C语言-9（三子棋）

1.创建源文件test.c放入以下代码

#include<stdio.h>
#include"game.h"
void menu()
{
	printf("*******************************\n");
	printf("***  1 . play     0 . exit  ***\n");
	printf("*******************************\n");

}
void game()
{	
	char ret;
	char board[ROW][COL] = {0};//全部空格
	InitBoard(board,ROW,COL);
	DisplayBoard(board,ROW,COL);//打印棋盘
	while(1)
	{
		PlayerMove(board,ROW,COL);//玩家下棋
		DisplayBoard(board,ROW,COL);
		ret=IsWin(board,ROW,COL);
		if(ret!='C')
		{
			break;
		}
		ComputerMove(board,ROW,COL);
		DisplayBoard(board,ROW,COL);
		IsWin(board,ROW,COL);
		if(ret!='C')
		{
			break;
		}
	
	}
	if(ret=='*')
	{
		printf("玩家赢\n");
	}
	else if(ret=='#')
	{
		printf("电脑赢\n");
	}
	else
	{
		printf("平局\n");
	}

}
void test()
{
	int input;
	srand((unsigned int)time(NULL));
	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，请重新选择\n"); 
			break;
		}
	}while(input);

}

int main()
{
	test();
	return 0;

}

2.创建源文件game.c放入以下代码

#include"game.h"
#include<stdio.h>
void InitBoard(char board[ROW][COL],int row,int col)
{
	int i,j;
	for(i=0;i<row;i++)
	{
		for(j=0;j<col;j++)
		{
			board[i][j] = ' ';
		}
	}


}
void DisplayBoard(char board[ROW][COL],int row,int col)
{
	int i,j;
	for(i=0;i<row;i++)
	{	//打印一行数据
		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");

	}


}
void PlayerMove(char board[ROW][COL],int row,int col)
{
	int x,y;
	printf("玩家走:\n");
	while(1)
	{
		printf("请输入下的坐标:");
		scanf("%d%d",&x,&y);
		//判断xy合法性
	    if(x>=1 && x<=row && y>=1 &&y<=col)
		{
			if(board[x-1][y-1] == ' ')
			{
				board[x-1][y-1] = '*';
				break;
			}
			else
			{
				printf("改点坐标被占用\n");
			}
		}
		else
		{
			printf("非法坐标，请重新输入！\n");
		}
	}
}
void ComputerMove(char board[ROW][COL],int row,int col)
{
	int x,y;
	printf("电脑走:\n");
	while(1)
	{
		x=rand()%row;
		y=rand()%col;
		if(board[x][y]==' ')
		{
			board[x][y]='#';
			break;
		}
	}
}
int IsFull(char board[ROW][COL],int row,int col)
{
	int i,j;
	for(i=0;i<row;i++)
	{
		for(j=0;j<col;j++)
		{
			if(board[i][j]==' ')
			{
				return 0;//没满
			}
		}
	
	}
	return 1;//满了
}
char IsWin(char board[ROW][COL],int row,int col)
{
	int i;
	for(i=0;i<row;i++)
		if(board[i][0]==board[i][1]&&board[i][1]==board[i][2]&&board[i][1]!=' ')
		{
		return board[i][1];
		}
	for(i=0;i<row;i++)
		if(board[0][i]==board[1][i]&&board[1][i]==board[2][i]&&board[1][i]!=' ')
		{
		return board[i][1];
		}
		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(1==IsFull(board,ROW,COL))
		{
			return 'Q';
		}
		return'C';
}

3.创建头文件game.h放入以下代码

#define ROW 3
#define COL 3
#include<stdlib.h>
#include<time.h>
void InitBoard(char board[ROW][COL],int row,int col);
void DisplayBoard(char board[ROW][COL],int row,int col);
void PlayerMove(char board[ROW][COL],int row,int col);
void ComputerMove(char board[ROW][COL],int row,int col);
char IsWin(char board[ROW][COL],int row,int col);

4.运行结果如下：

5.选择1进入游戏

6.然后输入坐标
1）玩家win

2）电脑win

3）平局

最后程序可以完美运行了！！！！
