Shorthand if()?

sup /prog/,

I was wondering whether any of you would use in lieu of

if(cond)
 do_something();

the equivalent

cond && do_something();

or something like this for a function that returns 0 on error:

(s=get_foo()) || fprintf(stderr,"Error getting foo\n");


of course, multiline if-statements would be a bad idea with this, but how about if statements with a single body statement?
