Im horrible at this stuff, and my latest class assignment really hurts my head...

If anyone can help or give me some ideas...

Problem:

Determine the following info about each value in a list of positive integers.

a. Is the value multiple of 7,11, or 13?

b. Is the sum of the digits odd or even?

c. is the value a prime number?

Write a function with three type int output parameters that send back the answers to these three questions.

I'm suppose to use pointers too...

I'm pretty lost, and dont really have much of a start.

Can someone guide me in a general direction?
