C++ is programming language developed by Bjarne Stroustrup at Bell Labs since 1979, as an extension of the C programming language, or “C with Classes”. The language has expanded significantly over time, and modern C++ has object oriented, generic, and functional features in addition to facilities for low-level memory manipulation.
C++ is considered to be an intermediate-level language, as it encapsulates both high- and low-level language features. Initially, the language was called “C with classes” as it had all the properties of the C language with an additional concept of “classes.” However, it was renamed C++ in 1983. It is pronounced “see-plus-plus.”
The main highlight of C++ is a collection of predefined classes, which are data types that can be instantiated multiple times. The language also facilitates declaration of user-defined classes. Classes can further accommodate member functions to implement specific functionality. Multiple objects of a particular class can be defined to implement the functions within the class. Objects can be defined as instances created at run time. These classes can also be inherited by other new classes which take in the public and protected functionalities by default.
C++ includes several operators such as comparison, arithmetic, bit manipulation and logical operators. One of the most attractive features of C++ is that it enables the overloading of certain operators such as addition.
