A character string is actually a static array of characters, where the array has
been initialized with the given characters and a terminating null character.
Character strings cannot be modified during program execution; the static array
containing the characters resides in the program text section, which is typically
loaded into Read-Only Memory (ROM).
A newline is illegal inside of a character string. There are two ways, however, to
continue a character string on a new line. A character string may be continued by
placing a backslash (\) immediately before the newline. For example, the
following two strings are equivalent:
"this is a test of a string that \
spans two lines"
"this is a test of a string that spans two lines"
Character strings can also be continued by placing them adjacent to each other.
For example, the following two strings are equivalent:
"this" " string " "has "
"been broken"" into several pieces"
"this string has been broken into several pieces"
Escape sequences are converted into single characters before adjacent
character strings are concatenated. For example, the first string below is
equivalent to the second string, not the third:
"\x12" "3"
"\x0123" (two characters)
"\x123" (one character)
The maximum length of a character string is 512 characters unless it is increased
with the
-XC
flag. When two or more strings are concatenated, the character
length limit applies to the combined length.
2.9. Types and Representations
This section describes the internal representations of the various integer and
floating-point types. It also describes the correct usage of enumeration types and
bit fields, and discusses the issues concerning the
const
,
volatile
, and
void
type
specifiers.
