Int Length

[G854izwU]

Hey guys I was just wondering what you guys think the best way to find the length of an int is. I worked out a nice and easy way to do it my way is shown below. If you guys have your own ways or a better way tell me about it I want to see how well I'm doing in learning C++. Thanks

int findIntLength(long long number) {

    int digits = 0;
    long long tens = 1;

    while (number >= tens) {

        tens *= 10;
        digits++;

    }

    return (digits);

}

I don't understand how to use that one... I put it in a program but when I fed it a 3 digit number it spit out 49. I'm not sure where it got that =P but mine works better in my opinion.
