hello I decided to make a little simple 21 game and am stuck on how can i use a variable that stores a random number everytime, for example i set a variable called total= 1+rand()%MAX but each time i call the variable it only gives back the first random number that it gets.
Hmm...I'm slightly confused about your question. Perhaps you mean to use some sort of arrays and/or loops for this.
Use the FAQ, Luke!

My guess is that he's talking about not having used srand properly, and getting the same number every time.
Quzah.
Hope is the first step on the road to disappointment.
for example I need to have random numbers given to the player and the computer (numbers meaning cards). but I cant think of a way to keeping count of the random numbers so that when someone busts over 21 the game can end.Originally Posted by anduril462
The whole point of rand is to give you the next number off the deck. It's your job to put those numbers somewhere, and maybe add them up if you want a total.
yes but how can you add them up? by setting rand equal to a variable and then variable+=variable?
Don't randomly generate cards, instead put all 52 cards in an array in a predetermined order (say by suit, then value), and shuffle the deck, using a shuffling algorithm. Simply count the cards as they're dealt, moving through the array so you know what card you're giving out next.
As for each player's hand, you need to store the cards they've received in an array or linked list. Then, you can write a total_hand() function that goes through the array/list and adds up the total value of the cards. If that value is over 21, you busted. Remember, aces can be 1 or 11, so you'll have to work that in there.
First of all, decks of cards do not lend themselves well to random numbers... every card has to be unique and random numbers do repeat.
Your best bet is to make an array[52] and load each element with it's value... card[0]=0, card[1]=1 etc... in a loop. Then random shuffle the deck.
There are several ways of assigning the values to the cards... for example : card[i] % 13 will give you it's rank in the suit... card[i]/13 will give you the suit... and so on.
nice nice niceee, I was not thinking out of the box what so ever I am definitely going to do it that way, thanks
