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 concepts. It is a new way of organising and developing programs and has nothing to do with any […]
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 […]
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 […]
Exceptions are the way of flagging unexpected conditions or errors that have occured in C++ program.
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
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 one. Like the default constructor, a destructor also has the same name […]
What is Operator Overloading
Operator Overloading enables us to make the standard operators, like +, -, * etc, to work with the objects of our own data types. So what we do is, write a function which redefines a particular operator so that it performs a specific operation when it is used with the object of […]
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 to be able to handle possible errors. Most applications today contain some form of error […]
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 […]
