C语言实现三子棋

1.整体思路

用C语言实现三子棋，首先你要明确实现思路，实现过程。

a.目录实现-->b.下棋数据的存储-->c.初始化棋盘-->d.打印棋盘-->e.玩家下棋-->f.电脑下棋-->g.判断输赢-->h.宏观调整逻辑实现

2.分模块实现

    a.目录实现

#define _CRT_SECURE_NO_WARNINGS  1
#include
void menu()
{
	printf("*******三子棋人机对战*******\n");
	printf("****************************\n");
	printf("*******    1.play    *******\n");
	printf("*******    0.exit    *******\n");
	printf("****************************\n");
}
void test()
{
	int input = 0;
	menu();
	do
	{
		printf("请选择:>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("输入错误，请重新输入\n");
			break;
		}
	}while(input);
}
int main()
{
	test();
	return 0;
}

    b.游戏整体实现

​
#include "game.h"
void game()
{
	char ret = 0;
	//存储下棋的数据（3x3的二维数组）
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//打印棋盘
	DisplayBoard(board, ROW, COL);
	while (1)
	{
		//玩家下棋
		player_move(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		//电脑下棋
		computer_move(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
    }
	if (ret == '*')
	{
		printf("玩家赢\n");
	}
	if (ret == '#')
	{
		printf("电脑赢\n");
	}
	if (ret == 'Q')
	{
		printf("平局\n");
	}
}

​

   c.宏定义 功能函数的声明

#pragma once
#define ROW 3
#define COL 3

#include
#include
#include

//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 player_move(char board[ROW][COL], int row, int col);

//电脑下棋
void computer_move(char board[ROW][COL], int row, int col);

//判断输赢
char is_win(char board[ROW][COL], int row, int col);

  d.功能函数

#define _CRT_SECURE_NO_WARNINGS  1
#include"game.h"
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] = ' ';
		}
	}
}
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");
		for (j = 0; j < col; j++)
		{
			if (i < row - 1)
			{
				printf("---");
				if (j < col - 1)
				{
					printf("|");
				}
			}
		}
		printf("\n");
	}
}
void player_move(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家下棋\n");
	while (1)
	{
		printf("请输入坐标;>");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col && board[x-1][y-1] == ' ')
		{
			board[x - 1][y - 1] = '*';
			break;
		}
		else
		{
			printf("输入错误，请重新输入\n");
		}
	}
}
void computer_move(char board[ROW][COL], int row, int col)
{
	while (1)
	{
		int x = rand() % row;
		int y = rand() % col;
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}
int is_full(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++)
		{
			if (board[i][j] == ' ')
			{
				return 0;
			}
		}
	}
	return 1;
}
char is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	//判断行
	for (i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][0] == board[i][2] && board[i][1] != ' ')
		{
			return board[i][0];
		}
	}
	//判断列
	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[0][i] == board[2][i] && board[1][i] != ' ')
		{
			return board[0][i];
		}
	}
	//对角线
	if (board[1][1] == board[2][2] && board[0][0] == board[2][2] && board[0][0] != ' ')
	{
		return board[0][0];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (is_full(board, ROW, COL) == 1)
	{
		return 'Q';
	}
	return 'C';
}
