First of all, you should fix that...

Code:

main.c:26: warning: return type of `main' is not `int'
main.c: In function `main':
main.c:37: warning: array subscript has type `char'
main.c: In function `shuffledeck':
main.c:93: warning: implicit declaration of function `rand'
main.c:100: warning: statement with no effect
main.c: In function `dealdeck':
main.c:121: warning: unused parameter `deckptr'
main.c:121: warning: unused parameter `handsDelt'

In the mean time, I will check your code more deeply...

Ok. In main(), the pointer in unchanged in the loop. Fix that.

Note also that the caracters 3 to 6 may represent Heart, Spade etc, or not. It depends on the system.

No need to check deeply. They don't seed rand. I suggest reading the FAQ entry on random number genneration. Or perhaps simply searching the forum. (Hint: srand)

Quzah.

The last two should be obvious: You don't do anything in the function, and just like the warning says, those arguments aren't being used.

The function should be easy. Just write out the steps you yourself would take to deal a hand of cards. Break each step down into smaller and smaller pieces, and then turn it into code.


Quzah.

What exactly are you stuck with? I don't think anyone is going to write the whole thing for you, it would defeat the purpose of trying to learn the language.

deckptr -> faceValue = y;
}
deckptr++;

only fills the deck with 4 cards.

Have a think about how often you call deckptr++;

Not a very good solution. Seriously, just think out how you deal cards.

Code:

while you haven't dealt enough cards:
    for each player:
        take one card off the pile and give it to the player

Really, was it that confusing? That's why I said: Write down what YOU would do to deal cards.

okay so heres what i have and this isnt running at all rite now

Code:

   and pointers. */

What do you meant here ? It's not C.

Code:

	for(x=3;x<7;x++)
	{
		for(y=2;y<15;y++)
		{
			deckptr -> suitValue = x;
			deckptr -> faceValue = y;
		}
		deckptr++;

Don't you read the advices you received? This deckptr++; is not at the right place. Shake your brain!

Code:

		deckptr + 1;

What is this ?

Do you meant

Code:

		deckptr++;
