小游戏之扫雷

扫雷游戏实现

1.头文件game.h

#ifndef _GAME_H_
#define _GAME_H_

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

#pragma warning(disable:4996)

#define ROWS 10
#define COLS 10

void game();
void setMines(char board[ROWS + 2][COLS + 2], int rows, int cols, int bomb);
int getMines(char board[ROWS + 2][COLS + 2], int x, int y);
void display(char board[ROWS + 2][COLS + 2], int rows, int cols);

#endif

2.源文件game.c

#include"game.h"

   1)getRandomNum --> 获得指定区间的随机数

static int getRandomNum(int start, int end)
{
	return (rand() % (end - start + 1) + start);
}

   2)setMines --> 埋雷

void setMines(char board[ROWS + 2][COLS + 2], int rows, int cols, int bomb)
{
	int x = 0;
	int y = 0;
	srand((unsigned long)time(NULL));
	for (int i = 0; i < bomb; i++)
	{
		x = getRandomNum(1, rows);
		y = getRandomNum(1, cols);
		if ('0' == board[x][y])
		{
			board[x][y] = '1';
		}
		else
		{
			i -= 1;
		}
	}
}

   3)display --> 显示界面

void display(char board[ROWS + 2][COLS + 2], int rows, int cols)
{
	int i = 0;
	int j = 0;
	printf("   ");
	for (i = 0; i < cols; i++)
	{
		printf("%2d ", i + 1);
	}
	printf("\n");
	printf("   ");
	for (i = 0; i < cols; i++)
	{
		printf("---");
	}
	printf("\n");
	for (i = 1; i <= rows; i++)
	{
		printf("%2d|", i);
		for (j = 1; j <= cols; j++)
		{
			printf("%2c|", board[i][j]);
		}
		printf("\n");
	}
}

   4)getMines --> 计算四周的雷数

int getMines(char board[ROWS + 2][COLS + 2], int x, int y)
{
	return (board[x - 1][y - 1] + board[x - 1][y] + board[x - 1][y + 1] \
		+ board[x][y - 1] + board[x][y + 1] \
		+ board[x + 1][y - 1] + board[x + 1][y] + board[x + 1][y + 1] - 8 * '0');
}

   5)eRound --> 向四周扩展

int eRound(char mine[ROWS + 2][COLS + 2], char show[ROWS + 2][COLS + 2], int rows, int cols, int x, int y)
{
	int number = eSelf(mine, show, rows, cols, x, y);
	if ('0' == show[x][y])
	{
		int a = 0;
	begin:
		if ((x - 1) >= 1 && (y - 1) >= 1)
		{
			a = eSelf(mine, show, rows, cols, --x, --y);
			number += a;
			if ((show[x][y] == '0') && (a != 0))
			{
				goto begin;
			}
		}
		if ((x - 1) >= 1 && (y + 1) <= cols)
		{
			a = eSelf(mine, show, rows, cols, --x, ++y);
			number += a;
			if (show[x][y] == '0' && (a != 0))
			{
				goto begin;
			}
		}
		if ((x + 1) <= cols && (y - 1) >= 1)
		{
			a = eSelf(mine, show, rows, cols, ++x, --y);
			number += a;
			if (show[x][y] == '0' && (a != 0))
			{
				goto begin;
			}
		}
		if ((x + 1) <= cols && (y + 1) <= cols)
		{
			a = eSelf(mine, show, rows, cols, ++x, ++y);
			number += a;
			if (show[x][y] == '0' && (a != 0))
			{
				goto begin;
			}
		}
	}
	return number;
}

   6)eself --> 展开自己

int eSelf(char mine[ROWS + 2][COLS + 2], char show[ROWS + 2][COLS + 2], int rows, int cols, int x, int y)
{
	int num = 0;
	if ((x >= 1 && x <= rows) && (y >= 1 && y <= cols))
	{
		if (('*' == show[x][y]) && mine[x][y] != 1)
		{
			int count = getMines(mine, x, y);
			show[x][y] = count + '0';
			num++;
		}
		else if (mine[x][y] != 1)
		{
			int count = getMines(mine, x, y);
			show[x][y] = count + '0';
		}
		else
		{
			return 0;
		}
		if ('0' == show[x][y])
		{
			if (('*' == show[x - 1][y - 1]) && ((x - 1) >= 1 && (x - 1) <= rows) && ((y - 1) >= 1 && (y - 1) <= cols))
			{
				show[x - 1][y - 1] = '/';
				num++;
			}
			if (('*' == show[x - 1][y]) && ((x - 1) >= 1 && (x - 1) <= rows) && (y >= 1 && y <= cols))
			{
				show[x - 1][y] = '/';
				num++;
			}
			if (('*' == show[x - 1][y + 1]) && ((x - 1) >= 1 && (x - 1) <= rows) && ((y + 1) >= 1 && (y + 1) <= cols))
			{
				show[x - 1][y + 1] = '/';
				num++;
			}
			if (('*' == show[x][y - 1]) && (x >= 1 && x <= rows) && ((y - 1) >= 1 && (y - 1) <= cols))
			{
				show[x][y - 1] = '/';
				num++;

			{
				show[x + 1][y - 1] = '/';
				num++;
			}
			if (('*' == show[x + 1][y]) && ((x + 1) >= 1 && (x + 1) <= rows) && (y >= 1 && y <= cols))

			{
				show[x + 1][y + 1] = '/';
				num++;
			}
		}
	}
	return num;
}

   7)game --> 扫雷函数

void game()
{
	char choose;//选择难度
	int bomb = 0;//炸弹数目
	int x = 0;//横坐标
	int y = 0;//纵坐标
	int win = 0;//排弹成功
	char mine[ROWS + 2][COLS + 2];
	char show[ROWS + 2][COLS + 2];
	memset(mine, '0', (ROWS + 2)*(COLS + 2));

		goto START;
	}
	setMines(mine, ROWS, COLS, bomb);
	display(show, ROWS, COLS);

	//display(mine, ROWS, COLS);
	
	while ((ROWS*COLS - bomb) > win)
	{
		printf("please choose locate:");
		scanf("%d %d", &x, &y);
		if ((x >= 1 && x <= ROWS) && (y >= 1 && y <= COLS))
		{

	{
		printf("Congratulation!Victory!!!\n");
	}
	else
	{
		printf("bug!\n");
	}
}

3.源文件main.c

#include"game.h"

   1)mane --> 菜单界面

void manu()
{
	printf("#########################################\n");
	printf("######      1.START    0.EXIT      ######\n");
	printf("######    E(易)   M(中)   D(难)    ######\n");
	printf("#########################################\n");
}

   2)main --> 主函数

int main()
{
	int input = 0;
	do
	{
		manu();
		printf("Please input(1/0):");
		scanf("%d", &input);

		switch (input)
