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...

Pointers

Each memory location that we use to store the data hase an address in computre memory (RAM). Computer Hardware i.e. CPU uses this addess to reference to a particular data item. A pointer is a variable that stores the address of another variable. A pointer is a...

C++ and Object Orientation

Object- Oriented Programming (OOP) is an approach to program organization and development that attempts to eliminate some of the pitfalls of conventional programming methods by in incorporating the best of structured programming features with several powerful new...

Introduction to Classes in C++

The data types we have applied so far to our variables were used to identify individual items. To create more advanced and complete objects, C++ allows you to group these identifiers and create a newly defined object. An object, such as a CD Player, a printer, a car,...

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...

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....

Operators Overloading

What is Operator Overloading Operator Overloading enables us to make the standard operators, like +, -, * etc, to work with the objects of our own data types. So what we do is, write a function which redefines a particular operator so that it performs a specific...

Advance Exception handling

An exception usually signals an error. Thought it doesn’t always indicate an eror, it can also signal some particularly unusual even in your program that deserves special attention. Exception & Errors Handling No mater how good our program is, it always have...
