When implementing an infinite loop, is there a difference in using while(1) vs for(;;) vs goto (in C)?

Question

When implementing an infinite loop, is there a difference in using while(1) vs for(;;) vs goto?

Thanks, Chenz

Answer 1

There is hardly any difference in generated assembly. It's more of an stylistic issue:

Goto - just ooogly: jumps backward, no explicit infinite block

while(1) - better, requires "dummy" condition though and you'll be often warned by compiler(warning level 4) or static analysis tool

for(;;) might not be the prettiest, but imho fits best because this construct cannot have any other meaning (compared to while). But some other people prefer while(1) for the "same" reason...
