• This creates user-defined type Months with enumera%on
constants represen%ng the months of the year.
• The first value in the preceding enumeration is explicitly set
to 1, so the remaining values increment from 1, resul%ng in
the values 1 through 12.
• Any enumeration constant can be assigned an integer value
in the enumeration definition, and subsequent
enumeration constants each have a value 1 higher than the
preceding constant in the list un%l the next explicit se^ng.
