c++ - 创建飞镖游戏并出现两个错误 "too few argurments in function call"和 "game, identifier not found"

Question

创建飞镖游戏并出现两个错误

too few argurments in function call

和

game, identifier not found

我正在尝试为一项任务创建一个游戏，让两个玩家“joe 和 sid”从 301 开始玩飞镖，没有 double ，只有公牛和数组中的 21 个数字，解决问题的任何帮助都是非常感谢，下面的代码有四个主要功能，每个功能都会降低分数，首先是 50 分(公牛)，然后是 20 分，然后是单打，当分数达到 50 时，两名球员必须以公牛和任何不是公牛的分数结束, 被丢弃。

下面是我的代码，如有任何帮助，我们将不胜感激。

#include <iostream>
using namespace std;

int dartScores[] = {20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, 5, 20};

void makeThrow( int &score );

int main () 
{
    int joeScore = 301;
    int sidScore = 301;

    for (int i = 0; i< 1000;i++){
    while( joeScore > 0 || sidScore > 0 )
    {
        //do a throw
        game( joeScore);
        game( sidScore);

    }
    // remember to reset the score value

    }


}
void makeThrow_50( int &score, int acc )
{
    if ( rand()%100 < acc )
    {
        score -= 50;
    }
    else
    {
        //select a random
        int missedScore = dartScores[ rand()%20 ];

        // Only reduce score when thrown score is less than remaining score
        if (missedScore > score)
        {
            // Valid dart, take from score
            score -= missedScore;
        }

Answer 1

1. 您需要申报 game在 main 之前
2. game函数有 2 个参数，而您只传递一个参数(在 main 中)
3. 你需要#include <cstdlib>对于 rand() .
4. 我也建议 #include <time.h>并放置 srand (time(NULL))在main的开头.
