4.电脑输入
电脑输入这里我们将引用前面猜数字游戏所讲的一个知识点，随机数的产生，接下来我们来看看代码的实现
void ComputerMove(char board[ROW][COL], int row, int col) { printf("电脑输入\n"); while (1)//循环输入，直到输入成功为止 { int x = rand() % row;//与前面所讲的srand()一起使用，可产生1-row的随机数 int y = rand() % col;//1-col的随机数 if (board[x - 1][y - 1] == ' ') { board[x - 1][y - 1] = '#';//电脑下棋落子记为'#' break;//输入成功跳出循环 } } }
结果展示可以参考上一张图
5.判断输赢
数据输入了进来，这时候我们就要进行判断游戏是否继续，如果不继续结果是怎么样的？
代码如下：
char IsWin(char board[ROW][COL], int row, int col) { //赢 //行 int i = 0; for (i = 0; i < row; i++) { if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ') { return board[i][0];//返回赢得棋子是*还是# } } //列 for (i = 0; i < col; i++) { if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ') { return board[0][i];//返回赢得棋子是*还是# } } //对角线 if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') return board[1][1];//返回赢得棋子是*还是# if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') return board[1][1];//返回赢得棋子是*还是# //平局 if (IsFull(board, row, col) == 1) { return 'Q'; } //继续 return 'C'; }
这个函数里还嵌套了一个IsFull()得函数，用来判断是否所有空格都被填满，代码如下
int IsFull(char board[ROW][COL], int row, int col) { int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) { if (board[i][j] == ' ') return 0; } } return 1; }
到此为止所有需要得功能都已经写完，接下来我们要将他们组装起来，组装如下
void game() { char board[ROW][COL] = { 0 }; InitBoard( board, ROW, COL);//数组初始化 DisplayBoard(board, ROW, COL);//打印最初得棋盘 while (1) { PlayerMove(board, ROW, COL);//玩家输入 DisplayBoard(board, ROW, COL);//打印已经改变的棋盘 if (IsWin(board, ROW, COL) != 'C')//判断是否继续游戏 break;//游戏结束跳出循环 ComputerMove(board, ROW, COL);//电脑输入 DisplayBoard(board, ROW, COL);//打印改变得棋盘 if (IsWin(board, ROW, COL) != 'C')//判断是否继续游戏 break; } if (IsWin(board, ROW, COL) == '*') printf("恭喜你，你赢了！！\n");//接受返回值做出判断 if (IsWin(board, ROW, COL) == '#') printf("很遗憾，你输了！！\n");//接受返回值做出判断 if (IsWin(board, ROW, COL) == 'Q') printf("平局！！\n");//接受返回值做出判断 }
至此呢，所有代码都已完成，我们来试玩一下
成功实现，但是我们发现，前面堆积太多了，下一次游戏进行十分不美观，这时候博主前面所讲得一个就起作用了 ，有了这一段代码后，只需要你再按一下回车，就可以清除前面所打印的。
以上就是博主的对三子棋游戏的实现，制作不易，各位看官给个三连呗！！！
