Supported Data Types and Variables
overflow. The suffix l or L may be used with the constant to indicate that it must be assigned either
a signed long or unsigned long type, and the suffix u or U may be used with the constant
to indicate that it must be assigned an unsigned type, and both l or L and u or U may be used to
indicate unsigned long int type.
float constant. The suffixes l or L specify a long double type which is considered an identical
type to 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.

Any integral constant will have a type which is the smallest type that can hold the value without
Floating-point constants have double type unless suffixed by f or F, in which case it is a

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
