Program Notes

Because the const array object Snames is declared above all the functions, it can be used in any of the following function definitions. Like the const Seasons, Snames is shared by the whole source code file. The program doesn’t have a using directive, so array and string have to be used with the str:: qualifier. To keep the program short and focused on how functions can use objects, the fill() function doesn’t check for valid input.

Both fill() and show() have drawbacks.
