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...

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....

Templates in depth

Templates are of great utility to programmers in C++, especially when combined with multiple inheritance and operator overloading. The C++ Standard Template Library (STL) provides many useful functions within a framework of connected templates. As the templates in C++...

Graphics in C Language

In a C program, first step is to initialize the graphics drivers on the computer. This is done using the initgraph() method provided in graphics.h  library. In the next few pages we will discuss graphics.h library in more details. Important functions in graphic.h ...

Generic algorithms

Algorithms are at the core of computing. To be able to write an algorithm once and for all to work with any type of sequence makes your programs both simpler and safer. The ability to customize algorithms at runtime has revolutionalized software development. The...

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...
