i need to add
bool containsDigit(int number, int digit);
to the working program and still get the same output.
how would that work?

That function should look at the digits of number and see if any of them are equal to digit.

what is the exact question. I am not sure what you are asking. Whether you need to know how to include this function and call this function from main?
