Rand.Int

[Azzy]

how can you make it so it can only use one number one time?

[Mazer]

could you explain what you mean?

[poly]

I think he means, have say a randint randomizing from 1 to 6 and only having 1 show up once, 2 show up once etc.

[Azzy]

exactly like poly said.like for the one i'm doing i have 52 but each one can only show up once.so there can only be 1 of the 35 variable in the array.

[poly]

ok so have the randint and have an array keeping track of the numbers and have either an array or variable making sure no numbers are the same. I understand what you mean and how to do it, just I am shitty at explaining things just like above!

What you should do is to have an array 1 to w/e largest number you want. Then you use Rand.Int to randombly pick an index of the number. It will be your first result. Then take that array element out and shift the array so that there're no gaps.

So each time, you pick a random number from 1 to n-try.

Like tony said create an array
but create an array 1 to the highest num of boolean

and put the randint inside a loop
when a random number is choosen go to the array of that number and set it to true. and then exit the loop. If the array is allready true then have it pick another number

var Array : array 1 .. 6 of boolean init(false,false,false,false,false,false)
var num : int
loop
randint(num,1,6)
if not (Array(num)) then
Array(num) = true
exit
end if
end loop
%Then do what ever you have to do

bad nis tsk tsk tsk

you got it all wrong. You suppost to generate a number number just once, not untill you pick one that wasn't used. What if it's a 1000 numbers to be generated? You'll have a 1/1000 chance of getting that last number and it will take you a LONG while.

here's my code:

code:

var randN:int %just to hold the number var numbers:array 1..10 of int for i:1..10 numbers(i):=i end for for decreasing i:10..1 randN := Rand.Int(1,i) put numbers(randN)     if randN not=i then     for a:randN+1..i     numbers(a-1):=numbers(a)     end for     end if end for

damn


That is good code

*cough* Watch your back *cough*

Showing me up like that

[Tony]

heh sorry nis

[Azzy]

There was a problem with the code.That is for an int array but I need that code for a string array.Is there any way you can change that?

[Tony]

You asked for numbers.

use one number one time

ether way. You get a list of numbers - use them as your array indexes to pick stings out.
