C语言实现简单扫雷

相信大家都玩过扫雷吧，以前机房上机，无聊的时候就开始玩扫雷和蜘蛛纸牌，有时候能玩好久好久。那今天，我们就来写一个简易的扫雷游戏吧！

和三子棋游戏一样，我们先把它需要的游戏功能列出来：
（1）void Menu();菜单
（2）void Game();游戏框架
（3）int GetRandIndex(int start, int end);随机生成雷的下标
（4）void SetMines(char mineboard[][COL], int row, int col);埋雷数组
（5）char ShowBoard(char mineboard[][COL], int row, int col)；扫雷数组
（6）int GetMines(char mineboard[][COL], int row, int col);判断用户选择的坐标周围有几个雷

接下来，我们依次实现这些子程序
1.菜单

void Menu()
{
	printf("#########################\n");
	printf("#####     1.Play    #####\n");
	printf("#####     2.Exit    #####\n");
	printf("#########################\n");
	printf("Please select:");
}

2.随机生成雷的下标，并且埋雷。
在生成随机数时，我们采用了 rand() % (end - start + 1) + start;
start和end是我们需要的随机数的范围。

int GetRandIndex(int start, int end)    //随机生成埋雷下标
{
	return rand() % (end - start + 1) + start;    
}
void SetMines(char mineboard[][COL], int row, int col)     //埋雷
{
	srand((unsigned long)time(NULL));   //随机数种子
	int count = 0;
	while (count < Mine_Num){
		int x = GetRandIndex(1, 10);
		int y = GetRandIndex(1, 10);
		if (mineboard[x][y] == '0'){
			mineboard[x][y] = '1';
			count++;
		}
	}
}

3.显示用户所选坐标周围有几个雷，我们在这里要注意，该函数的返回值为整型，但得到的mineboard为"1"的字符型，我们知道字符其实在ASCII码中也是一个阿拉伯数字。所以要得到阿拉伯数字就需要减去七个字符‘0’。

int GetMines(char mineboard[][COL], int row,int col)   //显示周围雷的数目
{
	return mineboard[row - 1][col - 1] + mineboard[row - 1][col] + mineboard[row - 1][col + 1] + mineboard[row][col - 1] + \
		mineboard[row][col + 1] + mineboard[row + 1][col - 1] + mineboard[row + 1][col] + mineboard[row + 1][col + 1] - 7 * '0';
}

4.展示棋盘，我们要明白在这个程序中，我们用了俩个数组，一个用来埋雷，一个用来给用户展示。而这个展示棋盘就是用来给用户扫雷并展示的。

char ShowBoard(char showboard[][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	printf("   ");
	for (i = 1; i <= 10; i++){
		printf("%d   ", i);
	}
	printf("\n");
	for (i = 0; i < col-1; i++){
		printf("----");
	}
	printf("\n");
	for (i = 1; i <= row - 2; i++)
	{
		printf("%-2d|", i);
		for (j = 1; j <= col - 2; j++)
		{
			printf(" %c |", showboard[i][j]);
		}
		printf("\n");
		int k = 1;
		for (k = 1; k <= col - 1; k++)
		{
			printf("----");
		}
		printf("\n");
	}
}

5.整个游戏的框架。

oid Game()
{
	char mineboard[ROW][COL];
	char showboard[ROW][COL];
	memset(mineboard, '0', sizeof(mineboard));  //将埋雷数组全都清0
	memset(showboard, '*', sizeof(showboard));  //将扫雷数组全都置*
	SetMines(mineboard, ROW, COL);  //随机设置雷
	int count = TOTAL;
	int x = 0;
	int y = 0;
	while (1){
		ShowBoard(showboard, ROW, COL);
		printf("Please select:");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= ROW - 2 && y >= 1 && y <= COL - 2){
			if (mineboard[x][y] == '0'){
				char num = GetMines(mineboard, x, y);   
				showboard[x][y] = num;
				//Showboard(mineboard, ROW, COL);
				count--;
				if (count <= 20){
					printf("恭喜你，完美避开所有的雷区！\n");
					break;
				}
			}
			else{
				printf("实在是太遗憾了，你被炸死了！\n");
				break;			
			}
		}
		else{
			printf("输入有误，请重新选择！\n");
		}
	}
}

未了避免代码冗余，且可读性强，我们这里使用头文件进行函数声明等。

函数声明 mine.h

#ifndef _MINE_H_
#define _MINE_H_

#include
#include
#include
#pragma warning(disable:4996)

#define ROW 12
#define COL 12
#define TOTAL 10*10
#define Mine_Num 20

void Menu();
void Game();
int GetRandIndex(int start, int end);
void SetMines(char mineboard[][COL], int row, int col);
char ShowBoard(char mineboard[][COL], int row, int col);
int GetMines(char mineboard[][COL], int row, int col);


#endif

函数实现 mine.c

#include "mine.h"

int GetRandIndex(int start, int end)    //随机生成埋雷下标
{
	return rand() % (end - start + 1) + start;
}
void SetMines(char mineboard[][COL], int row, int col)
{
	srand((unsigned long)time(NULL));
	int count = 0;
	while (count < Mine_Num){
		int x = GetRandIndex(1, 10);
		int y = GetRandIndex(1, 10);
		if (mineboard[x][y] == '0'){
			mineboard[x][y] = '1';
			count++;
		}
	}
}
int GetMines(char mineboard[][COL], int row,int col)   //显示周围雷的数目
{
	return mineboard[row - 1][col - 1] + mineboard[row - 1][col] + mineboard[row - 1][col + 1] + mineboard[row][col - 1] + \
		mineboard[row][col + 1] + mineboard[row + 1][col - 1] + mineboard[row + 1][col] + mineboard[row + 1][col + 1] - 7 * '0';
}
char ShowBoard(char showboard[][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	printf("   ");
	for (i = 1; i <= 10; i++){
		printf("%d   ", i);
	}
	printf("\n");
	for (i = 0; i < col-1; i++){
		printf("----");
	}
	printf("\n");
	for (i = 1; i <= row - 2; i++)
	{
		printf("%-2d|", i);
		for (j = 1; j <= col - 2; j++)
		{
			printf(" %c |", showboard[i][j]);
		}
		printf("\n");
		int k = 1;
		for (k = 1; k <= col - 1; k++)
		{
			printf("----");
		}
		printf("\n");
	}
}

void Game()
{
	char mineboard[ROW][COL];
	char showboard[ROW][COL];
	memset(mineboard, '0', sizeof(mineboard));  //将埋雷数组全都清0
	memset(showboard, '*', sizeof(showboard));  //将扫雷数组全都置*
	SetMines(mineboard, ROW, COL);
	int count = TOTAL;
	int x = 0;
	int y = 0;
	while (1){
		ShowBoard(showboard, ROW, COL);
		printf("Please select:");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= ROW - 2 && y >= 1 && y <= COL - 2){
			if (mineboard[x][y] == '0'){
				char num = GetMines(mineboard, x, y);
				showboard[x][y] = num;
				//Showboard(mineboard, ROW, COL);
				count--;
				if (count <= 20){
					printf("恭喜你，完美避开所有的雷区！\n");
					break;
				}
			}
			else{
				printf("实在是太遗憾了，你被炸死了！\n");
				break;			
			}
		}
		else{
			printf("输入有误，请重新选择！\n");
		}
	}
}

主函数main.c

#include "mine.h"

void Menu()
{
	printf("#########################\n");
	printf("#####     1.Play    #####\n");
	printf("#####     2.Exit    #####\n");
	printf("#########################\n");
	printf("Please select:");
}

int main()
{
	int select = 0;
	int quit = 0;
	while (quit!=1){
		Menu();
		scanf("%d", &select);
		switch (select){
		case 1:
			Game();
			break;
		case 2:
			printf("Bye-bye!\n");
			quit = 1;
			break;
		default:
			printf("Select error!Please select again!\n");
			break;
		}
	}
}

运行结果：
