Programming in C: Remember these points on Variables.

Don’t begin variable names with underscore, since library routines often use such names. Upper and lower case letters are distinct. Atleast first 31 characters of an internal name are significant. External names may be used by assemblers and loaders over which the language has no control. The definition of C gurantees that any character in the machine’s standard printing character set will never be negative.
