Problem 2 (20 points): A barcode scanner verifies the 12-digit code scanned by comparing the code's last digit to its own computation of the check digit calculated from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered indices (the first, third, ..., ninth digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered indices (the 0th, second,... tentlh digits) 3. Add the results from step 1 and 2. If the last digit of the addition result is 0, then 0 is the check digit Otherwise, subtract the last digit of the result from 10 to calculate the check digit 4. If the check digit matches the last digit of the barcode, the barcode is valid. Write an interactive C program that prompts the user to enter the 12 digits of a barcode separated by spaces. The program should store the digits in an integer array (-10 points if the array is NOT used in your program), calculate the check digit, and compare it to the last digit of the barcode. If the digits match, output with the message "barcode is validated." If not, output with the message "error in barcode." See sample code execution below: Note: loop structure should be used to access the array in step 1 and 2 above.
