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 to the language will be discussed in this chapter […]

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 virtual function to show how it can […]

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…

This concept in C/C++ is called enumeration. Here thisWeek is the variable of enum type week.
Enumerated Types
The enumerated type is used in C++ in exactly the same way it was used in […]

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 variable then we can declare it as

Here var_type is the […]

The Standard C++ Library

The 1998 C++ standard consists of two parts: the core language and the C++ standard library; the latter includes most of the Standard Template Library and a slightly modified version of the C standard library. Many C++ libraries exist which are not part of the standard, such as the Boost library. Also, non-standard libraries written […]

Strings in C++

String in C/C++ is not more than a array of characters. String encapsulates the functionality of traversing, replacing, copying of one character array to another.

One of the biggest time-wasters in C is using character arrays for string processing: keeping track of the difference between static quoted strings and arrays created on the stack and the […]

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++ are very expressive they may be used for things other than generic programming. One such use is […]

Graphics in C Language

In a C language 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 details.
