【中文标题】C++ 中五子棋游戏的计算机播放器 [关闭]【英文标题】：Computer Player for a Gomoku Game in C++ [closed] 【发布时间】：2020-11-24 19:06:58 【问题描述】：前段时间我用 C++ 制作了一个类似于Gomoku 的游戏，需要两个玩家参与。
现在我想让它成为 Player vs Computer。 我尝试以最简单的方式做到这一点，通过使计算机功能来选择一个随机单元格，但我仍然没有成功。 我知道为了得到一个随机数，我可以使用 rand() 和这样的字母：
char letters[] = "abcdefghijklmnopqrstuvwxyz";
char x = letters[rand() % 26];
谁能帮我描述一下如何实现电脑播放器？ 这是我目前的实现：
#include <iostream>
#include <iomanip>
using namespace std;
void print_table(int x[][15])
system("cls");
for (int i = 0; i < 15; i++) //the loop that use to print out the english character row
if (i == 0)
cout << setw(4) << "A";
else if (i == 1)
cout << " B";
else if (i == 2)
cout << " C";
else if (i == 3)

for (int j = 0; j < 15; j++) //print out the board game.

【参考方案1】：以下是我可能会根据您的初始实现来实现它的方式：
#include <iostream>
#include <iomanip>
#include <cstdlib>
using namespace std;
#define SIZE 10
#define LINE_LENGTH 4
#define COMPUTER_O_PLAYER true
#define COMPUTER_X_PLAYER false

cout << " O";
cout << endl;
void get_position(int &x, int &y, bool player, unsigned char board[SIZE][SIZE])

请深入了解此实现并内化其方法，它还支持作为用户、用户和计算机的玩家，以及两者的计算机。
一些见解：
如果有更简单的方法，请不要使用长if ... else。
为变量使用正确的数据类型。
使用指示性变量命名。
尽可能使用循环，同样，不要太长if ... else。
保持代码格式正确。
使用#define 定义要使用的全局常量，以便以后更轻松地进行更改并提高可读性。
确实可以使用rand，但是不需要获取字符，直接获取索引就可以避免转换。

感谢 mate 让它变得更干净，但现在它没有读取一个玩家的输入:) 是的，我仍在尝试了解如何使其成为玩家与计算机））以上是关于C++ 中五子棋游戏的计算机播放器 [关闭]的主要内容，如果未能解决你的问题，请参考以下文章
