 To understand what _better code_ is we first need to understand what _good code_ is. Students are often taught that good code is code that does what the specification says it should. But such an answer begs the question of what is a good specification? Nearly every experienced developer I've met has a snippet of code filed away that has profound beauty - it likely has no corresponding specification and may not even contain a single comment. So what is good code?

-The notion of a _type_ is a fundemantal component of programming. Types are created to represent a class of objects. Types can be very general, such as “integer” or very specific such as “index into the collection of documents.”

 Object-oriented programming has been one of the paradigms supported by C++ from its invention. The idea of type inheritance and virtual functions were borrowed from Simula[^cpp-history]. Inheritance can represent a subtype or protocol relationship. Although the two are closely related, in this chapter we're primarily concerned with subtype relationships through class inheritance. Protocols are discussed in the next chapter. {::comment}link{:/comment}
