An ISBN (International Standard Book Number) is a 10 digit number that is used to identify a book. The first nine digits of the ISBN number are used to represent the Title, Publisher and Group of the book and the last digit is used for checking whether ISBN is correct or not. To uniquely identify a book a 10-digit ISBN number is used. The rightmost digit is checksum digit. This digit is determined from the other 9 digits using condition that 10d, + 9d, + 8d, +.+ dio must be a multiple of 11 (where d, denotes the i" digit from the right). The checksum digit d; can be any value from 0 to 10: the ISBN convention is to use the value X to denote 10. Write a C program using pointers that receives a 10- digit ISBN, and computes the checksum, and reports whether the ISBN number is correct or not. Example: 007462542X = 10°0 + 9*0 + 8*7 + 74 + 6*6 + 52 + 45 + 3"4 + 2"2 + 1 10 = 176 Since 176 leaves no remainder when divided by 11, hence it is a valid ISBN. Note: When the check digit turns out to be "10" an "X" is written in the ISBN check digit place ("X" is the Roman numeral for 10] so that there are exactly 10 symbols used in an ISBN.

![An ISBN (International Standard Book Number) is a 10 digit number that is used to identify a book. The first nine digits of the ISBN number are used to represent the Title, Publisher and Group of the book and the last digit is used for
checking whether ISBN is correct or not. To uniquely identify a book a 10-digit ISBN number is used. The rightmost digit is checksum digit. This digit is determined from the other 9 digits using condition that 10d, + 9dz + 8dg + + d4o
must be a multiple of 11 (where d, denotes the i" digit from the right). The checksum digit d; can be any value from 0 to 10: the ISBN convention is to use the value X to denote 10. Write a C program using pointers that receives a 10-
digit ISBN, and computes the checksum, and reports whether the ISBN number is correct or not.
Example: 007462542X = 10°0 + 9*0 + 8*7 + 74 + 6*6 + 5*2 + 4*5 + 3"4 + 2*2 + 110 = 176
