Your sig says you are studying Comp Sci and engineering.
You have posted the code for what is really a very, very, small program.
In the real world you will be expected to read and understand much
bigger programs than this - think about 1000+ files and half a million
lines of code.... (That was my first post uni' project - in C)
You apparently want us to read this code and interpret it for you?
Please try reading it and figuring out how it works first, then if you
have sections you want help with, come back and ask specific
questions. Don't expect us to do something you are not willing
to at least make a start on...

Here is the code of this game. I want to change some part of them.
1. Since I don't know what part of code is "responsible" for the
number of cards, so I don't know how to add a "card number check"
attribute, I mean, to check the number of card is more enough for next
time play no matter how many players there are, if cards are not more
enough, print out a notice and stop the program;
2. I am not sure if I can let the winner get all of the cards and
print out what cards the winner has when the game finished.
Thank you!
