打印棋盘1

//存放下棋数据

//初始化棋盘为全空格

//初始化棋盘为空格
void InitBoard(char board[ROW][COL], int row, int col)

}

玩家下棋1

//玩家下棋
void player_move(char board[ROW][COL], int row, int col)

电脑下棋1

void computer_move(char board[ROW][COL], int row, int col)
{int x = 0;int y = 0;printf("电脑下棋：>\n");while (1){x = rand() % 3;//范围（a，b）用rand表示就是rand（）%（b-a+1）y = rand() % 3;if (board[x][y] == ' ')//判断是否为空格，因为只有这一个条件，所以满足这个条件就可以下{board[x][y] = '#';break;}}
}

判断输赢1

while (1)//玩家和电脑轮流下棋，直到一方胜利{   //玩家下棋player_move(board, ROW, COL);//打印棋盘DisplayBoard(board, ROW, COL);ret = is_win(board, ROW, COL);if (ret != 'C'){break;}//电脑下棋computer_move(board, ROW, COL);//打印棋盘DisplayBoard(board, ROW, COL);ret = is_win(board, ROW, COL);if (ret != 'C'){break;}}if (ret == '*'){printf("玩家获胜\n");}else if (ret == '#'){printf("电脑获胜\n");}else // (ret == 'Q'){printf("平局\n");}DisplayBoard(board, ROW, COL);
