Lets get started 

Inputs

Inputs are of two types:

1. Compile time (Defined)

1. Run time(Uses defined)

Simple code to print hello world.
puts "Hello world"

Printing Hello World

puts "Hello world"
Here we can see printing anything in ruby is very easy by giving  puts  before the statement.

Getting input from the user.

Getting input is  nothing but getting the input from the user. 
To get input from the user in ruby language we want to write as gets.chomp and to print into output screen we need to give puts "#{}

a=gets.chomp
program:
a=gets.chomp
puts "#{a}"
