new to ruby, help with simple output -

i trying learn ruby, , trying exercise on site , need learn ruby

write program asks number , sentence , prints sentence backwards many times. should:

enter image description here

puts "enter number?" repeathello = gets = 0 begin    puts "hello world!" + end while > repeathello

you're making 2 mistakes in code pasted. first need add 1 each time loops. @ moment not increasing in value.

within loop (between begin , end) need increment so:

i += 1

(this shorthand = + 1).

the second mistake on last line. reads 'do while greater repeathello', starts @ 0, not going greater.

you need switch around to

while < repeathello.

you should end code this:

puts "enter number?" number = gets puts "enter sentence?" sentence = gets  = 0 begin   puts sentence.reverse   += 1 end while < number
