I am writing a program to validate an isbn number. In my code I am instantiating an array of chars. Then I am trying to read in what the user types in (isbn number) and assign it to the array. I need to be able to maniupulate (add and multiply) some of the numbers in the isbn, but when I try to print out the first value in the array 'isbn' it gives me the ascii dec of the number, instead of the number itself. When testing this out so far, the isbn number I used starts with a '0' and when I printed it out, it printed out '48' instead of 9 (48 is the dec number on the asii table). I'm not really sure what that dec is anyway, so if someone could explain this and explain how to get the actual numbers from the isbn number instead of the dec value I would greatly appreciate it. Thank you.
