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;
}
