eight , All codes
one , menu bar
1. Make a simple version of the menu , And attach option tips
2. Because the program wants to run at least once , For all selections do while loop , When choosing to play or not to play games , Then use switch case The statement is more appropriate , Then you can call the corresponding function.
two , Initialize chessboard
1. First create a chessboard
To make it easier to change the size of the chessboard , All macro definitions are used to define their rows and columns
2. Initialize the chessboard
When not playing chess at first , The chessboard should be blank , All initializes all its elements to spaces
three , Print chessboard
four , Players play chess
Because the player doesn't know that the array subscript is 0 start , All in use checkerboard array , Both rows and columns should -1
While playing chess , There may be wrong coordinates or pieces in the coordinates written , All use cycle
five , Computer chess
Computer chess adopts the method of random number , You need to use the function of timestamp and random number :rand(),time() Two functions , And call rand() Function needs to be called srand() function
Due to the uncertainty of random number , All adopt the method of taking mould , Change its range to the range of row and column markers of chessboard array
Because I don't know if there are chess pieces where I play chess , The same cycle is adopted
six , Judge whether to win or lose
1. Four results to judge whether to win or lose
If the player wins —— return '*'
If the computer wins —— return '#'
If there is a draw —— return 'Q'
The game continues —— return 'C'
2. Judge whether the rows are equal
3. Determine whether the columns are equal
4. Judge whether the diagonal lines are equal
If the chessboard is large , It needs to be judged in a circular way
5. When judging a draw or the continuation of the game, it depends on whether the chessboard is full
seven , Call player , Computer chess function and judgment function
Because playing chess is a multi-step operation , All use cycle
The chessboard should be printed for each move , It also determines whether the game needs to continue , Don't continue , Then jump out , Judge whether to win or lose
eight , All codes
