Static memory allocation refers to the process of allocating memory at compile-time before the associated program is executed, unlike dynamic memory allocation or automatic memory allocation where memory is allocated as required at run-time. In computer science, dynamic memory allocation is the allocation of memory storage for use in a computer program during the runtime of that program. ... It has been suggested that this article or section be merged with Function stack. ...

An application of this technique involves a program module (e.g. function or subroutine) declaring static data locally, such that these data are inaccessible in other modules unless references to it are passed as parameters or returned. A single copy of static data is retained and accessible through many calls to the function in which it is declared. Static memory allocation therefore has the advantage of modularising data within a program design in the situation where these data must be retained through the runtime of the program. In computer science, a subroutine (function, method, procedure, or subprogram) is a portion of code within a larger program, which performs a specific task and is relatively independent of the remaining code. ... In computer programming, a parameter is a variable which takes on the value of the corresponding argument passed in the call to a subroutine. ...

The use of static variables within a class in object oriented programming enables a single copy of such data to be shared between all the objects of that class. In computer science, object-oriented programming, OOP for short, is a computer programming paradigm. ...
