相信大家都玩過(guò)掃雷游戲，在學(xué)習(xí)了二維數(shù)組之后，我也用c語(yǔ)言寫(xiě)了一個(gè)簡(jiǎn)單的掃雷游戲規(guī)則如下：

1.通過(guò)對(duì)宏Row和宏List來(lái)設(shè)置游戲的棋盤(pán)大?。ㄈ绻胪?0x10的掃雷則需設(shè)置Row和List為12）；

2.通過(guò)對(duì) 宏BoomNumber 來(lái)設(shè)置局中雷的個(gè)數(shù)（雷的個(gè)數(shù)需要<=（Row-2）*（List-2））；

3.對(duì) 用戶輸入要掃描的坐標(biāo)，如果有雷則雷爆炸游戲結(jié)束，如果沒(méi)有雷則統(tǒng)計(jì)出該坐標(biāo)周?chē)睦椎膫€(gè)數(shù)，一直循環(huán)此操作，直到棋盤(pán)中未掃描的地方全是雷為止則掃雷成功。

#pragma warning (disable:4996)#pragma once#include#include#include#define Row 12#define List 12#define BoomNumber 20#define Boom "1"http://1為有雷#define nice "0"extern void Game();extern void SetMine(char MineBoard, int row, int list);extern void Select(char MineBoard, int row, int list);extern void Menu();extern void CountBoom(char MineBoard[][List], int row, int list, int x, int y);

這便是掃雷游戲的頭文件，里面聲明的函數(shù)和定義的宏會(huì)在下文中一一解釋

問(wèn)題的關(guān)鍵在于：

1.如何給棋盤(pán)隨機(jī)埋入BoomNumber個(gè)雷

2.用戶選擇掃雷的坐標(biāo)后系統(tǒng)發(fā)現(xiàn)此處沒(méi)有雷如何統(tǒng)計(jì)出周?chē)椎膫€(gè)數(shù)并且讓用戶看到

考慮到只有在雷爆炸后用戶才需要知道系統(tǒng)埋雷的位置，其余時(shí)間不需要讓用戶看見(jiàn)埋雷的位置，為了方便我們需要設(shè)置兩個(gè)棋盤(pán)，一個(gè)用來(lái)埋雷另外一個(gè)則展示給用戶，棋盤(pán)有橫有縱，所以我們考慮用 兩個(gè)類(lèi)型相同的二維數(shù)組埋雷的棋盤(pán)為MineBoard[Row][List]展示給用戶的則為ShowBoard[Row][List],考慮到內(nèi)存的問(wèn)題我們?cè)O(shè)置這兩個(gè)數(shù)組都為char類(lèi)型；

棋盤(pán)的問(wèn)題解決了，那么在用戶第一次選擇坐標(biāo)之前我們還需要1.埋雷；2.把ShowBoard數(shù)組展示出來(lái)，因?yàn)樾枰S機(jī)埋下BoomNumber個(gè)雷所以我們使用隨機(jī)數(shù)的方法，讓系統(tǒng)隨機(jī)產(chǎn)生坐標(biāo)而且不能有重復(fù)的坐標(biāo)，在生成的坐標(biāo)位置埋入Boom，其余位置則為nice（沒(méi)有雷），因?yàn)槁窭资巧贁?shù)操作我們先初始化MineBoard數(shù)組里的元素全為nice；

void SetMine(char MineBoard[][List], int row, int list){	for (int i = 0;i < row;i++)	{		for (int j = 0;j < list;j++)		{			MineBoard[i][j] =nice;		}	}//無(wú)雷為nice	int num = 0;	int _x;	int _y;	while (num < BoomNumber)	{		_x = 1 + rand()%(Row-2);		_y = 1 + rand()%(Row-2);		if (MineBoard[_x][_y] != Boom)		{			MineBoard[_x][_y] = Boom;			num++;		}	}}

埋雷完成后則給用戶展示ShowBoard

void ShowBoards(char ShowBoard[][List], int row, int list){	printf("  ");	for (int x = 1;x < list - 1;x++)	{		printf(" %2d ",x);	}	printf("/n");	for (int i = 1;i < row-1;i++)	{		printf(" %2d",i);		for (int j = 1;j < list-1;j++)		{			printf(" %c |",ShowBoard[i][j]);		}		printf("/n");		printf("   ");		for (int k = 0;k < row - 2;k++)		{			printf("----");		}		printf("/n");	}}

此時(shí)用戶選擇要掃描的坐標(biāo)若該坐標(biāo)沒(méi)有雷則統(tǒng)計(jì)其周?chē)椎膫€(gè)數(shù)，要是有雷則中雷游戲結(jié)束

考慮到用戶輸入的坐標(biāo)可能已經(jīng)被掃描或者用戶輸入的坐標(biāo)不在（1.1）~（Row-2，Row-2）這個(gè)范圍內(nèi)我們就要提醒用戶輸入的坐標(biāo)以及被掃描或者輸入的坐標(biāo)不合法，直到用戶為掃描的坐標(biāo)全為Boom為止

void Select(char ShowBoard[Row][List], char MineBoard[][List], int row, int list){	int step = 0;	int x = 0;	int y = 0;	while (step < ((row - 2) * (list - 2) - BoomNumber))	{		printf("請(qǐng)輸入你要排雷的坐標(biāo):(x,y)/n");		scanf("%d,%d", &x, &y);		if (x > 0 && x < (List-1) && y>0 && y < (List-1))		{			if (ShowBoard[x][y] == 42)			{				if (MineBoard[x][y] == nice)				{					CountBoom(ShowBoard, MineBoard, Row, List,x,y);					system("cls");					ShowBoards(ShowBoard, Row, List);					step++;					if (step == ((row - 2) * (list - 2) - BoomNumber))					{						printf("掃雷成功！/n");						Menu();					}				}				else if(MineBoard[x][y] == Boom)				{					system("cls");					printf("你已經(jīng)被炸死了！游戲結(jié)束/n");					ShowMineBoard(MineBoard, Row, List);				}			}			else {				printf("此處已經(jīng)被掃描,請(qǐng)輸入合法的坐標(biāo)/n");			}		}		else {			printf("請(qǐng)輸入合法的坐標(biāo)/n");		}	}}

統(tǒng)計(jì)用戶選擇的坐標(biāo)的周?chē)椎膫€(gè)數(shù)并讓這個(gè)數(shù)字展示在ShowBoard上，我用到了sprintf函數(shù)來(lái)把數(shù)字轉(zhuǎn)換成字符（因?yàn)槲覀兌xShowBoard數(shù)組為char類(lèi)型）統(tǒng)計(jì)雷的個(gè)數(shù)時(shí)因?yàn)镸ineBoard數(shù)組也是char類(lèi)型在把（x，y）周?chē)?個(gè)位置的雷的個(gè)數(shù)加起來(lái)時(shí)用到的是Boom的ascii碼值，又因?yàn)橛欣诪椤?’（ascii碼值為49）沒(méi)有雷為‘0’（ascii碼值為48）所以在運(yùn)算后需要減去8個(gè)‘0’的ASCII碼值，再返回去看定義這兩個(gè)棋盤(pán)時(shí)我們只需要10x10的棋盤(pán)卻定義了12x12的棋盤(pán)這是為了方便統(tǒng)計(jì)邊緣棋盤(pán)周?chē)椎膫€(gè)數(shù)

void CountBoom(char ShowBoard[Row][List],char MineBoard[][List], int row, int list, int x, int y){	int a = MineBoard[x][y + 1]/		+ MineBoard[x + 1][y + 1] + MineBoard[x - 1][y + 1] /		+ MineBoard[x][y - 1] + MineBoard[x + 1][y - 1] /		+ MineBoard[x - 1][y - 1] + MineBoard[x - 1][y] /		+ MineBoard[x + 1][y] - 384;	char  arr[32];//設(shè)置一個(gè)較大的數(shù)組防止溢出   sprintf(arr, "%d", a);//把數(shù)字轉(zhuǎn)成字符	ShowBoard[x][y] = arr[0];}

至此掃雷游戲的主要邏輯已經(jīng)梳理完畢

#include"FindMine.h"void Menu(){	printf("*****1.開(kāi)始游戲*****/n");	printf("*****2.退出游戲*****/n");	printf("請(qǐng)選擇：/n");	int a = 0;	scanf("%d", &a);	system("cls");	if (a == 1)	{		Game();	}	else if (a == 2)	{		exit(0);	}	else {		printf("輸入有誤，請(qǐng)重新選擇/n");		Menu();	}}void Game(){	char ShowBoard[Row][List];	for (int i = 0;i < Row;i++)	{		for (int j = 0;j < List;j++)		{			ShowBoard[i][j] = "*";		}	}	char MineBoard[Row][List];	SetMine(MineBoard, Row, List);	ShowBoards(ShowBoard, Row, List);	Select(ShowBoard, MineBoard, Row, List);}int main(){	srand((unsigned int)time(NULL));	Menu();	return 0;}

這些為用戶可見(jiàn)的函數(shù)

#include"FindMine.h"void ShowBoards(char ShowBoard[][List], int row, int list){	printf("  ");	for (int x = 1;x < list - 1;x++)	{		printf(" %2d ",x);	}	printf("/n");	for (int i = 1;i < row-1;i++)	{		printf(" %2d",i);		for (int j = 1;j < list-1;j++)		{			printf(" %c |",ShowBoard[i][j]);		}		printf("/n");		printf("   ");		for (int k = 0;k < row - 2;k++)		{			printf("----");		}		printf("/n");	}}void ShowMineBoard(char MineBoard[][List], int row, int list){	for (int i = 1;i < row-1;i++)	{		for (int j = 1;j < list-1;j++)		{			printf("%c", MineBoard[i][j]);		}		printf("/n");	}	Menu();}void CountBoom(char ShowBoard[Row][List],char MineBoard[][List], int row, int list, int x, int y){	int a = MineBoard[x][y + 1]/		+ MineBoard[x + 1][y + 1] + MineBoard[x - 1][y + 1] /		+ MineBoard[x][y - 1] + MineBoard[x + 1][y - 1] /		+ MineBoard[x - 1][y - 1] + MineBoard[x - 1][y] /		+ MineBoard[x + 1][y] - 384;	char  arr[32];//設(shè)置一個(gè)較大的數(shù)組防止溢出   sprintf(arr, "%d", a);//把數(shù)字轉(zhuǎn)成字符	ShowBoard[x][y] = arr[0];}void Select(char ShowBoard[Row][List], char MineBoard[][List], int row, int list){	int step = 0;	int x = 0;	int y = 0;	while (step < ((row - 2) * (list - 2) - BoomNumber))	{		printf("請(qǐng)輸入你要排雷的坐標(biāo):(x,y)/n");		scanf("%d,%d", &x, &y);		if (x > 0 && x < (List-1) && y>0 && y < (List-1))		{			if (ShowBoard[x][y] == 42)			{				if (MineBoard[x][y] == nice)				{					CountBoom(ShowBoard, MineBoard, Row, List,x,y);					system("cls");					ShowBoards(ShowBoard, Row, List);					step++;					if (step == ((row - 2) * (list - 2) - BoomNumber))					{						printf("掃雷成功！/n");						Menu();					}				}				else if(MineBoard[x][y] == Boom)				{					system("cls");					printf("你已經(jīng)被炸死了！游戲結(jié)束/n");					ShowMineBoard(MineBoard, Row, List);				}			}			else {				printf("此處已經(jīng)被掃描,請(qǐng)輸入合法的坐標(biāo)/n");			}		}		else {			printf("請(qǐng)輸入合法的坐標(biāo)/n");		}	}}void SetMine(char MineBoard[][List], int row, int list){	for (int i = 0;i < row;i++)	{		for (int j = 0;j < list;j++)		{			MineBoard[i][j] =nice;		}	}//無(wú)雷為nice	int num = 0;	int _x;	int _y;	while (num < BoomNumber)	{		_x = 1 + rand()%(Row-2);		_y = 1 + rand()%(Row-2);		if (MineBoard[_x][_y] != Boom)		{			MineBoard[_x][_y] = Boom;			num++;		}	}}

以上則為Game函數(shù)中需要調(diào)用的函數(shù)
