A Brief History of C++

The C++ Programming Language is basically an extension of the C Programming Language. The C Programming language was developed from 1969-1973 at Bell labs, at the same time the UNIX operating system was being developed there. C was a direct descendant of the language B, which was developed by Ken Thompson as a systems programming language for the fledgling UNIX operating system. B, in turn, descended from the language BCPL which was designed in the 1960s by Martin Richards while at MIT.
In 1971 Dennis Ritchie at Bell Labs extended the B language (by adding types) into what he called NB, for "New B". Ritchie credits some of his changes to language constructs found in Algol68, although he states "although it [the type scheme], perhaps, did not emerge in a form that Algol's adherents would approve of" After restructuring the language and rewriting the compiler for B, Ritchie gave his new language a name: "C".
In 1983, with various versions of C floating around the computer world, ANSI established a committee that eventually published a standard for C in 1989.
In 1983 Bjarne Stroustrup at Bell Labs created C++. C++ was designed for the UNIX system environment, it represents an enhancement of the C programming language and enables programmers to improve the quality of code produced, thus making reusable code easier to write.
