Yep, it's a Fizzbuzz.

Name: Anonymous 2012-03-13 8:32

more like
int main(frozenvoid) {

amirite? xD

Name: Anonymous 2012-03-13 9:46

printf(s[(!(i%3))|((!(i%5))<<1)], i);

It's like Lisp and C++ had a retarded baby!

Name: Anonymous 2012-03-13 10:18

Yep, it's an undefined behaviour.

OMG OPTIMIZED

#include <stdio.h>
char *s[] = {"%d\n", "fizz\n", "buzz\n", "fizzbuzz\n"};
int main(int i) {(i<101)?(printf(s[(!(i%3))|((!(i%5))<<1)], i),main(i+1)):0;}

Yep it's a perfect copy of the original post, but merely stripped of any already nonexistant readability.

Congratulations.

If it ain't fizzin', it's buzzin'.

Time for some benchmarks.

- GCC 4.6.3 -march=native -mtune=native -O3
- glibc 2.15
- Linux 3.2.9 SMP PREEMPT
- i5 2500K clocked at 3.30GHz
- stdout is /dev/null
- 50000000 iterations
- Programs are run two times and the best result is used.

Calling printf with the wrong number of parameters might be undefined behaviour.

Name: 11 2012-03-13 13:29

Actually the norm says it is perfectly safe to pass more arguments than described in the format string.

No, extra parameters to printf are ignored, ``faggot''. Try again.

can you test this too

#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;  
}

actually we pretty much did the same thing.

That's even better. It seems the <15times iteration at the end is actually a time eater!

BogoBuzz

Randomly generate a list of 100 elements, each element containing either: an int 1-100, "fizz", "buzz" or "fizzbuzz".
Check if the result is correct.
If correct, print out result. If not, start over.

So are you retards really timing I/O? Why don't you just allocate a single huge buffer and then write the entire thing to stdout at the end? It will be a lot faster and then you can jerk off since your implementation defined behavior is faster than someone else's.

now all I need is a quantum computer
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#define N 5

char *s[] = {"%d\n", "fizz\n", "buzz\n", "fizzbuzz\n"};

void randomfizzbuzzgenerator(char *c, int n){
  int i;
  for(i=1; i<=n; i++)
    c += sprintf(c, s[rand()&3], rand()%n+1);
}
   
void realfizzbuzzgenerator(char *c, int n){
  int i;
  for(i=1; i<=n; i++)
    c += sprintf(c, s[(!(i%3))|((!(i%5))<<1)], i);
 
}

int main(){
  int i;
  char buff[9*N+1];
  char result[9*N+1];
  srand(time(0));
 
  realfizzbuzzgenerator(result, N);
  while(1){
    randomfizzbuzzgenerator(buff, N);
    if(!strcmp(buff, result)) break;
  }
   
  printf("%s", buff);
   
  return 0;
}

umad because your implementation is slower
