Too Long; Didn't Read
A fixed (or fixed-size, fixed-length) array is an array that has a max amount of items. Some languages, such as C, Objective-C, and C++, use fixed arrays, while more modern languages use arrays that aren’t set in size. Fixed arrays are used when programmer knows how many elements an array should hold. They leave room for overflow errors and are generally not a flexible data structure. The good thing about these types of arrays is that they are predictable and fast.
