以下是test.c的代码

#include "game.h"

//测试三子棋游戏
void menu()
{
    printf("***********************\n");
    printf("****1.play   0.exit****\n");
    printf("***********************\n");
}
//游戏的整个算法实现
void game()
{
    char ret = 0;
    //数组 - 存放走出棋盘的信息
    char board[ROW][COL] = { 0 };//全部空格
    //初始化棋盘
    InitBoard(board, ROW, COL);
    //打印棋盘
    DisplayBoard(board,ROW,COL);
    //下棋
    while (1)
    {
        //玩家下棋
        PlayerMove(board, ROW, COL);
        DisplayBoard(board, ROW, COL);
        //判断玩家是否赢
        ret = IsWin(board, ROW, COL);
         if (ret != 'C')
         {
             break;
         }
        //电脑下棋
        ComputerMove(board, ROW, COL);
        DisplayBoard(board, ROW, COL);
        //判断电脑是否赢
        ret = IsWin(board, ROW, COL);
        if (ret != 'C')
        {
            break;
        }
    }
    if (ret == '*')
    {
        printf("玩家赢\n");
    }
    else if (ret == '#')
    {
        printf("电脑赢\n");
    }
    else
    {
        printf("平局\n");
    }
}
void test()
{
    int input = 0;
    srand((unsigned int)time(NULL));
    do
    {
        menu();
        printf("请选择:>");
        scanf("%d", &input);
        switch (input)
        {
        case 1:
            game();
            printf("三子棋\n");
            break;
        case 0:
            printf("退出游戏\n");
            break;
        default:
            printf("选择错误,请重新选择\n");
            break;
        }
    } while (input);
}
int main()
{
    test();
    return 0;
}

game.h的代码如下:

void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void ComputerMove(char board[ROW][COL],int row, int col);

//告诉我们四种游戏得状态
//玩家赢 - '*'
//电脑赢 - '#'
//继续   - 'Q'
//平局   - 'C'

char IsWin(char board[ROW][COL], int row, int col);

game.c的代码如下:

#include "game.h"

//返回1 表示棋盘满了
//返回0,表示棋盘没满
int IsFull(char board[ROW][COL], int row, int col)
{
    int i = 0;
    int j = 0;
    for ( i = 0; i < row; i++)
    {
        for ( j = 0; j < col; j++)
        {
            if (board[i][j] == ' ')
            {
                return 0;//没满
            }
        }
    }
    return 1;//满了
}
char IsWin(char board[ROW][COL], int row, int col)
{
    int i = 0;
    //横三行
    for ( i = 0; i < row; i++)
    {
        if (board[i][0] == board[i][1] && board[i][0] == board[i][2] && board[i][1] != ' ')
        {
            return board[i][1];
        }
    }
    //竖三列
    for ( i = 0; i < col; i++)
    {
        if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
        {
            return board[1][i];
        }
    }
    //两个对角线

        return board[1][1];
    if (board[2][0] == board[1][1] && board[1][1] == board[0][2] && board[1][1] != ' ')
        return board[1][1];
    //判断是否平局
    if (1 == IsFull(board,ROW,COL))
    {
        return 'Q';
    }
    return 'C';

    }
}

    printf("玩家走:>\n");
    //判断x,y坐标得合法性
    while (1)
