Random Number sorted and drawn as a sign

ErnstPeter (19)
Hi,
i'm trying to programm a game. For that i need random numbers sorted, so the biggest number is first : 31, 32, 41, 42, 43, 51, 52, 53, 54, 61, 62, 63, 64, 65, 11, 22, 33, 44, 55, 66, 21. 21 is game-winning and numbers are allowed only from 1 to 6. It should be outputted in signs.


Heres how far i got:

Sometimes it seems to ignore which number is higher and writes down for example 45 instead of 54.
Is there a smarter way to do it? Mayby a switch case instead of all the if- statements?
Thanks for your answers.

yeah fixed it, sorry for that.

Yes, you should simplify your code following the KISS principle. https://en.wikipedia.org/wiki/KISS_principle

wow, thank you two for the fast answers! :)

Yeah sure, thanks ^^

console_print(w1>w2?w1:w2);
console_print(w1>w2?w2:w1);
rly nice, didnt knew that before. I will definitly use this in the future.

good idea
