OOP introduction in the first course of programming

Abstract

The paper presents an approach to introduction to Object-Oriented Programming (OOP) on the basis of the Procedural Programming paradigm. It is assumed that the students, to whom the following material is presented, are already familiar with the concept of functions as main building blocks of a computer program, and of course are familiar with the concept of variables and fundamental data types. On this basis, the paper shows how the concept of encapsulation can be presented in the first course of programming.
