三子棋
三子棋的基本流程
玩家来到来到游戏界面选择是否玩游戏：“1”为玩游戏；“0”为退出游戏，如果玩家选择其他数字那么系统提示他选择错误并让玩家重新做出选择，玩家选择“1”后玩家开始下棋“@”电脑下棋"#“其中电脑和玩家每下一步其就做出判断：是否有3个”@“能否连接成一条直线如果有则玩家获胜，是否有3个”#"能否连接成一条直线如果有则玩家获胜，如果棋盘已满没有获得胜利则为平均。
三子棋的函数界面
#pragma once
#include<time.h>
#include<stdlib.h>
#include<stdio.h>
#define ROW 3
#define COL 3
//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);
//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);
//电脑下棋
void ComputerMove(char board[ROW][COL], int row, int col);
//判断游戏的输赢
char IsWin(char board[ROW][COL], int row, int col);
三子棋的游戏界面
“0”为退出游戏 “1”玩游戏 其他数字则显示异常
void menu()
{
printf("***********************************\n");
printf("******** 1.play ********\n");
printf("******** 0.exit ********\n");
printf("***********************************\n");
}
三子棋的初始化
可定义字符二维数组
board[ROW][COL]为空格
void InitBoard(char board[ROW][COL], int row, int col)
{
for (int i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
board[i][j] = ' ';
}
}
}
打印三子棋棋盘
void DisplayBoard(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++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("\n");
}
}
玩家下棋
玩家下棋输入三子棋坐标如果坐标被占用则需要重新选择坐标
void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
while (1)
{
printf("请选择第三子棋坐标>");
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("该输入的坐标已经被占用\n");
}
}
else
{
printf("输入坐标错误\n");
}
}
}
电脑下棋
电脑设置两个随机值，再将进行条件判断
void ComputerMove(char board[ROW][COL], int row, int col)
{
printf("电脑走>\n");
while (1)
{
int x = rand() % row;
int y = rand() % col;
if (board[x][y] == ' ')
{
board[x ][y ] = '#';
break;
}
}
}
三子棋的判断胜负
是否有3个"@“能否连接成一条直线如果有则玩家获胜，是否有3个”#"能否连接成一条直线如果有则玩家获胜，如果棋盘已满没有获得胜利则为平均。
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;
}
}
}
return 1;
}
char IsWin(char board[ROW][COL], int row, int col)
{
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];
}
}
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];
}
}
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];
if (IsFull(board, row, col))
{
return 'Q';
}
return 'C';
}
