while (1) Vs. for (;;) Is there a speed difference?

Hi,

Which is better,faster and more optimized way to implement infinite loop - for(;;) or while(1)? and why?

Answer 1

I prefer for(;;) because it doesn't test anything and semantically this is what you mean. It doesn't make so much sense to keep testing if 1 is true. However any professional C programmer should immediately recognize both idioms as both are used.

In terms of actual performance there should be no difference. The compiler will optimize away the test.

I tried testing both to see which is faster but neither of them has completed yet.
