C language to achieve mine sweeping game

One 、 The game logic

Before we start , We need to clarify the logic of the game .

Scene arrangement

The game first gives us a square matrix , When we click on one of the grids , This grid will show how many mines are around , We can use a two-dimensional array to store mine information , use 0 It doesn't mean ray ,1 It means ray . such , When we click on a grid , We only detect its surroundings 1 The number of , You can show how many mines it has , But then we will encounter 2 A question

1、 Where is the information of the detected mine , For example, a mine was detected , If stored in the two-dimensional array of Mines , When clicking on the grid adjacent to this grid , This is for storage 1 When I couldn't tell the end, there was a thunder , Or is there a thunder around it .

So we need 2 Two dimensional arrays of the same size , A message for storing thunder , A store of information that users know .

2、 When we click on the side grid , Obviously we can't detect its surroundings 8 Lattice , Because it will cross the border , By this time there are 2 Kind of way , firstly , We can set the detection range , second , We can expand the array by one circle . Here we take the second approach .

With a chessboard , We can initialize them , After initialization, use random number generator to arrange Lei , The stage is basically arranged .

Demining

Next, we start demining , First, we need players to give us a coordinate , To check thunder , When checking Lei, let's first see if this position is Lei , If so, the game is over , If not, it shows that there are several mines around ;

The specific code implementation and some details are put below ,game.h Stored in is the function declaration and macro ,test.c It is the logical implementation of the main program ,game.c Is the specific implementation of the game function .
