C语言实现简单的三子棋小游戏

函数实现的基本功能：

1.初始化棋盘：用空字符初始化

2.打印棋盘：控制打印九宫格来表示棋盘

3.玩家下棋：用P表示玩家的棋子

4.电脑随机下棋：随机生成坐标，用0表示玩家的棋子

5.判断输赢：玩家赢，电脑赢，平局，继续游戏四种情况

多文件实现：

测试部分test.c代码

#include<windows.h>
#include"game.h"
menu()
{
	printf("###############################\n");
	printf("#######欢迎来到三子棋游戏######\n");
	printf("####### 1.play    0.exit ######\n");
	printf("###############################\n");
}
void game()
{
	char board[ROW][COL] = { 0 };
	char win = 0;
	InitBoard(board, ROW, COL);//初始化空格棋盘
	//打印棋盘
	PrintBoard(board, ROW, COL);
	do
	{
		PlayerMove(board, ROW, COL);//玩家走
	    PrintBoard(board, ROW, COL);
		win = CheckWin(board, ROW, COL);//检测输赢;玩家赢P 电脑赢0  继续游戏 平局E 
		if (win != ' ')
			break;
		ComputerMove(board, ROW, COL);//电脑走
		PrintBoard(board, ROW, COL);
		win = CheckWin(board, ROW, COL);
		if (win != ' ')
	       {

                       break;
		PrintBoard(board, ROW, COL);

               }
	}
	while (1);
	if (win == 'P')
		printf("恭喜你你赢了\n");
	else if (win == '0')

		printf("不好意思电脑赢了\n");
	else if (win == 'E')
		printf("平局\n");

}

void test()
{
	int input = 0;
	srand((unsigned)time(NULL));
	do{
      	menu();//打印菜单
		printf("请选择;>");
		scanf_s("%d",&input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误\n");
			break;
		}
	} while (input);
}


int main()
{
	test();
	
	system("pause");
	return 0;
}

游戏头文件game.h代码

#ifndef  _GAME_H_
#define  _GAME_H_


#include<stdio.h>
#include<stdlib.h>
#include<time.h>


#define ROW 3
#define COL 3


void InitBoard(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 CheckWin(char board[ROW][COL], int row, int col);

游戏实现部分game.c

#include<stdio.h>
#include "game.h"

void InitBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{

		{
			board[i][j] = ' ';
		}
	}


}
void PrintBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		printf(" %c | %c | %c \n",board[i][0],board[i][1],board[i][2]);
		if (i<row-1)
			printf("---|---|---\n");
	}

}
void PlayerMove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	while (1)
	{
		printf("玩家下棋>:");
		scanf_s("%d%d", &x, &y);
		if (x >= 1 && x <= ROW && y>= 1 && y<= COL)//判断坐标合法性
		{
			//判断坐标是否被走过
			if (board[x-1][y-1] == ' ')
			{
				board[x-1][y-1] = 'P';
				break;
			}
			else
				printf("该步已经被走过\n");
		}
		else
			printf("坐标输入有误请重新输入\n");

	}

}
int  is_full(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;//不满返回0
		}
	}return 1;//满了返回1
}
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;//随机值0-2
		y = rand() % COL;//随机值0-2
		if (board[x][y] == ' ')
		{
			board[x][y] = '0';
			break;
		}

	}
}
char CheckWin(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][0] == board[i][2] && board[i][0] != ' ')
		{
			return board[i][0];
		}
	}//处理行相等
	for (i = 0; i < row; i++)
	{
		if (board[0][i] == board[1][i] && board[0][i] == board[2][i] && board[0][i] != ' ')
		{
			return board[0][i];
		}
	}//处理列相等

		if (board[0][0] == board[1][1] && board[0][0] == board[2][2] && board[0][0] != ' ')
		{
			return board[1][1];
		}
		if (board[0][2] == board[1][1] && board[0][2] == board[2][0] && board[0][2] != ' ')
		{
			return board[1][1];
		}//处理对角线相等

		if (is_full(board, row, col) == 1)
		{
			return'E';

		}return' ';

}

以上只是简单的实现部分，还望各位大佬多多指点！
