How can mixed data types (int, float, char, etc) be stored in an array?
... the iPhone 5S. In iOS 7, virtual addresses are 33 bits (byte-aligned), so word-aligned addresses only use 30 bits (3 least significant bits are 0), leaving 34 bits for tags. Objective-C class pointers are word-aligned, and the tag fields are used for many purposes, such as storing a reference count...
