    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.

    Pay me!

    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.
