Supported Data Types and Variables
double by HI-TECH C.
constant has char type. Multi-byte character constants are not supported.
world". The type of string constants is const char * and the strings are stored in the program
memory. Assigning a string constant to a non-const char pointer will generate a warning from the
compiler. For example:
Defining and initializing a non-const array (i.e. not a pointer definition) with a string, for example:
produces an array in data space which is initialised at startup with the string "two" (copied from
program space), whereas a constant string used in other contexts represents an unnamed const-
qualified array, accessed directly in program space.
sequences, except where the strings are used to initialise an array residing in the data space as shown
in the last statement in the previous example.
by the compiler. Thus:
assigned the pointer with the string "hello world".
3.4.2 Bit Data Types and Variables
HI-TECH PICC STDsupports bit integral types which can hold the values 0 or 1. Single bit vari-
ables may be declared using the keyword bit. bit objects declared within a function, for example:
42
Character constants are enclosed by single quote characters ’, for example ’a’. A character
String constants or string literals are enclosed by double quote characters ", for example "hello
HI-TECH C will use the same storage location and label for strings that have identical character
Two adjacent string constants (i.e. two strings separated only by white space) are concatenated
