The repeat method should take a string, and print it a specified number of times. Use loop and break to complete the method. Be sure to do the following: After printing the value of string, add 1 to the counter variable. Use an if statement together with the break keyword to break out of the loop once counter is equal to times.

loop.rb
def repeat(string, times)
  fail "times must be 1 or more" if times < 1
  counter = 0


  loop do
    print "#{string}" * times
    counter += 1
    if counter == times
      break
    end

  end
end

Hi Carolyn,

Each time through the loop you should only print the string 1 time. But you're multiplying by times and so you're getting too many.

This is how I solved the objective:

def repeat(string, times)

fail "times must be 1 or more" if times < 1

counter = 0

loop do

print string

counter += 1

if counter == times

  break

end

end

end

Thanks, Nick you really helped me with this. I was doing, if counter == 5, instead of, if counter == times. Newbie mistake.

def repeat(string, times) fail "times must be 1 or more" if times < 1 counter = 0 loop do print "#{string}" counter += 1 if counter == times break end end end

I am still very lost on this challenge.


def repeat(string, times) fail "times must be 1 or more" if times < 1 counter = 0


^^The section above confuses me seeing as we have not worked with the keyword "fail" yet^^


loop do print #{string} counter += 1 break if counter == times end


^^The above is my recent effort, but I feel like I am just trying any code and not truely understanding this.

I received this response when running the last code Challenge Bummer: We expected repeat("hi", 5) to print "hi" 5 times, but instead we got ""!
