|Use symbolic names for
||In general all numeric constants should be defined
symbolic names either through C's preprocessor's #define or with a const
|Put digits on both sides of a
floating point value
||Floating point literals should include digits on both
sides of the decimal point.

use capitals "A" through "F" and small "x"
||Hexadecimal numbers should always have the

|Long word constants should
use capital "L" suffix
||Long int numbers should be followed by an uppercase
"L" since a lowercase "l" could be confused with the number one
