Why use infinite loops?

Question

Another poster asked about preferred syntax for infinite loops.

A follow-up question: Why do you use infinite loops in your code? I typically see a construct like

Answer 1

I would consider using an infinite loop to program the guidance system of a missile.

while ( true ) { go2Target ( ) ; }

From the perspective of the missile's guidance computer, the loop once started does repeat until the end of time.

Perhaps a purists would favor

while ( ! blown2Bits ( ) ) { go2Target ( ) ; }

but then how do you implement the blow2Bits method? what would it mean if blow2Bits returned true?
