There are some conventions that I use consistently to help you identify various parts of the text—be they code samples or a kind of enigmatic shorthand for indicating how a piece of code is supposed to be used. This stems from the fact that you need to know:
Syntax: How the code is to be used.
Semantics: Where the code is to be used.
In other words, I’ll provide a kind of generic template description that shows you how to write the single piece of code, as well as showing you how it is used alongside other bits and pieces of programming. Each important facet of C code will be presented in this way.
To distinguish something that you should type in and be used as code, we use a specific font. Whenever text is shown ...
