Greetz Riot. :)
haven't properly checked but hopefully i've dug up a fairly useful url for you to take a gander at. ;)
http://oopweb.com/CPP/Documents/Thin...ume/chap07.htm
definitely a good link but not exactly what i was looking for what i mean was if i have something like:
int numbers;
cout << " Enter some number: ";
cin >> number;
I want to find out how many characters are being held in the var numbers.
This thread is a month old. But better late than never.
Ok. I found this site interesting. It might help with your question. Here is the link:

BTW, possible buffer overflow! Think about it.
