Another thing I do to make code compact is to omit the braces if the

accounted for with braces.  For instance:
 
    for(i = 0; i < 10; i++) {
printf("%d\n", i);
if((i % 2) == 0)        /* Omitted braces */
    printf("The preceding number is even.\n");

I tend to use the braces for ifs out of self defense. I've been burned a
couple of times with stuff like

if (foo == bar)
    exit(-1);

and at some later time deciding some logging would be nice.

if (foo == bar)
    log("something went off the rails!):
    exit(-1);

I also do things like test the return of malloc(). I know if malloc()
returns NULL I probably have a snowball's chance of logging or doing
anything graceful but it's worth a try.
