History of C++


 History of c++ OR What is c++?
o      C++ is object oriented language. It was found in year 1980.
o      It was made by Bjarne Stroustrup at AT & T Bell lab, NJ, USA.
o      C++ contains power of c language as well as it supports object oriented programming features.
o      So c++ is extended c language with classes, so initially c++ was  called as ‘C with classes’.
o      However later in 1983 name was changed to c++.
o      The idea of c++ language is comes from ++ operator of c language, so named given as c++ which suggesting that it is increment version of c.
o      During the early 1990s the language underwent a number of improvements and changes.
o      These changes were made fixed by ANSI / ISO standards committee in November 1997.  It also added several new features to it.
o      C++ is a super set of c. Therefore all C programs are also C++ programs.
o      However there are some minor difference between c and c++.
o      C++ adds some good features that c does not have like classes, inheritance, function overloading, operator overloading etc.
o      C provides us top – down programming while C++ provides us bottom – up programming.
