Ace-High game::user-defined function problems

hello all, i am working on a really simple game that doesn't require any input from the user, except to run or end the program, and i am completely stuck. i could really use some help here.
i have to use user-defined functions and I can't figure out how to call each of them in main().
the program needs to display two cards in numerical form from 2 to 11 for the player and the dealer, then total the two cards. If the player is over 21 he loses, and same for the dealer; but if the dealer is under 17 he must draw again.
the code is below, let me know if i need to give more info(also how do I wrap my code?).
i suggest you read up on functions a little, to call them functions you need to pass values to some of them for example
bool isBust(int hand);
to call this in main you use:
isBust(hand);
where hand would be your stored integer hand value which you would have declared somewhere and set up.
have a look at this:
Function tutorial
hope this helps

I made the game without using anyy functions other than that rand() function you typed.
To practice functions, take the code there and put it into functions and call them when necessary.
(there are a lot of break; calls because without functions, i need to break 3 different loops to exit)
The game works, but can use a touch up with the help of functions...
To the more experienced programmers: I made the game as simple as I could so it would be easy for him to understand... rather than him trying to understand classes + inher.

thanks tommysauder, that helps a lot.
i will practice up on my own functions and using them in main, i tried to give a clean layout of what i was doing instead of all my practice runs with the program.
i really appreciate it, and thanks lonefox1 for the link.
also i might repost it when i get it to work with my functions to have someone review it.

No problem. When you're done putting it in functions I'll look it over for you, thats if none of the more experienced people do it before me!
