c语言 三子棋

以下是一个简单的 C 语言三子棋游戏示例：

#include <stdio.h>

// 定义棋盘大小
#define BOARD_SIZE 3

// 定义棋子类型
#define EMPTY 0
#define PLAYER1 1
#define PLAYER2 2

// 定义玩家类型
#define HUMAN 1
#define COMPUTER 2

// 定义函数声明
void initialize_board(int board[][BOARD_SIZE]);
void print_board(int board[][BOARD_SIZE]);
int make_move(int board[][BOARD_SIZE], int row, int col, int player);
int get_winner(int board[][BOARD_SIZE]);
int get_move(int board[][BOARD_SIZE], int player);
int check_move(int board[][BOARD_SIZE], int row, int col);

// 主函数
int main() {

    // 初始化棋盘
    initialize_board(board);
    
    // 游戏循环
    while (winner == 0) {
        // 打印棋盘
        print_board(board);

}

// 获取玩家移动
int get_move(int board[][BOARD_SIZE], int player) {
    // todo: 实现计算机 AI
}

// 检查移动是否合法
int check_move(int board[][BOARD_SIZE], int row, int col) {
    if (row >= 0 && row < BOARD_SIZE && col >= 0 && col < BOARD_SIZE && board[row][col] == EMPTY) {

    }
    else {
        return 0;
    }
}

这只是一个简单的示例，计算机 AI 部分需要进行更复杂的实现。
