This chapter describes features of the Objective-C language that you don’t necessarily need to know to write Objective-C programs. In fact, most of these come from the underlying C programming language. Features such as functions, structures, pointers, unions, and arrays are best learned on a need-to-know basis. Because C is a procedural language, some of these features go against the grain of object-oriented programming. They can also interfere with some of the strategies implemented by the Foundation framework, such as the memory allocation methodology or work with character strings containing multibyte characters.

Note

There are ways to work with multibyte characters at the C level, but Foundation provides ...
