File Handling in C Programming

This article is about file handling using C programming language. File stores information for many purposes and retrieve whenever required by our C programs. A file represents a sequence of bytes on the disk where a group of related data is stored. File is created for permanent storage of data. C programming language can handle files as Stream-oriented data (Text) files and System oriented data (Binary) files.

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...

Object Oriented Programming Techniques

Any program which uses these five methodologies or any of it, we can call that program object oriented. They are Encapsulation, Data Hiding, Overloading, Polymorphism, Inheritance. Any programming language which supports all of these features and facilitate the programmer in developing the program in these methodologies is called Object Oriented Programming Language i.e. C++, Java, C#.

The Art of Computer Virus Research and Defense

The Art of Computer Virus Research and Defense is a reference written strictly for white hats: IT and security professionals responsible for protecting their organizations against malware. Peter Szor systematically covers everything you need to know, including virus behavior and classification, protection strategies, antivirus and worm-blocking techniques, and much more.

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...

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...

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. Container classes are so important that they were considered fundamental to early object-oriented languages

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.

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...

Working with Pointers in C

A pointer is a variable that represents the location of a data item, such as a variable or an array element. Pointers are used frequently in C, as they have a number of useful applications. For example, pointers can be used to pass information back and forth between a function and its reference point. Pointers provide a way to return multiple data items from a function via function arguments to
be specified as arguments to a given function.
