Answer 2

I'll give you a rough sketch.

Seperating the last digit from the others is as easy as dividing by 10:

int a = 1234;
int division = a / 10; // 123
int remainder = a % 10; // 4

You'll also need a total which will store the result. It starts out as 0, and during each iteration you do:

total = total * 10 + remainder;

And that's it. You do that in a loop until you've consumed all the digits. Try printing out the division, remainder, and total at each step so you get a feel for what's going on.
