Help in C with integers

Question

You need to use division and remainder by 10. Consider this example:

• 163 divided by 10 is 16, remainder 3
• 16 divided by 10 is 1, remainder 6
• 1 divided by 10 is 0, remainder 1

You'll notice the remainder is always the last digit of the number that's being divided. How do I do this in C?

Answer 1

Use the Modulus operator:

 remainder = 163 % 10; // remainder is 3

It works for any number too:

  remainder = 17 % 8;  // remainder is 1, since 8*2=16

(This works for both C and C#)

Answer 2

With the modulus operator (%):

15 % 12 == 3
17 % 8 == 1

Answer 3

It looks like homework so I won't give you code, but I suggest you research the modulo operator and how this could be used to solve your assignment.
