Sometimes we need to handle limited set of values which can be referred by labels. For example the day of week, year names etc… i.e. enum week{Mon, Tue, Wed, Thu, Fri, Sat, Sun} thisWeek; 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...

Pointers in C++

Posted on September 10th, 2008 10 Comments

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 var_type *varName; Here var_type is the valid C++ Language data...

More on Encapsulation

Posted on September 10th, 2008 0 Comments

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 will be illustrated. Since objects are simply another C++ data construct, all of these things are...

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 variable that represents the location of a data item, such as a variable or an array element. Pointers...

It is a new way of organising and developing programs and has nothing to do with any particular...

Introduction to Classes in C++

Posted on September 10th, 2008 16 Comments

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, etc, is built from assembling various parts. In the same way, C++ allows you to group various...

Posted on September 10th, 2008 19 Comments

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 initializations of the different declared member variables of its object. Unlike some of...

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. C++ Language provides a good mechanism to tacke these conditions. The exception mechanism uses...
