I sure as hell hope this is on the test.

#include <stdio.h>

int main()
{
     /* Declare variable */
     float beers ;
     for (beers = 100; beers != 0; beers -= 1)
     {
          printf("%f %s\n %f %s\n",
               beers, "bottles of beer on the wall",
               beers, "bottles of beer",);
          printf("Take one down, pass it around\n");
          printf("%e bottles of beer on the wall\n\n", beers - 1 );
     }

     return
}
