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.
First of all,
puts array.join(' ')
puts outputs each element on its own line.
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.
puts array try
p array if you want the whole array printed to screen.
New to Ruby as well! I just tried:
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.
