[realize the simple version of minesweeping games]

What needs to be done to realize the minesweeping game ？

---

1. First, we will create two two-dimensional arrays , The first one is used to show players for minesweeping , The second array is used to arrange Lei's , This array needs to be expanded by one circle , It is used to prevent several mines near the back calculation from crossing the boundary of the edge position .

2. First initialize the first two-dimensional array to all 0; Then lay thunder on some positions in the second chessboard .

3. How to generate random mines , Here we use srand Function and time Function to complete random values , In order to arrange random thunder .

4. Judge whether the coordinates entered by the player are thunder .

5. How to generate a prompt when the player sweeps to a place that is not a mine? How many mines are nearby .

How to realize , The code is as follows .

（1）.Li.h The header file is used to declare the function .

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

#define ROW 9                                  // That's ok 
#define COL 9                                  // Column 

#define ROWS ROW+2                             // Prevent extra rows from crossing the boundary 
#define COLS COL+2                             // Prevent extra columns from crossing the boundary 

#define EASY_COUNT 10                          // The number of ray 


void init_board(char arr[ROWS][COLS], int rows, int cols, char set);

void show_board(char arr[ROWS][COLS], int row, int col);

void set_mine(char mine[ROWS][COLS], int row, int col);

void find_mine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col);

（2）game.c The source file is used to realize the logic of the game .

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

void game()
{
	// The realization of mine sweeping game 
	char mine[ROWS][COLS] = { 0 };//'0'    	            // It is used to store the information of the arranged mine 
	char show[ROWS][COLS] = { 0 };//'*'                 // Used to store the information of the detected mines 


	init_board(mine, ROWS, COLS, '0');                	// Initialize the chessboard to '0'
	init_board(show, ROWS, COLS, '*');                  // Initialize the chessboard to '*'
	// Arrange thunder 
	set_mine(mine, ROW, COL);
	show_board(show, ROW, COL);
	find_mine(mine, show, ROW, COL);                    // Check the thunder 
}

int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));                           // utilize srand Function and time Function to generate random numbers 
	do
	{
		menu();
		printf(" Please enter -->:");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf(" Quit the game !\n");
			break;
		default:
			printf(" Wrong choice , Please reselect !\n");
			break;
		}
	} while (input);

	return 0;
}

(3).Li.c The source file is used to realize the minesweeping game .

#include "Li.h"

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

void show_board(char arr[ROWS][COLS], int row, int col)                       // Print chessboard 
{
	int i = 0;
	int j = 0;
	printf("-------- Mine clearance -------\n");
	for (i = 0; i <= col; i++)
	{
		printf("%d ", i);
	}
	printf("\n");

	for (i = 1; i <= row; i++)
	{
		printf("%d ", i);
		for (j = 1; j <= col; j++)
		{
			printf("%c ", arr[i][j]);
		}
		printf("\n");
	}
	printf("-------- Mine clearance -------\n");

}

void set_mine(char mine[ROWS][COLS], int row, int col)                    // Arrange thunder 
{                                                                         // Arrange thunder "1" For ray  
	int count = EASY_COUNT;
	int x = 0;
	int y = 0;
	while (count)
	{
		x = rand() % row + 1;                                             // Control the generation range of random numbers 
		y = rand() % col + 1;
		if (mine[x][y] == '0')
		{
			mine[x][y] = '1';                                             
			count--;
		}
	}
}

int get_mine_count(char mine[ROWS][COLS], int x, int y)                 // Check the thunder number 
{
	return mine[x - 1][y] +
		mine[x - 1][y - 1] +
		mine[x][y - 1] +
		mine[x + 1][y - 1] +
		mine[x + 1][y] +
		mine[x + 1][y + 1] +
		mine[x][y + 1] +
		mine[x - 1][y + 1] - 8 * '0';
}

void find_mine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col)             // Investigation results 
{
	int x = 0;
	int y = 0;
	int win = 0;
	while (win < row * col - EASY_COUNT)
	{
		printf(" Please enter the coordinates to be checked -->:");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (mine[x][y] == '1')
			{
				printf(" unfortunately , You're killed in the blast !\n");
				show_board(mine, ROW, COL);
				break;

			else
			{
				int count = get_mine_count(mine, x, y);
				show[x][y] = count + '0';
				show_board(show, ROW, COL);
				win++;

		else
		{
			printf(" Illegal coordinates , Re input \n");
		}
	}
	if (win == row * col - EASY_COUNT)
