Questions tagged [abstraction]

Abstraction is a computer science concept in which an implementation is separated from its interface.

Abstraction is a computer science concept in which an implementation is separated from its interface. Abstraction allows an implementation to be modified without changing the interface, so that other code which relies on this interface does not have to be modified.

For instance, a function prototype in C would be considered the function's interface, and its definition is considered the implementation. The function definition can change (for instance, to improve performance or fix a bug), but as long as the function signature (as specified by the prototype) is the same, any code calling the function can remain the same.
