In some programming languages, const is a type qualifier (a Keyword (computer programming), keyword applied to a data type) that indicates that the data is read-only. While this can be used to declare Constant (computer programming), constants, in the List of C-family programming languages, C family of languages differs from similar constructs in other languages in that it is part of the ''type'', and thus has complicated behavior when combined with Pointer (computer programming), pointers, references, composite data types, and type-checking. In other languages, the data is not in a single memory location, but copied at compile time for each use. Languages which use it include C (programming language), C, C++, D (programming language), D, JavaScript, Julia (programming language), Julia, and Rust (programming language), Rust. Introduction When applied in an object (computer science), object Declaration (computer programming), declaration, it indicates that the object is a Consta ...

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...
