Question

In the United States, a Social Security number (SSN) is a nine-digit number that
is a national identification number for taxation purposes. Write a program that
asks the user for their social security number in DDDDDDDDD format (where
D is digit). The program first performs a basic check if the number corresponds
to actual SSN by making sure it has 9 characters in it. If yes, it creates a string
variable new ssn with SSN in user-friendly DDD − DD − DDDD format and
prints it. If not, it prints an error message Incorrect SSN length.
