ever. (for any arbitery n)



#include <stdio.h>

 

#define N 100

 

int main(void) {

  char arr[] = "%d\n%d\nfizz\n%d\nbuzz\nfizz\n%d\n%d\nfizz\nbuzz\n%d\nfizz\n%d\n%d\nfizzbuzz\n";

  int news[]={0,3,6,11,14,19,24,27,30,35,40,43,48,51,54,63};

  int i=N/15, j=1;

 

  while(i--){

   printf(arr, j, j+1, j+3, j+6, j+7, j+10, j+12, j+13);

   j+=15;

  }

  arr[news[N%15]]='\0';

  printf(arr, j, j+1, j+3, j+6, j+7, j+10, j+12, j+13);

  

  return 0;    

}

Unnecessary arithmetic. Unnecesary branching. printf.
Not optimized at all.

#include <stdio.h>



#define FBSTR(a,b,c,d,e,f,g,h) #a "\n" #b "\nFizz\n" #c "\nBuzz\nFizz\n" #d   \

                               "\n" #e "\nFizz\nBuzz\n" #f "\nFizz\n" #g "\n" \

                               #h "\nFizzBuzz\n"

#define FBSTRA(a,b) FBSTR(a##1,a##2,a##4,a##7,a##8,b##1,b##3,b##4)

#define FBSTRB(a,b) FBSTR(a##6,a##7,a##9,b##2,b##3,b##6,b##8,b##9)

#define FBSTRAB(a,b,c) FBSTRA(a,b) FBSTRB(b,c)



int main(void)

 { write(0, FBSTRAB(,1,2) FBSTRAB(3,4,5) FBSTRAB(6,7,8) FBSTRA(9,), 413); }
