C++ 飞镖项目未发送分数显示

Question

我正在尝试用 C++ 编写一个面向对象的 501 飞镖游戏，我已经设置了所有功能，但是当我运行该程序时，尽管没有错误消息，但它不显示玩家的分数。显然我编写了一个逻辑错误，但我正在努力调试它。

Player类头文件：

#pragma once 
#include <string>

using namespace std;

class player
{
private:
    string playername;
    int hitrate;
    int score;
    bool won;

public:
    void setup_playername(string newplayername)
    {
        playername = newplayername;
    }

    void setup_hitrate(int newhitrate)
    {
        hitrate = newhitrate;
    }

    void setup_score(int newscore)
    {
        score = newscore;
    }

    void setup_won(int newwon)
    {
        won = newwon;
    }
};

C++ 文件代码：

#include <iostream>
#include <cstdlib>
#include <time.h>

    joe.setup_playername("Joe");
    joe.setup_hitrate(joerate);
    joe.setup_score(joescore);
    joe.setup_won(joewon);

    player sid;

    return 0;
}

我尝试在代码中添加断点来找出问题所在，但我没有找到问题所在。我尝试过手动向程序插入固定分数，看看这是否是我的飞镖投掷的问题，但这也不起作用。

Answer 1

main() 是一个特殊函数。你不能像这样简单地添加参数。

它总是这样

int main(int argc, char *argv[])
{
   return 0;
}

要从命令行将参数传递给 main，您需要迭代数组 argv，其中包含 argc 条目数。
