C Language to achieve mine sweeping game

Introduction to the rules

I believe many people have played mine sweeping games , But Xiaobian still tells us the rules of this minesweeping game .

This is the first interface of a minesweeping game

Players find all the thunder arranged by the computer in these squares, that is, the game victory , Point to thunder and be killed .
The rules are simple , Now let's start with what we have learned C Language knowledge to achieve it .

C Language code implementation ideas

This program is divided into three parts ,game.h In the file, we write some header files and interface function declarations ,game.c In the file, we write specific interface functions ,test.c Write out the main functions, game menus and other functions in the file .
First we print a game menu

void menu()
{
    
	printf("**********************\n");
	printf("******* 1. play ******\n");
	printf("******* 0. exit ******\n");
	printf("**********************\n");
}

Players choose to enter the game

The following is the specific implementation framework of the game

void game()
{
    
	char mine[ROWS][COLS] = {
     0 };// Store the information of the arranged mine 
	char show[ROWS][COLS] = {
     0 };// Store the information of the detected mine 
	// Initializes the number to the specified element 
	//mine The array is always when there is no thunder ‘0’
	InitBoard(mine, ROWS, COLS,'0');
	//show The array is always ‘*’
	InitBoard(show, ROWS, COLS, '*');
	// Arrange thunder 
	SetMine(mine, ROW, COL);
	// 
	// Print chessboard 
	//DisplayBoard(mine, ROW, COL);
	DisplayBoard(show, ROW, COL);
	FindMine(mine, show, ROW, COL);
}

This is the implementation of the main function

int main()
{
    
	int input=0;
	// Set the starting point for generating random numbers 
	srand((unsigned int)time(NULL));
	do
	{
    
		menu();
		printf(" Please select ：");
		scanf("%d", &input);
		switch (input)
		{
    
		case 1:
			game();
			break;
		case 0:
			printf(" Quit the game \n");
			break;

		default:
			printf(" Input error \n");
			break;

		}
	} while (input);
		return 0;
}

Next, we implement the specific interface function
First, we initialize the chessboard

// Initialize chessboard 
void InitBoard(char board[ROWS][COLS], int rows, int cols,char set)
{
    
	int i = 0;
	int j = 0;
	for (i = 0;i < rows;i++)
	{
    
		for (j = 0;j < cols;j++)
		{
    
			board[i][j] = set;
		}
	}
}

Print chessboard

// Print chessboard 
void DisplayBoard(char board[ROWS][COLS], int row, int col)
{
    
	int i = 0;
	int j = 0;
	printf("----------  The Minesweeper game  --------\n");
	for (j = 0;j <= col;j++)  // Print column number 
	{
    
		printf("%d ", j);
	}
	printf("\n");

	for (i = 1;i <= row;i++)
	{
    
		printf("%d ", i);  // Print line number 
		for (j = 1;j <= col;j++)
		{
    
			printf("%c ", board[i][j]);
		}
		printf("\n");
	}
	printf("----------  The Minesweeper game  --------\n");
}

Arrange thunder

// Arrange thunder 
void SetMine(char board[ROWS][COLS], int row, int col)
{
    
	int count = EASY_COUNT;
	while (count)
	{
    
		int x = rand() % row + 1;
		int y = rand() % col + 1;

		if (board[x][y] == '0')
		{
    
			board[x][y] = '1';
			count--;	
		}
	}
}

 Returns the number of mines around the selected coordinates 

int get_mine_count(char board[ROWS][COLS],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');
}

Check the thunder

void FindMine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col)
{
    
	int x = 0;
	int y = 0;
	int win = 0;// Find the number of non thunder 
	while (win<row*col-EASY_COUNT)
	{
    
		printf(" Please enter the coordinates of the mine to be checked ：");
		scanf("%d%d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
    
			if (show[x][y] != '*')
			{
    
				printf(" The coordinates have been checked , You can't check again ！\n");
			}
			else
			{
     
				// If it's ray 
				if (mine[x][y] == '1')
				{
    
					printf(" unfortunately , You're killed in the blast \n");
					DisplayBoard(mine, ROW, COL);
					break;
				}
				else // If it wasn't ray 
				{
    
					// Statistics mine Array of x y  There are several mines around the coordinates 
					int count = get_mine_count(mine, x, y);
					show[x][y] = count + '0';  // Convert to numeric characters 
					DisplayBoard(show, ROW, COL);
				}
			}
		}
		else
			printf(" The coordinates entered are illegal , Please re-enter ！\n");
	}
	if (win == row * col - EASY_COUNT)
	{
    
		printf(" congratulations , Mine clearance is successful \n");
		DisplayBoard(mine, ROW, COL);
	}
}
