General C coding notes and Examples

DATA TYPES PICC standard
Type	Size	Range	Example
VOID	0 bits	None
SHORT INT1	1 bit	0,1
CHAR INT INT8	1 byte	0 to 255 0 to (2⁸ -1)
LONG INT16	2 bytes	0 to 65535 0 to (2¹⁶ -1)
INT32	4 bytes	0 to 4294967295 0 to (2³² -1)
FLOAT	4 bytes
STRUCT These follow the same rules for placement in and out of function blocks as the other variable types.	Variable	As built	//this defines the structure STRUCT box { char length; char width; char height; }; //this defines the structure and creates variable box3 STRUCT boxx { char length; char width; char height; } box3; //this defines the structure and creates/initializes box4 STRUCT boxxx { char length; char width; char height; } box4 = {1,2,3}; //this creates variable box1 as a "box" structure STRUCT box box1; //this creates and initializes box2 STRUCT box box2 = {1,2,3}; //this uses the variable box1.length = 1; box1.width = 2; box1.height = 3;
