Padding numbers

Hello Everyone. I was wondering what function I could use to pad some
input. For example, I have something like: cin >>
memory[OperationCode]; If the user enters less than 4 digits ie. '3', I
would like to add 3 zeros to the beginning of the number ie. '0003'.

I could use some if/else statements to get the size of the input...like
if(memory[OperationCode] < 10){
   cout << "000" << memory[OperationCode];
etc...

But I was hoping for a shorter way...Any Ideas?
Thanks.
