• is the principle of design and developments of programs using modular approach. Object Oriented Programming
• Focuses on processing of instructions in order to perform a desired computation. Procedural Programming
• a concept that combines both the data and the functions that operate on the data into a single unit called the object. Object oriented programming
• a collection of data members and associated member functions. Object
• is a collection of objects that have identical properties, common behavior and shared relationship. class
• refers to the process of representing essential features without including background details or explanations. Data abstraction
• The wrapping of data and functions into a single unit (class). Data encapsulation
• a method used in oop to hide information within computer code. Data hiding
• the process by which one object can acquire and use the properties of another object. Inheritance
• allows objects to have different meaning depending upon context. Overloading
• Two types of overloading. Operator overloading and Function overloading
• When an existing operator operates on new data type is called operator overloading
• it means two or more function have same name, but differ in the number of arguments or data type of arguments. Function overloading
• The ability of an operator and function to take multiple forms is known as Polymorphism
• is the process of connecting one program to another. Binding
• is the process of linking the procedure call to a specific sequence of code or function at run time or during the execution of the program. Dynamic binding
• involves specifying the name of the object, the name of the function and the information to be sent. Message passing
• Advantage's of OOP highlighted keywords only:

  classes

  objects

  code duplication

  code reusability

  Data encapsulated
• Applications of OOP's:

  Computer graphics applications

  CAD/CAM software

  Object-oriented database

  User-interface design

  Real-time systems

  Simulation and Modeling

  Artificial Intelligence and expert systems
