Chapter 8, Problem 8.14E

(Tokenizing Telephone Numbers) Write a program that inputs a telephone number as a string in the form (555) 555-5555. The program should use function strtok to extract the area code as a token, the first three digits of the phone number as a token and the last four digits of the phone number as a token. The seven digits of the phone number should be concatenated into one string. The program should convert the area-code string to int and convert the phone number string to long. Both the area code and the phone number should be printed.
