Am I the only one who, in response to: "dont use loops" thought of the following:

   int numDigits(int num){
     if (num < 0){
       return numDigits(-1 * num);
     }
     if (num < 10){
       return 1;
     }
     if (num < 100){
       return 2;
     }
     if (num < 1000){
       return 3;
     }
     if (num < 10000){
       return 4;
     }
     if (num < 100000){
       return 5;
     }
     if (num < 1000000){
       return 6;
     }
     if (num < 10000000){
       return 7;
     }
     if (num < 100000000){
       return 8;
     }
     if (num < 1000000000){
       return 9;
     }
     return 10; // cant be more than 10 since sizeof(int) == 4, otherwise extend to 19
   }

The statements will duck type to numbers so you could just be really silly and do something like:

   return 1 + (n >= 10) + (n >= 100) + (n >= 1e3) + (n >= 1e4) + (n >= 1e5) + (n >= 1e6) + (n >= 1e7) + (n >= 1e8) + (n >= 1e9) ...
