Question 8
For the given subquestions, consider a function called NextDate which takes as input a valid date in mm/dd/yyyy (month followed by date followed by year) format and computes the date of the next day. For example, given 06/14/1996, the NextDate function will return 06/15/1996> and when given 02/28/2019>, the NextDate function will return 03/01/2019.
