CHAPTER 2 CONSTRUCTS OF C LANGUAGE
2.3 Identifiers
An identifier is the name given to a variable such as:
Function
Object
Tag of structure, union, or enumeration type
Member of structure, union, or enumeration type
typedef name
Label name
Macro name
Macro parameter
Each identifier can consist of uppercase letters, lowercase letters, numeric characters, and the underscores. The
following characters can be used as identifiers.
There is no restriction for the maximum length of the identifier. In this compiler, however, only the first 249
characters can be identified (refer to Table 1-1 Maximum Performance Characteristics of this C Compiler).
_(underscore)
abcdefghijklm
n opq r s t u v w x y z
A BCD E F G H I J K L M
N OPQ R S T U V W X Y Z
0 123 4 5 6 7 8 9
All identifiers must begin with other than a numerical character (namely, a letter or an underscore) and must not be
the same as any keyword.
