string get_name() { return teamName; };
};


void play(Team t1, Team t2){
    float t1rank = 0.0;
    float t2rank = 0.0;
    for(int i=0; i<11; i++){
        t1rank += get_rank(get_player(t1, i));
    }
    for(int j=0; j<11; j++){ …
