integer for a year and returns true if the year is a leap year and

false otherwise. Define a function $-$ ValidDate$()-$ that takes a

Date argument and returns true if it's a valid date or false if it

initialized to the names of the $12$ months of the year: "January",

"February", $...$ read a date from the user and store it in the date

$15,2021$ format, using the array of months.Ex: If input: $"3/15/2021$"Returns: "You entered March $15,2021"$
