Writing One's Own Methods in Ruby

What have I found out so far?

• Definition of Ruby
• Ruby Windows Installer
• Interactive Ruby - Open a new DOS window and type irb --simple-prompt A prompt appears as >>
• Run a Ruby program by typing ruby hello.rb
• Learnt some features of Ruby like comments, naming rules, variables, constants, strings etc.
• Various Text Editors/IDEs like SciTE, NotePad2
• Constructs like the if else and while
• Some methods in Ruby.
• Arrays

Today, I am going to look at writing one's own methods in Ruby.

Let us look at a simple program.

# A simple method
def hello
  puts 'Hello'
end
#use the method
hello
# Method with an argument
def hello1(name)
  puts 'Hello ' + name
  return 'success'
end
result = hello1('satish')
# Check the return value
puts result
