What does "for(;;)" mean?
(5 answers)
Closed 7 years ago.
Simple question: I've been looking over boost's asio library, and keep coming across code like this.
for(;;){
//something
}
There's an example of this here.
Can anyone elaborate as to what using ";;" within a for loop does? I can't seem to understand it.
Its a simple infinite loop syntax, a complete code looks like this
for(<initialize>; <condition>; <increment/decrement>) {
<body>
}
Those I labelled with '< .. >' are optional.

this is a quick question, Im translating a program that's in C++ to C, and I saw this line of code,
for (int v : adj[u]) {
referenced in this article: link
and I am not really sure what it does. I tried googling it and got results for range based for loops in C++, but cannot find anything that has this exact syntax and what it means. Help would be much appreciated.
It's a very simple for loop that iterates over the elements of adj[u], going 1 by 1.

Greeting, You! I am learning Kotlin and I am struggling to use while loop to get answer from user. Not just that, if you could help explain how to use while loop to me, I would be really appreciate and thanks in advance.
You should use while(ans == 'Y').
In condition checking you should make use of == to check equality
And also in order to get repeated input put the readLine statement inside while loop.

How does an empty for works?
I have seen this code (and works perfectly)
for(;;) {
And I can't comprehend how is this working or why
It is exactly like while(true).
It skips all the conditions so it just empty-executes since in for the expressions are all optional (i.e. you don't have to provide them if you choose not to).
