fastest wc program

Write the fastest program that counts the number of words and lines in a string.

Here's my solution

#include "stdlib.h"
#include "stdbool.h"
#include "stdio.h"

// macro that increments index, sets variables for the next stage, and
// gotos the label indexed by the current character
#define next(c, lc, iw) cnt = (c); lcnt = (lc); in_word = (iw); idx++; goto *(jmp_arr[(int)str[idx-1]]);

                             
int main(int argc, char** argv)
{
  /* test string */
  char* str = argv[1];
 
 
  /* normally this would be done as a sort of partial evaluation, but i can't for example generate an optimized function at runtime in C */
  void** jmp_arr;
 
  jmp_arr = malloc(sizeof(char)*256);
  int i;
  for (i = 0; i < 256; i++)
    {
      switch ((char)i)
        {
        case '\n':
          jmp_arr[i] = &&newline;
          break;
        case ' ':
          jmp_arr[i] = &&whitespace;
          break;
        default:
          jmp_arr[i] = &&character;
          break;
        }
    }
 
  // null character points to exit label
  jmp_arr[0] = &&terminate;

 
 
  int cnt = 0;
  int lcnt = 1;
  bool in_word = false;
  int idx = 0;
 
 // jump to label for first char
  goto *(jmp_arr[(int)str[0]]);
 
 terminate:
  printf("words: %i, lines: %i\n", cnt, lcnt);
  return 0;
 
 whitespace:
  next(cnt, lcnt, false);
   
 newline:
  next(cnt, lcnt+1, false);
 
 character:
  if (in_word)
    {
      next(cnt, lcnt, true);
    }
  else
    {
      next(cnt+1, lcnt, true);
    }
}

Your implementations are horrible.

your code is shit, slow and doesn't work (it doesnt count anything lel)

minor update:replaced divide by shift, couple cycles saved.
http://pastebin.com/DqAwmPPL

About 7.2million cycles for 425kb file. >>42 can you write any version that is faster?

awk '{w += NF} END {print NR, w}' anus.txt

http://pastebin.com/NKne6UPZ v1.03 now at 7million cycles.

>>46
Your brilliance hasn't diminished one bit, frozen voidy.

Back to the imageboards, ``please''

[ocde]c=getfile(argv[1],&fsize);[/code]
You are an idiot.

Write the fastest program that counts the number of words and lines in a string.
You say "in a string" but not where it comes from, so you get just a function.

void countwl(unsigned char *s, unsigned int *pWords, unsigned int *pLines) {
 unsigned char c, *t = s, frist = *s, prevs = 1;
 unsigned int words = 0, lines = 0;
 while(c=*t++) {
  unsigned int n = !(c - '\n');
  unsigned int w = n || !(c - ' ') || !(c - '\t');
  lines += n;
  words += prevs & !w;
  prevs = w;
 }
 lines += !!frist;
 *pLines = lines;
 *pWords = words;
}

>>50
you forgot vertical tabs

Due popular demand countwords and countlines added to void.h

FrozenVoid and Couldder interacting in a thread, all we need now is tdavis to stop making those "NEXT" threads and join in this one.

http://pastebin.com/Ja3RQ2rD void.h 1.47 now includes countnonspaceseq which returns number of "words"(sequences) which can contain any character which isn't defined as C whitespace.

>>51
I can't say I've ever actually seen a text file with those in it.

http://pastebin.com/q1Dm2PBL v1.48 added generic countcharseq which can use a custom ascii table.

fuck you frozen void.

>>57
Lets rewrite it in Python so it will become beautiful.

>>57
AFAIK FV considered unions and structs a form of OOP and refused to use them.

>>58

python is more shit lol

I suggest to leave here.

OP's code is not even C.

But >>61 is the ironic shitposter, and >>57 is the actual shitposter!

>>64

People consider C to be a portable Assembler.  I consider them wrong because all CPU support a computed jump.

  void** jmp_arr;
 
  jmp_arr = malloc(sizeof(char)*256);
>implying void** and char are the same size
I shiggy diggy.

They are both shitposters.

>>56
that's fucking disgusting dude

>>67
You mean void* and char?

>>57,72
so this is the reaction of the new /g/ posters to frozenvoid.

>>74
Nice try kid but Frozenvoid is a newfag compared to me.
