Modular programming is a software design technique that emphasizes separating the functionality of a computer program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.

Description

A module interface expresses the elements that are provided and required by the module.

The elements defined in the interface are detectable by other modules. The implementation contains the working code that corresponds to the elements declared in the interface.

Modular programming is closely related to structured programming and object-oriented programming, all having the same goal of facilitating construction of large software programs and systems by decomposition into smaller pieces, and all originating around the 1960s.

While historically usage of these terms has been inconsistent, modern usage is:

  • Modular programming refers to high-level decomposition of the code of an entire program into pieces

Object-oriented programming

In object-oriented programming, the use of interfaces as an architectural pattern to construct modules is known as interface-based programming.
