Selecting certain part on an entry.

[Inori]

Hello!
I'm really new to C++ and I want to write a simple program, that would proccess entered number part by part, but I can't figure out (nor could I find anything on the subject) how to make my program do it.

For example, it should look like this:

Enter code: 32101243421
if <first two digits> < xx, then xx
if <third and fift digit> > xx, then xx
if <sum of all digits> > xx, then xx.
etc.

Thanks in advance.

Off the top of my head, I'd suggest reading about the modulo operator which is useful for getting the value of each digit. To shift a decimal number 1 digit to the right simply divide by 10.

int number(121123);
int nextDigit(0);

nextDigit = number % 10;  // nextDigit becomes 3
number /= 10;  // number becomes 12112

You can play around with some loops to figure out each digit and sum them as you go. You could build an array of digits in a loop and then use the array to accomplish all of the other requirements. Good luck!
