Print contents of array in oneline

I am new to ruby and was trying out with arrays.i want to print the array in single line. this is the block of code(please ignore any errors)

array=[]

puts "Choose an option: ","1.Push, 2.Pop, 3.Display Length"
choice=gets.to_i
while choice!=4
if choice==1
    puts "enter Number of elements to be pushed"
    n=gets.to_i
    n.times do
      puts "Enter element"
    el=gets.to_s
    array.push el
    end
  puts array
elsif choice==2
    puts array.pop

elsif choice==3
    puts array.length

else
  puts "invalid"
end
end

when I print my array in if choice==1i get all the outputs on different lines, example

hello
i
am
beginner
to
ruby

is there anyway to put the output in single line? i.e hello i am beginner to ruby

EDIT: I have even tried using puts array.join(' '), but that too doesnt work.

New to Ruby as well! I just tried:

puts "#{array.inspect}"

where array = [2 3 4 5 6 77 88]. It resulted in:

["2", "3", "4", "5", "6", "77", "88"]

which is a single line printout, if a quick fix is needed. But array.join(' ') is much better.

Instead of puts array try p array if you want the whole array printed to screen.

First of all,

puts array

should be

puts array.join(' ')

By default, puts outputs each element on its own line.

Secondly,

el=gets.to_s

should be

el = gets.chomp

gets returns a string, so there's not much point in converting a string to a string. But the string returned by gets will also end with a newline, so you need to chomp that newline off.
