Enumerable Types
Types that consist of certain integral values and are carried by symbolic names
#define FALSE 0 #define TRUE 1 or: Enum definitions: enum bool {FALSE,TRUE}; /*bool optional*/ enum month {JAN=1,FEB=2,…,DEC=12}; enum colors {WHITE=1,BLACK,GREEN=8,RED}; /* month, colors optional */
Using enum types enum bool b[10]; enum bool cond = FALSE; Note: cond = 2; is legal but will crash!
enum vs. #define ( enum is superior) - compiler may check for type mismatch. - debugger may recognize the symbolic names.
