1. Structured Programming (procedural programming)

• It is based on C language.
• A top-down structure is built around  functions.

(The algorithm can be written by a flow chart.)

• A house is to a blueprint as an object is to a class.
• OOP allows complex programs to be developed using simpler constructions, called objects.
• It is built around classes.
• The relation between class and object is like vehicles and your specific car.
• We learn about things by studying their characteristics and behavior. 
• For example, a class of vehicles:
• Characteristics (attributes, data members): engines, wheels, transmissions, … and so on.
• Behavior (function members): acceleration, deceleration (braking), and turning.
• Abstract data types allow you to work with data objects without concern for how the data objects are stored inside the computer or how the data operations are performed inside the computer.
