WebAdjacent bytes have addresses that differ by one. The macro NULL expands to the value 0. Casting between integers and pointers results in no change of representation. The compiler warns of casts between pointers to functions and pointers to data. The type size_t is defined as unsigned int. The type ptrdiff_t is defined as signed int.

Webconstants can be freely mixed. In the following example, list1 and list2 have the same contents: list1 BYTE 10, 32, 41h, 00100010b list2 BYTE 0Ah, 20h, 'A', 22h Defining Strings To define a string of characters, enclose them in single or double quotation marks. The most common type of string ends with a null byte (containing 0). WebThis yields results you may not expect; for example, size of (int) == 1 (not 2). It should also be noted that contrary to common usage, a byte is not defined as 8 bits. A byte is defined as the unit of data capable of holding a single character on any given machine. Hence, if the term "byte" is used on C2000 it refers to 16 bits.
