棋盘样式
棋盘是三行，三列，就可以看成一个二维数组board[3][3].
三子棋首先需要创建二维数组并初始化，初始化为一个空格，然后将初始值和分割线打印出来就可以打印棋盘的样式。
游戏规则
- 用户和电脑玩游戏，用户下棋位置由用户输入（1，1)表示第一行第一列位置，行数范围1-3，列数范围1-3，电脑下棋位置由电脑产生随机数，也要保证范围，即行数范围1-3，列数范围1-3。
- 用户落棋点显示
*,电脑落棋点显示# - 如果棋盘的某一行、或某一列、或者任意一个对角线三个落棋点相同，即都是
*用户玩家获胜，或者都是#，那么电脑获胜 - 如果棋盘满了且不存在获胜的条件，那么平局
- 如果棋盘还有空格
' ',且不存在获胜条件，那么继续
菜单实现
void menu()
{
printf("*******************************\n");
printf("********* 1.play **********\n");
printf("********* 0.exit **********\n");
printf("*******************************\n");
}
选择1，表示进行游戏，选择0表示退出。
游戏棋盘初始化
void InitBoard(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++)
{
board[i][j] = ' ';
}
}
}
棋盘打印
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
//打印数据
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
//打印分割行
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("\n");
}
}
下棋过程
//下棋
char ret = 0;
while(1)
{
PlayerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
ret = IsWin(board, ROW, COL);//判断输赢
if (ret != 'C')
{
break;
}
ComputerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
ret = IsWin(board, ROW, COL);//判断输赢
if (ret != 'C')
{
break;
}
}
if (ret == '*')
{
printf("玩家赢\n");
}
else if (ret == '#')
{
printf("电脑赢\n");
}
else
{
printf("平局\n");
}
玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col)
{
printf("玩家走:>\n");
while (1)
{
int x = 0;
int y = 0;
printf("请输入坐标:>");
scanf("%d%d", &x, &y);
if (x >= 1 && x <= 3 && y >= 1 && y <= 3)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
{
printf("坐标已有落子，请重新输入\n");
}
}
else
{
printf("坐标非法，超出范围\n");
}
}
}
电脑下棋
void ComputerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑走:>\n");
while (1)
{
x = rand() % row;
y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
判断获胜情况
char IsWin(char board[ROW][COL], int row, int col)
{
//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];
}
}
//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];
}
}
//对角线
if (board[0][0] == board[1][1] && 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];
//判断平局
if (IsFull(board, row, col))
{
return 'Q';
}
//游戏继续
return 'C';
}
判断其盘满
//判断满，满了返回1，没满返回0
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;//不满
}
}
}
return 1;//棋盘满
}
