Dates are commonly printed in several different formats in business correspondence. Two of the more common formats are: 25/10/2018 (and) October 25, 2018 Write a program that reads a date in the first format and prints it in the second format. Make sure the date entered -is valid.- Note: Make sure your program takes into consideration the possibility that the user may enter any character instead of '/' when entering the date.
