接下来手把手教你用C语言实现三子棋

第一步

建立一个项目 ——》在项目中建立三个文件：text.c game.c game.h

第二步

分析三子棋实现步骤 ：

1.交互页面：输入1 —— 玩       输入0 —— 退出游戏

 2.建立棋盘

3. 下棋

 

5.判断结果

 第三步

代码实现：

test.c

#define  _CRT_SECURE_NO_WARNINGS 1
#include"game.h"

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

void Gobang()
{
	srand((unsigned)time(NULL));
	char tmp = 'C';
	char board[Line][Row] = { 0 };//棋盘
	//1.初始化棋盘
	initial(board, Line, Row);
	//2.打印棋盘
	print(board, Line, Row);
	while (1)
	{
		//3.下棋（玩家先下，电脑再下）
		//玩家下
		player(board, Line, Row);
		tmp = judge(board, Line, Row);
		if (tmp != 'C')
			break;
		print(board, Line, Row);//打印棋盘
		//电脑下
		computer(board, Line, Row);
		tmp = judge(board, Line, Row);
		if (tmp != 'C')
			break;
		print(board, Line, Row);//打印棋盘
		//4.判断输赢
	}
	if (tmp == '*')
		printf("玩家赢\n");
	else if (tmp == '#')
		printf("电脑赢\n");
	else
		printf("平局\n");
	print(board, Line, Row);//打印棋盘

}

int main()
{
	
	int input = 0;
	do
	{
		menu();
		printf("请输入你的选择 >> ");
		scanf("%d", &input);
		switch (input)
		{
		case 1:Gobang(); break;//开始游戏
		case 0:printf("退出游戏\n"); break;
		default:printf("请重新输入\n"); break;
		}

	} while (input!=0);
	
	system("pause");
