Abstraction is a mechanism to’ hide irrelevant details and represent only the essential features so that one can focus on important things at a time; It allows managing complex systems by concentrating on the essential features only. For example, while driving a car, a driver only knows the essential features to drive a car such as how to use clutch, brake, accelerator, gears, steering, etc., and least bothers about the internal details of the car like motor, engine, wiring, etc. [Read more…] about What is Abstraction?

Write a C++ program to Operator Overloading Using a Friend Function.
A feature of some programming languages in which the same 0PERATORmay be used on different data types with different, but analogous, results. For example most languages permit the same operator + to add either INTEGER or FLOATING-POINT numbers, and many further allow it to be used to CONCATENATE strings, so that ‘rag’ + ‘mop’ produces ‘ragmop’. A few languages, including C++, allow the programmer to create new operator overloading. [Read more…] about Write a C++ program to Operator Overloading Using a Friend Function.
