LESSON 3 : PROGRAMING APPROACHES

STRUCTURED PROGRAMMING EDUCATION

Structured programming often uses a top-down design model where

developers map out the overall program structure into separate subsections

from top to bottom.

In the top-down design model, programs are drawn as rectangles. A top-down design means that the whole program is broken down into smaller sections that are known as modules.A program may have a module or several modules.

Structured programming is beneficial for organising and coding computer

programs which employ a hierarchy of modules. This means that control is passed downwards only through the hierarchy.

Examples of structured programming languages include Ada, Pascal and

Fortran.

OBJECT-ORIENTED PROGRAMMING

The object-oriented approach refers to a special type of programming approach that combines data with functions to create objects.

In an object-oriented program, the object have relationships with one another.

One of the earliest OOP languages is Smalltalk. Java, Visual Basic and C++ are examples of popular OOP languages.  

DIFFERENCE BETWEEN STRUCTURED AND OBJECT ORIENTED PROGRAMMING

•       Structured programming often uses a top-down design model.
•  The object-oriented programming approach uses objects.
