PROGRAMING APPROACHES (Lesson 3)

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.
