It looks plain and correct to me :) An equivalent version which avoids
the chain of ifs might read:
------
#include <stdio.h>
int main (int argc, char *argv[]){
int c,d=0;
while((c=getchar()) != EOF){
putchar(c);
while(c == ' ' && (c=getchar()) != EOF ){
d=1;
}
if (d){
putchar(c);
}
d=0;
}
}
-----
which can be further streched into:
-----
#include <stdio.h>
int main (int argc, char *argv[]){
int c,d=0;
while((c=getchar()) != EOF){
c=putchar(c);
while(c == ' ' && (c=getchar()) != EOF && (d=1));
if (d && putchar(c) && (d=0));
}
}
-----
But, admittedly, sacrifying quite a lot in terms of readability
without a reason.
