  SOCIAL INSDURANCE NUMBER VALIDATION PROGRAM
  ___________________________________________
  
  Write a 'C' program to validate the accuracy of any Social
  Insurance Number (SIN). ( or to impress others by guessing the
  last digit, given the first eight digits ).
  
  The Social Insurance Number contains nine digits. ( the first
  eight digits are assigned, while the ninth is constructed from
  the first eight, and therefore acts as a check-digit).
  
  Ex: SIN =  1    9    3    4    5    6    7    8    7
  1st  2nd  3rd  4th  5th  6th  7th  8th  check-digit
  
  Steps: ( High Level Specifications ).
  ______________________________
  
  (1) Construct a 4 digit number from the 2nd, 4th, 6th and 8th
  digit of the SIN.         ie. 9 4 6 8
  
  (2) Multiply the constructed digit in step (1) by two.
  ie. 9 4 6 8   *  2  = 1 8 9 3 6
  
  (3) Cross add all the resulting digits of step (2).
  ie. 1+8+9+3+6   = 27
  
  (4) Construct a 4 digit number from the 1st, 3rd, 5th and 7th
  digit of the SIN          ie. 1 3 5 7
  
  (5) Cross add all the resulting digits  of step (4).
  ie. 1+3+5+7 = 16
  
  (6) Add the results of step (3) and (5) together.
  ie. 27 + 16 = 43
  
  (7) If the result of step (6) is a multiple of 10 then
  the check digit is 0
  Otherwise the check is 10 - MOD(results of step (6) , 10 )
  ie. 10 - MOD(43,10) = 7
  
  Test you program on the following SIN numbers:
  
  111111111
  222222222
  333333333
  444444444
  555555555
  666666666
  777777777
  888888888
  999999999
  205446651
  193456787
  3 more numbers (be creative)...
  
  Requirements:
  
  1) use of array(s).
  2) use of loop(s).
  3) nicely formatted output, with message and correct check digit, as
  below.

  999999999        Wrong SIN            8
  205446651        Correct SIN          1
  193456787        Correct SIN          7

  your program should prompt the user for a Social Insurance Number,
  validate it, and print the Message as above, with the Correct
  Check-Digit.
  
  You may need to convert the characters enterd by the user, into
  integer using the "atoi" function.
  
  Your program should loop until the user enters a special character
  as a social insurance number.
  
  NOTE: We assume that if the Check-Digit is correct, then the SIN is
  a valid number.
