Answer / venkata mahesh
We can define constants of any type by using the #define
compiler directive. Its syntax is simple--for instance
#define ANGLE_MIN 0
#define ANGLE_MAX 360
would define ANGLE_MIN and ANGLE_MAX to the values 0 and
360, respectively. C distinguishes between lowercase and
uppercase letters in variable names. It is customary to use
capital letters in defining global constants.
