Infinite loops - top or bottom? [closed]

Question

In the spirit of questions like Do your loops test at the top or bottom?:

Which style do you use for an infinite loop, and why?

• while (true) { }
• do { } while (true);
• for (;;) { }
• label: ... goto label;

Answer 1

while(1)
{
//do it 
}

That's how I roll.

Answer 2

I prefer while(1) or while(true) -- it's the clearest. do { } while(true) seems like needless obfuscation. Likewise, for(;;) can be confusing to people that have never seen it before, whereas while(true) is very intuitive. And there's absolutely no reason to do label: ... goto label;, it's just more confusing.

Answer 3

#define forever for(;;)

forever {
    /*stuff*/
}

Answer 4

When writing code for myself I use for(;;). Other people tend to be confused by its syntax and so for code that other people must see/use, I use while(true).

Answer 5

for (;;)
{
    /* No warnings are generated about constant value in the loop conditional
       plus it is easy to change when you realize you do need limits */ 
}

Answer 6

I use for (;;) in C-style languages and while true in languages that don't support that construct.

I learned the for (;;) method in K&R and it has always felt like idiomatic C to me.
