C Program

An integer n is divisible by 9 if the sum of its digits is divisible by 9. Develop a function to display each digit, starting with the rightmost digit. Your program should also determine whether or not the number is divisible by 9. Write a function that calculates the sum of the digits in an int, checks to see if the sum is evenly divisible by 9 and returns 1 for yes and 0 for no. Hint: Use the % and 10 operator to get the least significant digit and use / and 10 to remove the least significant digit. Please use a for-loop, declare variables and only use the library.
