Re: For loops trouble

I am trying to translate a program I have in Java into ruby and having
trouble translating this for loop
for(int i = 0; a[i] < x;i++)
I tried this
for i in a[i]...x
but it produce some errors. Any help will be appreciated. Thank you.

Ruby has a for-in loop:

a = [2, 4, 1, 9, 6]
x = 7

for num in a
break if num > x
puts num
end

But a for-in loop calls each(), so ruby programmers just use each()
directly:

a.each do |num|
break if num > x
puts num
end
