i have a program and it works great... the only thing is that i need to add a best hand function... its a poker problem... i need to make a section that stores the best hand and if the hand is beaten it gets replaced... can anyone help me??? the program is at http://www.math.concordia.ab.ca/~mar...2/code/poker.c
thanks
I don't know exactly what you want to store, I just noticed that this thread remained unanswered.
What is the type of information you want to store?
You want this information to be saved or not?
You'd probably get more replies if you posted the code here. Most people don't want to have to click a link to read your code.
Here it is, for reference:

This code is pretty old. It uses the implicit int rule:
This should beCode:main() {
for more recent compilers. Other than that (and maybe Bool) it's good code.Code:int main() {
Have you tried this yet? Or are you hoping we'll write it? :)Quote:
