c++ - 在不使用指针的情况下在 C++ 中将数组作为引用传递

Question

我有一个关于我必须完成的 C++ 作业的快速问题。老师要求我包含以下功能:

void getPlayerInfo(Player &);
void showInfo(Player);
int getTotalPoints(Player [], int);

但是我在处理第一个函数时遇到了问题....我不确定我是否正确地调用了结构数组。有人可以查看一下，看看我做错了什么吗？我稍微摆弄了一下，我能够调用数组并传递一个指向数组的指针，但老师要求“&”符号在那里，所以一定有另一种我不知道的方法。请帮忙!谢谢

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;

// Structure to hold information about a player
struct Player
{
    string name;        // to hold the players name
    int number;         // to hold players number
    int points;         // to hold the points scored by the player
};

// Function prototypes
void getPlayerInfo(Player &); // function to get the players information       from the user
void showInfo(Player);    // function to show the table

int main()
{
    const int numPlayers = 12;  // Constant to hold the number of players
    Player team[numPlayers];    // array to hold 12 structures

                            // Gather information about all 12 players
    getPlayerInfo(team);

    showInfo(team);


    return 0;
}

// Function to get the players info
void getPlayerInfo(Player& team)
{
   for (int count = 0; count < 12; count++)
{
    cout << "PLAYER #" << (count + 1) << endl;
    cout << "----------" << endl;
    cout << "Player name: ";
    cin.ignore();
    getline(cin, team[count].name);
    cout << "Player's number: ";
    cin >> team[count].number;
    cout << "Points scored: ";
    cin >> team[count].points;
    cout << endl;
}

getPlayerInfo() 不接受数组，它接受对单个 Player 对象的引用。

您需要为数组中的每个玩家调用 getPlayerInfo()。将循环从 getPlayerInfo() 移到 main() 中。
