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...

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...

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...

Introduction to Classes in C++

A class is an organisation of data and functions which operate on them. Data structures are called data members and the functions are called member functions, The combination of data members and member functions constitute a data object or simply an object.

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.

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...

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 the initialization of the different declared member variables of its object.

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....

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++...

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...

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...

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...

Input and Output in C

The standard way of handling all input and output is done with streams in C programming regardless of where input is coming from or where output is going to. This approach has definite advantages for the programmer. A library package has been evolved which is known as...

Arrays in C

What is an Array? In C Programming, an array can be defined as number of memory locations, each of which can store the same data type and which can be referenced through the same variable name. Arrays can be of two types i.e. One Dimensional Array (such as lists) and...

Standard Function Library – ANSI C

The SFL (Standard Function Library) is an open source portable function library for C/C++ programs. Written by iMatix, the SFL provides about 450 functions for compression, encryption, encoding, datatype conversion and formatting, dates, times, calendars, internet programming (MIME, CGI) and many more.

C/C++ String Library

The Better String Library is superior to the C library char string type, or C++’s std::string. It’s safer with regard to buffer overflows, simpler than C string manipulation, works ok for ‘\0’ terminated strings and generally faster for common...

A2FPLOT (Read ASCII data and write in fplot style)

– To configure the program, edit the file “jsconfig.h”. Since this is a general configuration file, not all settings may apply to this package. If in doubt, use grep or anything else to find out if a specific configuration symbol is used somewhere....
