How do I return a variable from a Ruby method? -

what's best way return value of 'hash' variable?

define_method :hash_count    char_count = 0   while char_count < 25      hash = ''     hash << 'x'     char_count += 1   end end 

you have define hash outside loop. if it's inside keep resetting on every iteration.

define_method :hash_count    char_count = 0   hash = ''   while char_count < 25     hash << 'x'     char_count += 1   end   hash # returns hash method end 

by way, don't have keep track of char_count. check length of string:

define_method :hash_count    hash = ''   hash << 'x' while hash.length < 25   hash # returns hash method end
