C++ Language:The Project I have undertaken is written in C++ Programming language and it supports Object Oriented Programming (OOP).

C++ is an extension C programming language. Bjarne Stoutstrup created it in 1980. It is a deviation form the traditional procedural languages in the sense that it follows OOP.The fundamental idea behind OOP language is to combine both data and its functions into a single unit called object.

An object’s functions,called member functions in C++, typically provide the only way to access its data. If you want to read a data item on an object, you call a member function in an object. It will read the item and return the value to you. You cant access the data directly. The data is hidden, so its safe form the acceidental alteration. Data and its functions are to be encapsulated into a single entity.

Objects provide an approach to program organization, while helping to maintain the integrity of the program data.
