Hi,

I am doing exercise 1-21 Pg 48 The C programming language" (Kernighan
& Ritchie). Since I am finding difficulty inspecting tabs in XFCE4.10
terminal, I would like someone to inspect this program which replaces
repeating spaces with tabs when there are sufficient consecutive
spaces. I am not asking for a long reply. A short reply giving me
feedback as to whether the code is good or not, is enough.

exercise 1-21
-------------------------------

#include <stdio.h>

/* insert tabs instead of repeated spaces */

int tab_width = 3;

void replace_spaces_with_tabs(char c) {
  int count = 0;
  if (c == ' ') {
    ++count;

    while((c = getchar()) == ' ') {
      ++count;
      if (count == tab_width) {
        putchar('\t');
        count = 0;
      }

      if (count < tab_width && count > 0)
        while(putchar(' ') && --count);
    }
  } else putchar(c);
}

int main() {
  char c;
  while((c = getchar()) != EOF) {
    replace_spaces_with_tabs(c);
  } else putchar(c);

return 0;
}

--------------------------------------
