Part B: Calculate the missing check digit in ISBN An International Standard Book Number (ISBN) is a unique number assigned to each book. ISBN-13 has thirteen digits in 5 parts, in which the last digit is the "check digit". The check digit is base ten, and can be 0-9. To compute a missing check digit, each digit, from left to right, is alternatively multiplied by 1 or 3. Then, the sum of these products should be divided by 10 to find the remainder ranging from 0 to 9. Finally, the check digit can be found by subtracting the remainder from 10, that leaves a result from 1 to 10. For example, take the ISBN 978-0-306-40615-? : a) First calculate sum of products: 9x1 +7x3+8x1+0x3+3x1 +0x3+6×1+4×3 +0x1+ 6x3+ 1x1 + 5×3 = 93 b) Remainder upon dividing by 10 is 3. c) Remainder is subtracted from 10. d) Check digit is 7 (10-3).

However, you are allowed to call the scanf(...) function only once. Hint: To read single digits, we'll use scanf with the %ld conversion specification. The number that comes before "d" in the conversion specifier indicates the length of the integer that scanf actually reads from the input. Sample input: Enter the first twelve digits of ISBN-13: 978030640615 Sample output: Check digit: 7 Group Publisher Check digit Title ISBN 817525766-0 788175 257665 Group Title Publisher Check digit
