Fixed Number of digits

How would I output a fixed number of digits. I DO NOT mean a fixed number of digits after the decimal point. I mean a fixed number of digits ALWAYS no matter what my number turns out to be.

How can this be done in C# and in C if anyone knows.

Thanks!

4 digits regardless of the number?
int n = 34;
Console.WriteLine(n.ToString("0000");

This works if the number is less than 4 digits, now is the number is greater than 4 digits which ones are you going to get rid of?

you can always create a custom format here's and example:
