what does

for (; ; )
{
  // do something
}

mean in c#?

Isn't there supposed to be (initializer, condition, iterator) ?

I saw an example in a book that uses nothing inside the contents of the for loop.

Answer 1

That would create an unconditional (infinite) loop which has no initializer or iterator.

same as

while(true)
{
...
}

You'll have to use break; to get out of the loop.

Answer 2

At warning level 4 compilers complain about conditional expressions that always evaluate to true, such as while(1) or while(true).

So a common way to suppress the compiler warnings for that is to use for (;;) blocks.

(Im not saying its a good practice), but if you have to create code that compiles at warning level 4 its a habit to use for (;;) instead of while (true).
