C语言---五子棋

一.主函数：

int main()
{
	int input = 0;
	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，重新选择\n");
			break;
		}
	} while (input);

	return 0;
}

然后将菜单**menu:**写出来

void menu()
{
	printf("*******************************\n");
	printf("********    1. play      ******\n");
	printf("********    0. exit      ******\n");
	printf("*******************************\n");
}

二.头文件 ，可以更清晰看出
ROW 行数
COL 列数 ，利用#define的好处是可以变化

#include
#include
#include
#include
#define ROW 7
#define COL 7
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);

正文，最重要的部分！！！
1.先初始化棋盘：
初始化为空格
利用menset 代码更简单，便捷

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] = ' ';
		}
	}
	//memset(&board[0][0], ' ', row*col*sizeof(board[0][0]));
}

2.设置棋盘：

在这里插void DisplayBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 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");
	}

3.玩家与电脑下棋：
由于玩家的x从1开始，到row结束
但电脑是以下标，则x-1

void PlayerMove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家下棋:>\n");

	while (1)
	{
		printf("请输入要下棋的坐标:>");
		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("坐标被占用，重新输入\n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入\n");
		}
	}
}


//电脑随机下棋
void ComputerMove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("电脑下棋>:\n");

	while (1)
	{
		x = rand() % row;
		y = rand() % col;
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

4.判断输赢or平局：
*
行列同，对角线同：
判断输赢
玩家赢 - '’
电脑赢 - ‘#’
平局 - ‘Q’
继续 - ‘C’

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;
}

//判断输赢
//玩家赢 - '*'
//电脑赢 - '#'
//平局   - 'Q'
//继续   - 'C'

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];
	}
	//判断是否平局
	if (IsFull(board, row, col))//如果平局，则为真，为 1；
	{
		return 'Q';
	}
	//游戏继续
	return 'C';
}

三.然后写game：代码

void game()
{
	//存放数据需要一个3*3的二维数组
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//显示棋盘
	DisplayBoard(board, ROW, COL);
	char ret = 0;
	while (1)
	{
		//玩家下棋
		PlayerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}

		//电脑下棋
		ComputerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}//重复
	}
	if ('*' == ret)
	{
		printf("玩家赢\n");
	}
	else if ('#' == ret)
	{
		printf("电脑赢\n");
	}
	else if ('Q' == ret)
	{
		printf("平局\n");
	}
}

四.总结！！！
文件test.c：

#define _CRT_SECURE_NO_WARNINGS 1
#include "game.h"
void menu()
{
	printf("*******************************\n");
	printf("********    1. play      ******\n");
	printf("********    0. exit      ******\n");
	printf("*******************************\n");
}

void game()
{
	//存放数据需要一个3*3的二维数组
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//显示棋盘
	DisplayBoard(board, ROW, COL);
	char ret = 0;
	while (1)
	{
		//玩家下棋
		PlayerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}

		//电脑下棋
		ComputerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}//重复
	}
	if ('*' == ret)
	{
		printf("玩家赢\n");
	}
	else if ('#' == ret)
	{
		printf("电脑赢\n");
	}
	else if ('Q' == ret)
	{
		printf("平局\n");
	}
}

int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));
	do
	{
		menu();
		printf("请选择:>");

			game();
			break;
		case 0:

运行结果：

在用C语言设计五子棋游戏中，充分利用了C当中的数组和头文件的知识，通过设计五子棋的实践，更加深入的理解C，练习代码。有错误大家可以指出，共同进步。
