sizeofarray
sizeofarray is a term used to describe the memory size, in bytes, occupied by an array’s contents in a given programming language. It is not a universal function name, but the concept appears in several languages in slightly different forms. The precise meaning depends on the language and on how the array is stored and passed around.
In C and C++, for a statically declared array, the operator sizeof yields the total size of
In modern C++, there are safer alternatives. std::size(array) yields the number of elements for fixed-size arrays,
Other languages vary: Python exposes length via len(), but the actual memory consumption includes overhead beyond
