// I have trouble getting q in this code example can you please explain how can I find it? When I compiled it I got p but it gives me an error when finding q. I have in this case an example that gives me 15 as p, but I have trouble comparing 15 with 51 to figure if it is the exact number. So the main question is how can I get the inverse digits of 15(that is 51) from the code. thanks

/*

This program determines whether the value of the global variable x (expressed in hexadecimal notation) is a 16-Harshad number and if so, whether the factors involved are mirrors of each other. That is, if x = p * q, where p = sum of hexadecimal digits of x and q is the reverse of p (same digits in reverse order). For example, 6A5 = 15*51 in base 16.

The program prints a statement indicating which of 3 cases is true: 1) x is not a 16-Harshad number, 2) x is a 16-Harshad number without mirror factors (and gives the factors), or 3) x is a 16-Harshad number with mirror factors (and gives the factors).
