[C language] Implementing simple mine sweeping (imitation of mine sweeping under Windows)

background

        Personally, I like to play minesweeper, and I happen to be learning the C language, so I want to use my weak C language level to implement a simple minesweeper game. One is to improve your programming level, and the other is to get a different sense of achievement by writing your favorite games.

frame

        The realization of mine clearance is different from the three pieces of chess I wrote before. The function of mine clearance is more complex and more logical.

        I'll start by listing all the modules I can think of:

               Game Implementation Function Menu Initialize Minefield Place Minefield Print Minefield Count Remaining Blocks in Minefield    

               No-mine square expansion function Novice protection function

       Here I have written the outline, and then start to write the supplementary function content.

running result

                                  

        

        But you must have seen it, this small game is only suitable for display, not suitable for playing. (because it's too eye-catching)

       (Also, friends who are interested in improving, please pay attention to my next improvement in minesweeping. I will eventually implement this simple version of minesweeping as a classic minesweeping style under the windows system.)

source code

        The following is the code I wrote. If there are any deficiencies, you are very welcome to point out.

                        (If there is something you don't understand, please ask questions in the comment area)
