Shuffle and Deal Deck of Cards

kske (15)
Can someone look over my code and see if it looks okay. It won't compile for me and I can't figure out what is wrong. It's suppose to randomly assign numbers to an array to simulate a deck and then shuffle them and then deal (output) 13 hands of 4 cards to make sure the random number generator works.

It would be easier if you posted the compiler output in full.

return statements are not needed for void functions.

This is the error message I keep getting:

cards.cpp: In function ‘void display(int*, int)’:

This isn't the full output. We don't actually need the full output, but the first few lines of it would be good. The last lines... not so much.

Nevermind I think I figured it out. I missed a part when i was reading the problem. I was suppose to use the class RandomVariable that we used in another problem.
