三子棋（微智能）

Posted 2020-11-10

今天总结了这一段时间来的学习，写了一个三子棋的程序，纯C语言的小游戏，简单易写，这也花了我两三天时间，整个程序主要分为：测试程序test.c,游戏程序game.c,头文件引用game.h;主要的函数有：初始化棋盘 void init_board，打印棋盘print_board，玩家移动player_move，电脑移动computer_move，判断是否有胜利IsWin，判断棋盘是否满了IsFull；
话不多说，上代码

test.c

printf("*************************\n");

printf("*************************\n");

}

char arr[row][col] = {0};
char ret = 0;
srand((unsigned int)time(NULL));
//初始化棋盘
init_board(arr, row, col);
print_board(arr, row, col);
while (1) {
    player_move(arr,row,col);
    ret = IsWin(arr, row, col);
    if (ret != ‘C‘)
    break;
    print_board(arr, row, col);

    computer_move(arr, row, col);
    ret = IsWin(arr, row, col);
    if (ret != ‘C‘)
    break;
    print_board(arr, row, col);
