Everyone knows that memory management is a difficult and dangerous chore in C++. This series of three articles will show you that the conventional wisdom is not true. When approached correctly, C++’s seemingly archaic memory-management scheme actually provides an opportunity to create spectacular programs – programs that would not be possible with more modern languages that handle memory automatically.

As we begin the study of C++ and object oriented programming, a few comments are in order to help you get started. Since the field of object oriented programming is probably new to you, you will find that there is a significant amount of new terminology for you to grasp. This is true of any new endeavor and you should be warned not to be intimidated by all of the new concepts.

Encapsulation is a fundamental concept in Object Oriented Programming (OOP) that involves bundling data (attributes) and methods (functions) into a single unit known as a class. This encapsulated unit acts as a self-contained module which enhances code organization and promotes a more intuitive and manageable structure for programmers.

Functions are the building blocks of any programming language. In C++, a function is a block of code that performs a specific task. Think of it as a mini-program within your main program, designed to execute a particular operation. Functions are like building blocks that help break down complex problems into manageable chunks, making your code more readable and modular.

Virtual functions enable redefinition of a base class function in derived classes using the “virtual” keyword. They allow dynamic selection of the appropriate function at runtime based on the object’s actual type.

Multiple Inheritance in C++ is a powerful yet intricate feature that allows a class to inherit properties and behaviors from more than one base class. In traditional single inheritance, a class can have only one immediate parent, but with multiple inheritance, a derived class can inherit from multiple base classes.

While grasping the fundamentals of encapsulation is crucial, delving into advanced concepts and patterns elevates code design and maintainability further in C++. In this article, we will explore sophisticated aspects of encapsulation that go beyond the basics and provides you with a deeper understanding of its applications and impact on software development.

The pointer is a variable which holds the memory address of another variable. If one variable contains the address of another variable, the first variable is said to point to the second. There are two types of pointer operators; * and &. the & is a unary operator that returns the memory address of its operand.
