Repeat Method to Give "string" an "x" amounts of times

Question

I'm trying to write a method that will take two arguments, one for the string, and the other the number of times it will be repeated. here is the code of i have:

 def repeat(text,c=2)
   c.times do print text end
 end

 repeat ("hi")

problem here is, I want to have the result to be "hi hi" i tried "puts" but that starts a new line... [ print text " + " text ] doesn't work as well...

thanks for the help!

Answer 1

Your question is unclear. If all you want is to print the text repeated n times, use String#*

def repeat(text, n=2)
  print text * n
end

Your example result says you want "hi hi" implying you would like spaces between each repetition. The most concise way to accomplish that is to use Array#*

def repeat(text, n=2)
  print [text] * n * ' '
end

Answer 2

Simply multiply the string by the number, Ruby is smart enough to know what you mean ;)

pry(main)> "abcabcabc" * 3
=> "abcabcabcabcabcabcabcabcabc"

Answer 3

Or you could do something like:

def repeat(text, c=2)
  print c.times.collect { text }.join(' ')
end

Answer 4

Enumerator#cycle returns an enumerator:

puts ['hi'].cycle(3).to_a.join(' ')

# => hi hi hi

Breaking down the code:

['hi'] creates an array containing a string

cycle(3) creates an enumerator from the array that repeats the elements 3 times

.to_a creates an array from the enumerator so that the join method of Array can create the final output string.
