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);
    }
}

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;
}
