3. INTRODUCTION
Ruby was created by Yukihiro
Matsumoto, or "Matz", in Japan in the
mid 1990's.

4. HISTORY
 Born Feb 24, 1993 – Yukihiro ”Matz” Matsumoto
 Ruby 0.95 – announced Dec 21, 1995
 – OO, Inheritance, iterators, exception handling, garbage
collection
 Ruby 1.0 – released Dec 25, 1996
 Ruby 1.3 – 1999
 – After its release an English ”Ruby” mailing list was
created
 Ruby on Rails – 2005
 – MVC web framework coded with Ruby
 Ruby 1.9.1 – Latest version

5. OVERVIEW OF RUBY PROGRAMMING
 Ruby – Scripting language, dynamic and object
oriented
 Allows rapid development and rapid prototypes
of software
 Consists of useful string operations and regular
expressions
 Everything in Ruby is an object
 Has automatic garbage collection
 Instant feedback when developing
 Multiple OS support and open source

6. TOOLS NEEDED FOR RUBY
The Ruby interpreter
A text editor such as Notepad++, Scite or
Vim.Word processors such as Wordpad or
Microsoft Word are not suitable.
Command-line access.

7. DIFFERENT FROM OTHER LANGUAGE
 Objects are strongly typed (and variable names
themselves have no type at all).
 No pointers ,no typedefs, sizeof, nor enums.
 There are no header files.
 There’s no #define. Just use constants instead.

8. PROGRAM FOR FACTORIAL NO .
 def fact(n)
if n == 0
1
else
n * fact(n-1)
end
end
puts fact(ARGV[0].to_i)

9. ADVANTAGES
Clean code.
 Easy to learn.
 Documention and support.
Open Source.
 Object oriented.

10. DISADVANTAGES
Ruby's development and updates are
slower.
It is a slower programing language

11. CONCLUSION
 Ruby is an object oriented language and the object oriented
features are used throughout. Ruby is that doesn’t require a lot of
extra punctuation. Compared to Java, Ruby is streamlined, with
less code required to create basic structures such as data fields.
Ruby is a modern language that makes it easy to use high-level
abstractions such as metaprogramming.
