Title: Learning about Programming Languages


1
Learning about Programming Languages
  • By
  • Mike and Sean

2
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

5
Object Oriented Ex.
  • public class HelloWorld
  • public static void main(String args)
    System.out.println("Hello, World!")

Article Summary
  • Sorting with column sort
  • Process
  • N r X s
  • RS0
  • 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
