Dear Varun,

maybe something like this ?


def hello(first=nil,second=nil)
	if first.class==Fixnum and second.class==String
		p 'you entered something for both int and string'
	elsif first.class==Fixnum
		p 'you entered something for int'
	elsif first.class==String and second==nil
		p 'you entered something for string'
	else
		p 'come on, read the manual!'
	end
end


p hello(5,'string')
p hello(5)
p hello('string')
p hello(5.78,nil)
p hello()


Best regards,

Axel
