Question

I am trying to run a simple program:

class Pras
  def samleMethod
    a = 12
    p "a"
  end
end

There are no errors, but why is not output being shown?

Edit

class Pras
  def samleMethod
    a = 12
    p a
  end
end

Answer 1

class Pras
  def samleMethod
    a = 12
    p a
  end
end

In this you are creating a class named Pras with public method named sampleMethod.

I assume you have some knowledge with OOP

so when ever you are accessing a a method you need to create an instance of class to access it.

p =  Pras.new

Now you can access the method using the instance

p.sampleMethod

or both in one line as

  Pras.new.sampleMethod

I would suggest you to have a through look at this tuts. http://www.tutorialspoint.com/ruby/ruby_quick_guide.htm

methods will not be executed unless they are called.
