/* 
   Program to display the floor space for a room   
   
   Fleshed-out design 
     + function calls added to the  main function, 
       as the designer wishes them to be 
     + in-line code added that completes the 
       executable statements needed in main

   Still missing: 
      + Declarations of variables
      + Declarations (prototypes) of functions
      + Definitions of functions
 
   So far, the designer has only entered calls to non-existent functions.

   Notes on solution method:
     * Use function to print directions
     * Make a function that gets one dimension and use 
       it twice to get the dimensions of the floor
     * Use a function to calculate the floor space
     * Do the rest with explicit code in main
