The scanf format string for ans is "%d". That puts an integer value in ans. However, the user entered 'a', 'b', or 'c'. None of these are valid integer values, so the format string is not satisfied and ans is not changed. Refer to the manpage for scanf. You want the format specifier for characters ("%c"). Notice that the type of the "%c" argument should be char*, not int*.

By the way, perhaps you want the answers to be case insensitive (either 'a' or 'A' are correct answers) so the student isn't penalized if caps lock is on. Refer to tolower.
