From C to C++ – What’s new?

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

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...

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...

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… 1 i.e. enum week{Mon, Tue, Wed, Thu, Fri, Sat, Sun} thisWeek; This concept in C/C++ is called enumeration. Here thisWeek is the...

Pointers in C++

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.

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...

Exception Handling

Exceptions are the way of flagging unexpected conditions or errors that have occured in C++ program. Exception Mechanism so far we have handled error conditions by using the if statement to test some expressions and then executing specific code to deal with the error....

Operator Overloading in C++

Operator Overloading enables us to make the standard operators, like +, -, * etc, to work with the objects of our own data types or classes. We can write a function which redefines a particular operator so that it performs a specific operation when it is used with the object of a class.
