Strange loops

Code:

---

for ( ; ; )
{
  //code here
}

---

What does it do? Is it an infinite loop or something?

Yes. It keeps going until you use break; :)

It is however, more proper to use a While loop for that purpose.

Not so sure, I think you can use both, since I've seen lots of usages of both

Code:

---

while(1) { }

---

and

Code:

---

for(;;) { }

---

i'd use for(;;){} , looks better ;) i guess it's a qwestion of taste, anything for can do, can be done with while and vice versa

Notice the smilies that come up when you type for(;;)

yeah ;) i didn't bother turn off the smilies or put in a space, it looks funny :p
