Hi,
Can any one explain about Ruby Datastructure?

Data structures is a generalized name for arrays,hashes,string
Data structures have been invented because simple variables are not enough for solving more complex problems.
Methods are give other names too, such as functions,subprograms or procedures, while in other programming languages there might be several differences between all these, they all mean pretty much the same thing in Ruby, although everyone is trying to using the term "method" only.

Here's how you define a method:

def mymethod
puts "this is my first method"
end

call a method (when you call a method Ruby executes the statements in the method):

by giving it's name:

mymethod
pass arguments to a method

def showme(message)
puts message
end

message="ruby says hello"
showme(message)

You can also use like this
def showme(firstw,secondw)
puts firstw + " " + secondw + "!"
end

showme "Thank","you"

pass a variable number of arguments
def showme(firstw, *therest)
puts firstw + " " + therest.join(" ")
end

showme "Thank", "you", "very", "much!"

Using methods for returning values

def multi(first,second)
first * second
end

multi(2,536)

Return multiple values with a method

def showme()
return “Thank”, “you”
end

array = showme
puts array.join(“ “)

showme

if you want the text to be displayed with spaces between words, assign an array to the method and use the join method on the array.
