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.

Good luck.

Pay me!
gcount Get number of characters extracted by last unformatted input operation (public member function)
You should study up on c and C++. Hope you were not talking about sizeof(int). Well here's a link that may help solve your vague question.

BTW, possible buffer overflow! Think about it.
