Using C programing
An integer n is divisible by 9 if the sum of its digits is divisible by 9. Develop a program that uses this method to determine whether or not a number is divisible by 9. Test it on the following numbers:
n = 154368
n = 621594
n = 123456
Use the % operator to get each digit; then use / to remove that digit. So 154368 % 10 gives 8 and 154368 / 10 gives 15436. The next digit extracted should be 6, then 3 and so on.
On the next page is a screen shot of a working solution with the loops missing. After you write your loops and get the program running, you can test it by hitting run, then hitting the halt button. Examine memory at PORT B to see if it worked. PORT B is at address 01 in the memory window.
