关于五子棋

 （关于五子棋）         第一次用 c编写小游戏，可能还有很多不足，但是心里满满的成就感。

1.游戏的测试

<pre class="objc" name="code">void menu()
{
	printf("   1.play    ");
	printf("   0.exit    ");
}

void game()
{
	char ret;
	char board[ROWS][COLS];
	init_board(board,ROWS,COLS);
	display_board(board,ROWS,COLS);
	while(1)
	{
	   man_play_chess(board,ROWS,COLS);
	   if((ret = judge_win(board,ROWS,COLS))!=' ')
	       break;
	   display_board(board,ROWS,COLS);
	   pc_play_chess(board,ROWS,COLS);
	   if((ret = judge_win(board,ROWS,COLS))!=' ')
	       break;
	   display_board(board,ROWS,COLS);
	}
	   display_board(board,ROWS,COLS);
	   if(ret == 'x')
		   printf("恭喜,你赢了");
	    else if(ret == 'c')
		   printf("电脑赢了哈哈");
	   else if(ret == 'q')
		   printf("平局呵呵");
}

int main()
{
	int input = 0;	
	srand((unsigned)time(NULL));
	do
	{
		menu();
		printf("请选择：");
		scanf("%d",&input);
		switch(input)
		{
		case 0:
			break;
		case 1:
			game();
			break;
		default:
			printf("请重新选择：");
		}
	}while(input);
}

<span style="font-size:18px;"> 2.初始化并显示棋盘（棋盘做的不太好看<img alt="害羞" )</span>

void init_board(char board[ROWS][COLS],int row,int col)
{
	memset(board,' ',col*row*sizeof(char));
}

void display_board(char board[ROWS][COLS],int row,int col)
{
	int i = 0;
	for(i=0; i<row; i++)
	{
		printf(" %c | %c | %c | %c | %c \n",board[i][0],board[i][1],board[i][2],board[i][3],board[i][4]);
		if(i != row)
			printf("___|___|___|___|___|\n");
	}

}

<span style="font-size:18px;"> 3.玩家走棋</span>

void  man_play_chess(char board[ROWS][COLS],int row,int col)
{
	  int i = 0;
	  int j = 0;
	  while(1)
	{
	  printf("请输入落子的位置：");
	  scanf("%d %d",&i,&j);
	  if(i>=1&&j>=1&&i<=row&&j<=col&&board[i-1][j-1]==' ')
	  {
		  board[i-1][j-1] = 'x';
		  break;
	  }
	  else
		  printf("下标有误");
	}
}

4.电脑走棋

void pc_play_chess(char board[ROWS][COLS],int row,int col)
{
	while(1)
	{
	    int a = rand()%row; 
	    int b = rand()%col;
		if(board[a][b] == ' ')
		{
		  board[a][b] = 'c';
		  break;
		}
	}
}

5.判断棋盘是否已满

int is_full(char board[ROWS][COLS],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;

}

<span style="font-size:18px;">6.判断输赢（这个判断函数写的过于繁琐，希望以后有机会有能力再优化一下</span>

int judge_win(char board[ROWS][COLS],int row,int col)
{
	int i = 0;
	int j = 0;
	int count = 0;
	int count1 = 0;
	int count2 = 0;
	int count3 = 0;
	int count4 = 0;
	for(i=0; i<row; i++)
	{
		count = 0;
		for(j=0; j<col; j++)
		{
			if(board[i][j] == 'x')
				count++;
		}
		if(count == row)
           return 'x';
	}
	for(i=0; i<row; i++)
	{
		count = 0;
		for(j=0; j<col; j++)
		{
			if(board[i][j] == 'c')
				count++;
		}
		if(count == row)
			return 'c';
	}
	for(j=0; j<col; j++)
	{
		count = 0;
		for(i=0; i<row; i++)
		{
			if(board[i][j] == 'x')
				count++;
		}
		if(count == col)
			return 'x';
	}
	for(j=0; j<col; j++)
	{
		count = 0;
		for(i=0; i<row; i++)
	    {
			if(board[i][j] == 'c')
				count++;
		}
		if(count == col)
			return 'c';
	}
	for(i=0; i<row; i++)
	{
		if(board[i][i] == 'x')
			count1++;
		if(count1 == row)
			return 'x';
	}
	for(i=0; i<row; i++)
	{
		if(board[i][i] == 'c')
			count2++;
		if(count2 == row)
			return 'c';
	}
	for(i=0; i<row; i++)
	{
		if(board[i][row-1-i] == 'c')
				count3++;
		if(count3 == row)
			return 'c';
	}
	for(i=0; i<row; i++)
	{
		if(board[i][row-1-i] == 'x')
			count4++;
		if(count4 == row)
			return 'x';
	}
	if(is_full(board, ROWS,COLS) == 1)
		return 'q';

	return ' ';
