/* Learning to program in C ... first day's illustrations

Shows a practical little program in C with keyoard input, variables,
calculations, conditionals, a loop, and screen output. As with any
illustrative program, there are things in here that provide a
demonstration in a way I wouldn't in a real application intended for
use, such as some of the line splitting, constant use, lack of use of
character strings ... some features included just to show them, others
excluded because they come later on the course */
