Rand.Int help

I have two variables that I am giving a random number from 1-13. I want it so that if the first variable is say, 6, the second variable can't be five.

I though of using an 'if' statement, but I just get even more confused.

Use a for loop for your if statement between the two rolls.

code:

%get first randint for loop determining what second randint can't be %get second randint %if the second randint is what it shouldn't be, roll it again (you'll probably want this in a conditional loop)

By the way, what are you using this for?

Whoops, I mean that the second variable can't be the same as the first.

And it's for some blackjack game I gotta do for class.

I want it so that if the first card is Ace of Spades, no other card can be Ace of Spades.

Wow, I feel stupid .

Just get rid of the line:

Thanks, I think I got it.

PC1 and 2 is first and second card.
PC1S and 2S is the first and second suit (1 = Spades, 2 = Hearts, 3 Clubs, 4 = Diamond)

code:

PC1 := Rand.Int (1, 13)     PC1S := Rand.Int (1, 4)     PC2 := Rand.Int (1, 13)     PC2S := Rand.Int (1, 4)     loop         if PC2 = PC1 and PC2S = PC1S then             PC2 := Rand.Int (1, 13)             PC2S := Rand.Int (1, 4)         end if         exit when PC2 not= PC1 and PC2S not= PC1S     end loop

code:

exit when PC2 not= PC1 and PC2S not= PC1S end loop

It should be or, rather than and.

To return to the original question for a moment, there's no need to have a loop. Why would you possibly want to use a loop to generate a second random number when you can do it on the first try?

Say the first roll is 6. The second roll must be one of the set {1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13}. There's 12 digits there. Thus, we can "roll a 12-sided die" and use that value. However, if the value on this roll is a 6, we return 13.

code:

var n := 13 var d1 := Rand.Int (1, n) var d2 := Rand.Int (1, n - 1) if d2 = d1 then     d2 := n end if
