Need help with Containers

angryplayer557 (15)
I need help on creating a container in an already working program. What I already have is a poker hand stating that I have three numbers that the user inputs that says you have three (number or face card), you have a pair, you have a high-straight, or you have high card. Now my professor is asking us to do add another hand that states three cards and having the first hand beat, lose, or tie the second hand. He wants us to seperate the functions in a header file and the rest to do like normal. But i'm confuse on where to start on the existing program.
