Programming language concepts

classification of data in computer science

in programming languages and type theory, accessing different types using a common interface

storage location paired with a name, which contains a value

technique for creating lexically scoped first class functions

value that gives indirect access to e.g. a variable or register

combination of functions, variables, etc. in a computer program that returns a value

smallest standalone element of an imperative programming language that expresses some action to be carried out

region of a computer program where a name binding is valid

expression in computer science which cannot be evaluated further

programming operation of setting or re-setting the value associated with a variable name

language construct in computer programming for specification of an identifier

In object-oriented programming languages, a mixin (or mix-in) is a class that contains methods for use by other classes without having to be the parent class of those other classes. How those other classes gain access to the mixin's methods depends on the language. Mixins are sometimes described as being "included" rather than "inherited".

character sequence identifying a location in a program's source code

computer programming constraint allowing to bind a symbolic name to an object, valid in a well-defined scope, and to resolve it as a reference by a static or dynamic linking process

token used to name an entity in a computer language

type of C++ reference representing a temporary value
