C语言实现N子棋

学习了数组之后，我尝试写了一段N子棋代码，采用了面向对象的编程思想，将绘画棋盘，落子，规则分别作为对象，编程以实现功能，作为初学者，编程过程中可能有一些不正确的地方或者又可以改进的地方，请大家批评指正。

主函数：

#define _CRT_SECURE_NO_WARNINGS
#include
#include"game.h"

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

void game()
{
	char board[ROW][COL] = {0};		//创建棋盘
	InitBoard(board, ROW, COL);		//初始化棋盘
	DisplayBoard(board,ROW,COL);	//打印棋盘
	//   |   |   
	//---|---|---
	//   |   |   
	//---|---|---
	//   |   |   
	while (1)
	{
		int a = 0;
		PlayerMove(board,ROW,COL);
		DisplayBoard(board, ROW, COL);
		a=Judge(board,ROW,COL,WIN);
		switch (a)
		{
		case 1:
			printf("你赢了！\n");
			break;
		case 2:
			printf("你输了！\n");
			break;
		case 3:
			printf("平局！\n");
			break;
		case 4:
			break;
		}
		if (a != 4)
			break;
		ComputerMove(board,ROW,COL);
		DisplayBoard(board, ROW, COL);
		a = Judge(board, ROW, COL,WIN);
		switch (a)
		{
		case 1:
			printf("你赢了！\n");
			break;
		case 2:
			printf("你输了！\n");
			break;
		case 3:
			printf("平局！\n");
			break;
		case 4:
			break;
		}
		if (a != 4)
			break;
	}
}

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

int main()
{
	test();
	return 0;
}

头文件：

#define _CRT_SECURE_NO_WARNINGS
#define ROW 3
#define COL 3
#define WIN 3

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);
int Judge(char board[ROW][COL], int row, int col,int win);

在头文件中可以更改棋盘的大小和N子棋中N的数值

棋盘行数定义在ROW中，列数定义在COL中

声明的函数InitBoard可以初始化棋盘，将数组每一个元素都赋值为空格（‘ ’）

函数DisplayBoard可以将棋盘实时绘画出来

函数PlayerMove和ComputerMove分别为玩家落子和电脑落子操作函数

函数Judge为裁判函数，每一次落子后，检验游戏是否结束
