What’s new in C++?

As we begin the study of C++ and object oriented programming, a few commentsare 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...

Encapsulation

Object oriented programming is a new way of approaching the job of programming. Object oriented programming will seem very unnatural to a programmer with a lot of procedural programming experience. This tutorial is the beginning of the definition of object oriented...

Functions in C++

Functions are the building blocks of any programming language. A Function is a self contained block of code with a specific purpose. It has a name that is used to identify and call it for execution. The function name is global, but it is not necessarily unique in C++....

Virtual Functions in C++

Once again we are into a completely new topic with terminology which will be new to you. If you are new to object oriented programming, you should follow along in this tutorial very carefully because every attempt has been made to define every detail of this new and...

More on Encapsulation

The purpose of this tutorial is to illustrate how to use some of the traditional aspects of C or C++ with classes and objects. Pointers to an object as well as pointers within an object will be illustrated. Arrays embedded within an object, and an array of objects...

Multiple Inheritance in C++

C++ version 2.0 was released by AT&T during the summer of 1989, and the major addition to the language is multiple inheritance, the ability to inherit data and methods from more than one class into a subclass. Multiple inheritance and a few of the other additions...

Generic containers

Container classes are the solution to a specific kind of code reuse problem. They are building blocks used to create object-oriented programs?they make the internals of a program much easier to construct. A container class describes an object that holds other objects....

More on Virtual Functions in C++

This tutorial will actually be a continuation of the topics covered in the last tutorial of Virtual Functions but this will be a fuller explanation of what virtual functions are and how they can be used in a program. We will present a simple database program with a...

Compounded Types in C++

Sometimes we need to handle limited set of values which can be referred by labels. For example the day of week, year names etc… C i.e. enum week{Mon, Tue, Wed, Thu, Fri, Sat, Sun} thisWeek; 1 i.e. enum week{Mon, Tue, Wed, Thu, Fri, Sat, Sun} thisWeek; This...

Pointers in C++

We can say the pointer as 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. Declaring a Pointer If a variable is holding the address of another...

Constructors in C++

A constructor is a special method that is created when the object is created or defined. This particular method holds the same name as that of the object and it initializes the instance of the object whenever that object is created. The constructor also usually holds...

Destructors in C++

As opposed to a constructor, a destructor is called when a program has finished using an instance of an object. A destructor does the cleaning behind the scenes. Like the default constructor, the compiler always create a default destructor if you don’t create...
