a own 4- [ 40p]A barcode Scanner for Universal Product Codes (UPCs) verifies the 12-digit code scanned by comparing the code's last digit (called check digit) computation of the check digit from the first 11 digits as follows: [step 1] Calculate the the digits in the odd-numbered positions (the first, third, eleventh digits) and multiply this sum by 3. sum II. (step 2] Calculate the Sum the digits in even-numbered positions second, fourth, tenth digits) and this to the previous result (result of stepl). III. (step 3]If the last digit of the result from step is 0, then 0 the check digit. Otherwise, subtract the last digit from 10 to calculate the check digit. IV. (step 4]If the check digit matches the final digit of the 12-digit UPC, the UPC is assumed correct. 1. 2. Write main function that prompts the user to enter the 12 digits of bar code. . The program should store the digits in an integer array. write check" function calculate the check digit, and compare it to the final barcode digit. If the digits match, output the barcode with the message Mvalidated. not, output barcode with the message "error in barcode. Also, output with labels the results from steps 1 and 2 of the check-digit calculations. Note that the first digit of the barcode will be stored in @lamento of the array. (clue : Mcheck" function ta kes two argument and it doesnt return any value)
