Writing in the front

We have already written three pieces of chess game certainly did not enjoy playing, let’s write a minesweeper game!

@TOC

Know the game

I believe you are familiar with mine clearance! Every computer must have a small game!

The rules of the game

Is in the specified time to bury all the mines found, that is, the game victory!

Victory condition: You need to mark all the mines as quickly as possible without making a mistake, and if you make a mistake, you have to start all over again, so there is a certain element of luck in minesweeper.

Simply put, mark all the places that are not mines, and win the game. If the mark points to mines, the game fails!

How do you find out if it’s not a landmine? Each point opens a small grid, if it is thunder, the game is over, if not, there will be a number, the number of the number of lightning around the circle! 2Denotes the number of mines in the surrounding circle2A. According to these numbers, we can remove all mines and lead to victory!

The game framework

The framework is the same as tic-tac-toe!

// Game frame
	int input = 0;
	do 
	{
		menu();/ / the menu
		scanf("%d", &input); / / select
		switch (input)
		{
		case 1:game();
			break;
		case 0:printf("Quit the game \n");
			break;
		default:printf("Wrong input, please retype \n");
			break; }}while (input);

Copy the code

This is basically how we write small games!

The game to achieve

The implementation of the game is the focus of our game! How do we make it happen? Start with the principle!

• mine

How to buy mine? The minesweeper we play with is a matrix of many small cells! So we can use two-dimensional arrays to bury landmines!

• Displays the number of mines around the point

The calculation of the number of lightning around, is to judge the change point around is not thunder, and calculate the number of display to the player!

• Judge the State of the game

Click on the mines to indicate the end of the game, all mines will be found, the game victory.

The idea of using a two-dimensional array to bury mines and another two-dimensional array to display to the player

When we make thunderAxAThe mine array hides the mine, will find that if we carry out the lookup of the number of mines around is the array out of bounds, so we can create(A+2)x(A+2)A minefield, and then a minefieldAxAIn the!

void game(a)
{
	// Initialize the checkerboard array
	// Set mines -- > Display board -- > Player minesweeper
	/ / mine
	char mine[ROWS][COLS] = { 0 }; / / a minefield
