#c语言

本文详细介绍了使用C语言实现三子棋游戏的过程，包括创建项目、编写代码等步骤，并提供了完整的源代码。

一.创建项目

首先创建test.c game.c game.h三个文件.

test.c里放着三子棋的实现过程

game.c里放着实现游戏函数的定义

game.h里放着常量、game.c里函数的声明

二.开始编写

第一步：打印菜单

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


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("输入错误，请重新输入\n");
			break;
		}
	} while (input);
    	
	return 0;
}

第二步:

game()函数的实现:

首先要在game.h头文件中定义常量，方便后续修改

#define ROW 3
#define COL 3

然后再game()函数中先创建一个二维数组用来存放下棋的数据

    //存放下棋的数据
	char board[ROW][COL] = { 0 };

接着把棋盘初始化，创建一个初始化函数，在game.c里实现函数功能

//初始化棋盘
void InitBoard(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++)
		{
			board[i][j] = ' ';
		}
	}
}

打印函数

//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < ROW; i++)
	{
		//打印数据
		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 (i < col - 1)
				{
					printf("|");
				}
			}
			printf("\n");
		}	
	}
}

玩家下棋

void PlayerBoard(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	while (1)
	{
		printf("玩家下棋:>");
		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("该坐标被占用，请重新输入\n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入\n");
		}
	}
}

电脑下棋

void ComputerBoard(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;
		}
	}
}

判断输赢

static int if_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;
			}
		}
	}
	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][1] == board[i][2] && board[i][1] != ' ')
		{
			return board[i][1];
		}
	}
	//判断列
	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
		{
			return board[1][i];
		}
	}
	//判断对角线
	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];
	}
	//判断平局
	if (if_full(board, ROW, COL) == 1)
	{
		return 'Q';
	}

	return 'C';
}

接下来是完整的game.c game.h test.c

game.h

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

#define ROW 3
#define COL 3

//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 PlayerBoard(char board[ROW][COL], int row, int col);
//电脑下棋
void ComputerBoard(char board[ROW][COL], int row, int col);
//判断是否赢
char is_win(char board[ROW][COL], int row, int col);

game.c

#include "game.h"

		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
			{
				printf("|");
			}
		}
		printf("\n");
		if (i < row - 1)
		{
			for (j = 0; j < col; j++)

以上就是三子棋的全部实现代码，希望可以对你有些帮助。
