A dynamic programming language is a type of programming language. It allows various operations to be determined and executed at runtime. This is different from the compilation phase. Key decisions about variables, method calls, or data types are made when the program is running. Unlike static languages, the structure and types are fixed during ...
In object-oriented (OO) and functional programming, an immutable object (unchangeable [1] object) is an object whose state cannot be modified after it is created. [2] This is in contrast to a mutable object (changeable object), which can be modified after it is created. [3] In some cases, an object is considered immutable even if some ...
Coupling (computer programming) In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are; [1] the strength of the relationships between modules. [2] Coupling isn't binary but it's multi-dimensional. [3] Coupling is usually contrasted with cohesion.
Polymorphism. In software engineering, double dispatch is a special form of multiple dispatch, and a mechanism that dispatches a function call to different concrete functions depending on the runtime types of two objects involved in the call. In most object-oriented systems, the concrete function that is called from a function call in the code ...
Control flow. v. t. e. In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
From a dynamic programming point of view, Dijkstra's algorithm for the shortest path problem is a successive approximation scheme that solves the dynamic programming functional equation for the shortest path problem by the Reaching method. [7] [8] [9] In fact, Dijkstra's explanation of the logic behind the algorithm, [10] namely Problem 2.
Objective-C. Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk -style messaging to the C [ 3] programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system.
Multiple dispatch. Predicate dispatch. v. t. e. In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation ( method or function) to call at run time. It is commonly employed in, and considered a prime characteristic of, object-oriented programming (OOP) languages and systems.
