In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for the ...
In computer programming, a magic number is any of the following: A unique value with unexplained meaning or multiple occurrences which could (preferably) be replaced with a named constant.

Programming language. The source code for a computer program in C. The gray lines are comments that explain the program to humans. When compiled and run, it will give the output "Hello, world!". A programming language is a system of notation for writing computer programs. [1]
The first functioning programming languages designed to communicate instructions to a computer were written in the early 1950s. John Mauchly 's Short Code, proposed in 1949, was one of the first high-level languages ever developed for an electronic computer. [8] Unlike machine code, Short Code statements represented mathematical expressions in ...

Microsoft is starting to introduce managed code application programming interfaces (APIs) for .NET that use this format. One of the first to be generally released is a function to mitigate issues with internationalized domain names , [4] but more are in Windows Vista Beta 1.
The C++ programming language (originally named "C with Classes") was devised by Bjarne Stroustrup as an approach to providing object-oriented functionality with a C-like syntax. C++ adds greater typing strength, scoping, and other tools useful in object-oriented programming, and permits generic programming via templates.
Code reuse. In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software, [1] [2] : 7 following the reusability principles . Code reuse may be achieved by different ways depending on a complexity of a programming language ...
