In order to realize the progress of the game of backgammon, there are the following steps:
First of all, we need to design a simplified menu for users to choose to enter the game.
Secondly, if the user enters the game, the writing and implementation of the chessboard is first required.
The user then plays chess and proceeds to print a new board.
The computer generates random numbers to play chess, and continues to print new chessboards.
Determine whether the computer wins the player to win a tie or continue playing.
So far we have completed an idea of a three-moon chess program, the core of which is the application of two-dimensional arrays. Since I find it troublesome, I put all the three-moon chess programs in a source file and implement them through the definition of macros. The checkerboard with m rows and n columns is no longer limited to a chessboard with three rows and three columns in terms of judgment conditions. And backgammon just add two more equal

The code looks complicated, but it is actually not difficult to understand. Just pay attention to the relative relationship between the arrays. This is just a basic game of backgammon. Of course, the above code can be optimized.
If there are any mistakes or bad writing, please correct me.
