    Check certain positions of an int?

    This is possibly a very basic question, but how to check the second or third value of of an int variable? Am I supposed to use on of them string functions or is there a simpler way?

    What do you mean by sting functions on an int ?
    Also, yes getting the third or fourth position is as simple as reaching the third or fourth digit which you should know how to do from math class.

    I am trying to write a function that checks certain positions of an int and the value of it. I would like to know how to do this. And what do you mean with math class?

    What I meant was that there is a simple formula to get each digit of an int. Think about it, its pretty easy actually.

    Supposing your number was 100
    then the hundredths place digit is 1
    and the tenths place digit is 0
    and the digit at the ones place is 0

    Now how would you write a program to do that ?
