Elements of C
This chapter describes the elements of the C programming language, including the names, numbers, and characters used to construct a C program. The ANSI C syntax labels these components “tokens.” This chapter explains how to define tokens and how the compiler evaluates them.
The following topics are discussed:
The chapter also includes reference tables for trigraphs, floating-point constants, integer constants, and escape sequences.
“Operators” are symbols (both single characters and character combinations) that specify how values are to be manipulated. Each symbol is interpreted as a single unit, called a token. For more information, see Operators in Chapter 4.
