Infinite loops

while(1){} vs. for(;;)

you forgot to mention do{}while(1);

take a look at the code your compiler produces for each one. a good
optimizing compiler should make them all the same, but not all compilers are
good optimizing compilers. i fell into the habit of using while(1) on
68000s; when i started working on 80x86s i found that for(;;) was faster.
i have therefore put

#if defined(MPU68000)
#   define loop while(1)
#elif defined(MPU8086) || defined(MPU80286)
#   define loop for(;;)
#endif

into my personal header. if do{}while(1) proved faster then I suppose I
would have to put an endloop in.

My favorites are

#define the_sky_is_blue 1
while(the_sky_is_blue){}

and

#define ever_and_a_day ;;
for(ever_and_a_day){}

or, in Pascal

CONST Hell_freezes_over = TRUE;
REPEAT ... UNTIL Hell_freezes_over;

But my boss gets angry enough at me as it is! (are you there, Gary?)
