New to Ruby - While loop issues in IRB

Question

So a few days ago I decided I would try and learn Ruby and it\'s actually been going pretty well. I\'ve been mostly fiddling around in IRB until I can find a non-trivial pr

Answer 1

Unless your purpose is specifically to understand how while loops and integer addition/comparison work, what you really want is

1000.times do |i|
end

Answer 2

Ruby doesn't have C-style increment (++) or decrement (--) operators. You want this:

i = 0
while(i < 1000)
  i = i + 1 # Or i += 1
end

Answer 3

i++ is not valid ruby. You need to do i += 1.

Edit: See Mladen's comment as to what the parser is seeing.
