Subject: Re: Remove vowels from a string

Hi,

Or a bit more straightforward:

str.delete 'aeiouAEIOU'

Ruby is not Java or C! You should get rid of this lowlevel programming 
style and take a more highlevel approach.

It's very rare in Ruby that you actually have to build a string 
character by character in a loop. There's almost always a more 
intelligent way to do this (like String#delete or String#gsub in this 
case).

Apart from that, you shouldn't use the "for" loop. It's just ugly and 
has the disadvantage of not creating a new scope (i. e. the loop 
variable is accessible from the outside). Use an iterator like 
String#each_char.
