Here is a C version of fizzbuzz if anyone has an interview tomorrow:

  #include <stdio.h>
  int main(void)
    {
      int i = 0;
      for(i=1; i<=100; i++)
      {
        unsigned int f = 0;
        if(i % 3 == 0)
        {
          f = 1;
        }
        if(i % 5 == 0)
        {
          f |= 2;
        }
        if(f == 0)
        {
         printf("%d\n",i);
        }
        else if(f == 1)
        {
          puts("fizz");
        }
        else if(f == 2)
        {
          puts("buzz");
        }
        else if(f == 3)
        {
          puts("fizzbuzz");
        }
      }
      return 0;
  }
