Hallo,
I am new to Ruby and I can't solve this Problen.

I've got an Array w with 100 Elements called "w".
I want to divide the array with 1..100 divisors.

i = 0
j = 1.0

w.each do |i|

  while j <= 100.0 do

       print i/j,  ", "


       j +=1.0


 end

end

but it's not working.
Only the first Element of the Array is divided with
the hundred divisors.

I'd be very grateful for help.
Martin

you need to declare "j" inside the "each" loop. By declaring it at the
top, you're reaching j == 100, but you never set it back to 1.

You never reset the value of j to 0, and as such, your inner loop
condition is never true after the first run. Assigning j = 0; in the
outer loop afterward should fix it.

C programming allows to use one loop inside another loop.

Wow. cool post. I’d like to write like this too – taking time and real
hard work to make a great article… but I put things off too much and
never seem to get started. Thanks though. http://supersmashflash-2.com
