简易五子棋

第一次写博客，这次写的主要内容就是我打五子棋的过程分享，代码打的不太好，不够精简。

1.先从第一个开始，设置棋盘，我想的是让玩家设置棋盘大小，代码如下：

char** intalChessboard(int Row, int Col);
char** intalChessboard(int Row, int Col)
{
	char **chessboard = NULL;
	int i;
	int j;
	if(chessboard != NULL || Row != Col || Row < 0 || Col < 0 || Row > MaxRow || Col > MaxCol)
	{
		return;
	}
	chessboard = (char**)malloc(sizeof(char*)*Row);
	for(i = 0;i< Col; i++){
		chessboard[i] = (char*)malloc(sizeof(char)*Col);
	}
	for(i = 0; i < Row; i++)
	{
		for(j = 0; j < Col; j++)
		{
			chessboard[i][j] = '0';
		}
	}
	return chessboard;
}
void showChessboard(char**chessboard, int Row, int Col)
{
	int i;
	int j;
	for(i = 0; i < Row; i++)
	{
    	for(j = 0; j < Col; j++)
	 	{
	 	printf("%4c", chessboard[i][j]);
		}
		 printf("\n\n");
	}
}

其实没有必要给chessboard数组空间赋值字符零，纯属个人操作。在写这块代码时主要难度就是二重指针和二维数组的关系·，这块不做讲解，因为本人还有几个点没有彻底理解。

2.规则编写，五子棋的规则比较简单，就是五个相同的棋子连在一起则胜利。当玩家落棋子时，需要判断此处能否落子，和落子之后是否有五个棋子连在一起即可。代码如下：

boolean chessRule(char**chessboard, InUser chess)
{
	int i;
	int j;
	int a = chess.row - 1;
	int b = chess.col - 1;
	int index = 0;
	for(i = a, j = b; i >= 0 && j >= 0; i--, j--)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
			break;
		}
	}
		if(index == 5)
			{
				return TURE;
			}
	for(i = a + 1, j = b + 1; i <= MinRow && j <= MinCol; i++,j++)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
			break;
		}
	}
			if(index == 5)
			{
			return TURE;
            }
	index = 0;
	for(i = a , j = b ; i >= 0 && j <= MinCol; i--,j++)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
			break;
		}
	}
		if(index == 5)
			{
				return TURE;
			}		
	for(i = a + 1, j = b - 1; i <= MinRow && j >= 0; i++,j--)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
			break;
		}
	}
		if(index == 5)
			{
				return TURE;
			}
	index = 0;
		for(i = a, j = b; i >= 0; i--)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
    	}else{
			 	break;
			 }
	}
		if(index == 5)
			{
				return TURE;
			}
	for(i = a + 1, j = b; i < MinRow; i++)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
	    }else{
	    	break;
		}
	}
		if(index == 5)
			{
				return TURE;
			}
	index = 0;
		for(i = a, j = b;j >= 0; j--)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
			break;
		}
	}
	if(index == 5)
			{
				return TURE;
			}
	for(i = a, j = b + 1; j <= MinCol; j++)
	{
		if(chessboard[i][j] == chess.value)
		{
			index++;
		}else{
		break;
		}
	}
	if(index == 5)
		{
			return TURE;
		}
	return FALSE;
}

3.我一直再想怎样不清屏显示棋盘，突然想到了光标定位函数，输入相应的坐标，即可将坐标定位在此处，（可能还会有别的方法处理，对这类函数还是不太熟悉），这里有个问题要注意，屏幕坐标横行是x轴，竖列是y轴，而二维数组是横行是行，竖列是列，所以y是行下标，x是列下标。代码如下：

void gotoxy(int x, int y) //gotoxy 源代码
{
COORD pos;
pos.X= x - 1;
pos.Y= y - 1;
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos);
}
void chessLocation(InUser chess)
{
	gotoxy(4*chess.col,2*chess.row - 1);
	printf("%c", chess.value);
}

其中gotoxy()括号中的内容是根据你输入的棋盘大小计算出来的。

4.剩下的内容就是主函数中函数的调用和函数之间的调用顺序。代码如下:

#include <stdio.h>
#include <conio.h>
#include <windows.h> 
#define MinRow 5
#define MinCol 5
#define MaxRow 15
#define MaxCol 15

#define FALSE 0

其中有许多地方处理的不好，代码不够简便，开始写的时候主要是想写成工具，以后写五子棋的时候直接调用即可，但发现写完后写成工具难度有些大，感觉很难想。其实还有几个功能想实现，人机对战（这里我想的是把用户和用户之间下棋的胜局保存下来，可以设置难度等级）、用户之间的1对多模式、界面设计、通过键盘来控制棋子位置等等，奈何学艺不精。。望大佬指教。。
