If it allows you to use ints... it is pretty simple to do...

int deletefirst(int n)
{ 
         int temp;
         if (n<10) return 0; // delete the first digit
         else 
         {
                  temp=n%10;// save the last digit
                  n=n/10;//changes n
                  return delete(n)*10+temp;// goes until n<10 and then rebuilds the number
          }
}
