Question

I am confused by the for(;;) construct. I think it is a form of shorthand for an unlimited for loop but I can’t be sure.

Here is the code:

for(;;)
{
    //whatever statements
}

Answer 1

Your guess is correct; it’s an infinite loop.^* This is a common C idiom, although many people (including me) believe the following to be less cryptic:

while (1) { whatever statements; }

_{* It’s infinite assuming there are no break/return/etc. statements inside the loop body.}
