C++ 五子棋人机对战代码

五子棋是一种非常经典的棋类游戏。在网络上，很多玩家会选择人机对战的方式来进行游戏。C++语言作为一种非常高效的编程语言，也可以用来开发五子棋人机对战的代码。

以下是一份C++五子棋人机对战代码，供感兴趣的读者学习与参考：


#include <iostream>
#include <stdlib.h>
#include <string.h>
using namespace std;
const int SIZE = 15; // 表示棋盘大小为15*15
const int WIN_NUM = 5; // 表示一条线上连续的五个棋子获胜
// 定义棋盘
enum ChessMan
  EMPTY;
struct ChessBoard {
  ChessMan point[SIZE][SIZE];
};
// 定义位置
struct Point {
  int x;
  int y;
  Point(int x = 0, int y = 0): x(x), y(y) {}
};
// 定义游戏状态
enum GameStatus
  DRAW
;
// 初始化棋盘
void InitBoard(ChessBoard& board) {
  for (int i = 0; i < SIZE; i++) {
    for (int j = 0; j < SIZE; j++) {
      board.point[i][j] = EMPTY;
    }
  }
}
// 打印棋盘
void PrintBoard(const ChessBoard& board) {
  for (int i = 0; i < SIZE; i++) {
    for (int j = 0; j < SIZE; j++) {
      switch (board.point[i][j])
        case EMPTY:
          cout << ".";
          break;
        case BLACK:

          break;

// 人类下棋

}

这份代码实现了一个五子棋人机对战的简单版本。当程序运行后，它会先打印出一个初始的棋盘，然后人类玩家会以黑色棋子开始下棋，接着电脑会以白色棋子回应，双方轮流下棋，直到出现一方获胜或者平局，最后程序会显示结果并退出。

这份代码实现了五子棋的基本规则，但是也有很多可以改进的地方。比如，电脑下棋的算法还有优化的空间，比如使用更智能的遍历算法。另外，该程序还没有实现图形界面，如果想要让用户能够通过更直观的视觉效果来体验游戏，就需要更深入地了解C++的图形界面编程。
