三子棋小游戏 - 博客

今天我们来写一个三子棋小游戏，主要运用的知识是函数调用，数组，循环等。

首先是棋盘菜单的打印：
void menu() { printf("**********************\n");
printf("**********************\n"); printf("**** 1.play ****\n"); printf("****
0.exit ****\n"); printf("**** made by wenbo****\n");
printf("**********************\n"); printf("**********************\n"); }
如果玩家玩完儿一局还想玩，可以再次进行，所以此时使用

do

{

}while()

来使这个游戏可以再次进行：
int main() { int input = 0; do { menu(); printf("请选择>"); scanf("%d", &input);
switch (input) { case 1: game(); break; case 0: printf("退出游戏\n"); break;
default: printf("选择错误，请重新输入！\n"); break; } } while (input); return 0; }
下一步，需要把棋盘给制作出来，如示意图：

由示意图可得代码：
void InitBoard(char board[ROW][COL], int row, int col) //制作棋盘，并且把每个空定义为空格 {
int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) {
board[i][j] = ' '; } } } void DisplayBoard(char board[ROW][COL], int row, int
col) //打印棋盘 { int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j <
col; j++) { printf(" %c ", board[i][j]); //打印数组中已经存放的元素 if (j != col - 1) {
printf("|");//在分隔处打印分隔线，最后列不需要打印 } } printf("\n"); if (i != row -
1)//在最后一行不需要打印分隔线 { int j = 0; for (j = 0; j < col; j++) { printf("---"); if (j
!= col - 1) { printf("|"); } } printf("\n"); } } }
此时，棋盘已经打印完毕，接下来就可以开始下棋了。这时我们要明白一个事情，就是必须没下一次棋，打印一次棋盘供玩家查看。代码如下：
void Player_move(char board[ROW][COL], int row, int col) //玩家下棋 { int x = 0;
int y = 0; while (1) { printf("请输入坐标\n"); scanf("%d %d", &x,&y); if (x >= 1 &&
x <= row && y >= 1 && y <= col) { if (board[x - 1][y - 1] == ' ') { board[x -
1][y - 1] = '*'; break; } else { printf("此坐标已被占用！\n"); } } else {
printf("坐标非法，重新输入！\n"); } } } void Computer_move(char board[ROW][COL], int row,
int col) //电脑下棋 { printf("电脑走\n"); while (1) { int x = rand() % row; int y =
rand() % col; //调用随机数值库函数 if (board[x][y] == ' ') { board[x][y] = '#'; break; }
} }
此时，如果哪一方首先取得了游戏的胜利，就可以结束游戏。

所以接下来应该设置比赛输赢的条件，如果完成条件，既可以结束游戏。

输赢条件和平局条件的判断：
char iswin(char board[ROW][COL], int row, int col) //判断输赢 { for (int i = 0; i
< row; i++) { if (board[i][1] == board[i][0] && board[i][1] == board[i][2] &&
board[i][1] == '*') return board[i][1]; if (board[i][1] == board[i][0] &&
board[i][1] == board[i][2] && board[i][1] == '#') return board[i][1];
}//判断水平的棋子是否相等 for (int j = 0; j < col; j++) { if (board[1][j] == board[0][j]
&& board[1][j] == board[2][j] && board[1][j] == '*') return board[1][j]; if
(board[1][j] == board[0][j] && board[1][j] == board[2][j] && board[1][j] ==
'#') return board[1][j]; }//判断纵行的棋子是否相等 if (board[1][1] == board[0][0] &&
board[1][1] == board[2][2] && board[1][1] == '*') return board[1][1]; if
(board[1][1] == board[0][0] && board[1][1] == board[2][2] && board[1][1] ==
'#') return board[1][1]; if (board[0][2] == board[1][1] && board[1][1] ==
board[2][0] && board[1][1] == '*') return board[1][1]; if (board[0][2] ==
board[1][1] && board[1][1] == board[2][0] && board[1][1] == '#') return
board[1][1]; //判断交叉的棋子是否相等 int ret = isdraw(board, ROW, COL); if (ret == 1)
return 'Q'; else return 'C'; } int isdraw(char board[ROW][COL], int row, int
col) { for (int i = 0; i < row; i++) { for (int j = 0; j < col; j++) { if
(board[i][j] == ' ') { return 0; } } } return 1; }
