Concepts

• Non Object Oriented Programming Lanuage
• Uses top-down programming. This is a programming
  style of traditional procedural languages, in
  which design begins by specifying complex pieces
  and then dividing them into successively smaller
  pieces.
• The technique for writing a program using
  top-down methods is to write a main procedure
  that names all the major functions it will need.
  Later, the programming team looks at the
  requirements of each of those functions and the
  process is repeated.
• Example
• C

Concepts Continued

• Object Oriented Programming Language
• uses "objects" and their interactions to design
  applications and computer programs. Programming
  techniques may include features such as
  information hiding, data abstraction,
  encapsulation, modularity, polymorphism, and
  inheritance.

• Class 
• Object 
• Instance 
• Method 
• Message passing 
• Inheritance 
• Abstraction 
• Encapsulation 
• Polymorphism 
• Decoupling 
• Not all of the above concepts are to be found in
  all object-oriented programming languages, and so
  object-oriented programming that uses classes is
  called sometimes class-based programming. In
  particular, prototype-based programming does not
  typically use classes.
• Example
• C, Java, Python

Object Oriented Ex.

• public class HelloWorld
• public static void main(String args)
  System.out.println("Hello, World!")

• Ex. (r) 9 X (s) 3 matrix
• 9 X 3 27
• 9 3 0

How it works

• Step 1 Sorts the columns
• Step 2 Turns the columns into rows
• Step 3 Sorts the new columns
• Step 4 Turns the rows back into columns
