A c ++ Licensing Program

One, two, three, and four cards are displayed.

The main purpose is to train my card experience (card Recording ability). It may be useful to comrades interested in gambling or bridge.

Compile the file as bd.exe and enter "BD-h" for help.

The following is the source code (for the code for processing command line parameters, refer to VIM ):
