Ooops, this is the corrected program for exercise1-21 #include <stdio.h>
/* insert tabs instead of repeated spaces * I am assuming a tab is equivalent to 3 spaces and forgetting tabs that are defined at specific columns */ 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; } else continue; if (count < tab_width && count > 0) while(putchar(' ') && --count); } } putchar(c); } int main() { char c; while((c = getchar()) != EOF) { replace_spaces_with_tabs(c); } return 0; } On 23/06/2016, Edward Bartolo <edb...@gmail.com> wrote: > Hi, > > I am doing exercise 1-21 Pg 48 The C programming language" (Kernighan > & Ritchie).
