/*  Random Phone Numbers (10 points)

Write a complete C program that generates 10 random phone 
numbers and prints them on the screen. The numbers must be
formatted as shown in the example given below. The 10 numbers
must be different every time your program is called. The program
is not required to check if these are valid phone numbers (e.g.,
some of them may start with a zero or the area code may be invalid).

SAMPLE RUN:
	
(142)-677-8454
(445)-443-5049
(280)-766-7669
(776)-046-4139
(432)-903-8187
(901)-893-4787
(067)-439-5665
(107)-037-6924
(775)-917-8436
