c语言图形化界面五子棋的具体代码

以下是一个使用Windows API实现的C语言图形化界面五子棋游戏的代码示例：

#include <windows.h>

// 窗口宽度和高度
#define WINDOW_WIDTH 640
#define WINDOW_HEIGHT 640

// 棋盘格子数量
#define GRID_NUM 15

// 棋盘格子宽度和高度
#define GRID_WIDTH (WINDOW_WIDTH / GRID_NUM)
#define GRID_HEIGHT (WINDOW_HEIGHT / GRID_NUM)

// 棋子大小
#define PIECE_SIZE (GRID_WIDTH / 2 - 2)

// 棋子颜色
#define PIECE_COLOR_BLACK RGB(0, 0, 0)
#define PIECE_COLOR_WHITE RGB(255, 255, 255)

// 窗口句柄
HWND g_hwnd = NULL;

// 棋盘数组
int g_board[GRID_NUM][GRID_NUM] = {0};

// 当前玩家，1表示黑方，2表示白方
int g_current_player = 1;

// 电脑AI难度，0表示简单，1表示困难

// 电脑AI下棋

这段代码使用了Windows API来创建窗口和处理鼠标点击事件等消息，实现了一个简单的五子棋游戏。具体实现细节可以参考代码注释。
