C++ is a general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming.
C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.
C++ was developed by Bjarne Stroustrup of AT&T Bell Laboratories in the early 1980’s, and is based on the C language. The “++” is a syntactic construct used in C (to increment a variable), and C++ is intended as an incremental improvement of C. Most of C is a subset of C++, so that most C programs can be compiled (i.e. converted into a series of low-level instructions that the computer can execute directly) using a C++ compiler.
C++ is a superset of C, and that virtually any legal C program is a legal C++ program.
C++ fully supports object-oriented programming, including the four pillars of object-oriented development:
– Data hiding
Use of C++
– C++ is used by hundreds of thousands of programmers in essentially every application domain.
– In Adobe Systems All major applications are developed in C++: Photoshop & ImageReady, Illustrator, Acrobat, InDesign, GoLive
– C++ is widely used for teaching and research because it is clean enough for successful teaching of basic concepts.
– Anyone who has used either an Apple Macintosh or a PC running Windows has indirectly used C++ because the primary user interfaces of these systems are written in C++.
– Amazon.com, Facebook, Google, HP, IBM, Microsoft, Mozilla, Nokia & many more companies uses C++ language.
