size

I am creating an app using the Bespin editor and HTML5's localStorage. It stores all files locally and helps with grammar, uses JSLint and some other parsers for CSS and HTML to aid the user. I want to calculate how much of the localStorage limit has been used and how much there actually is. Is this possible today? I was thinking for not to simply calculate the bits that are stored. But then again I'm not sure what more is there that I can't measure myself. You may be able to get an approximate idea by using the JSON methods to turn the whole localStorage object to a JSON string: JSON

用链表创建队列 public class LinkQueue<E> implements Queue<E>{ public class Node{ public E e; public Node next; public Node(E e , Node next){ this.e = e ; this.next = next; } public Node(E e){ this.e = e; this.next = null; } public Node(){ this(null,null); } @Override public String toString(){ return e.toString(); } } private Node head; private Node tail; private int size; public LinkQueue(){ head = null; tail = null; size = 0; } @Override public int getSize() { return size; } @Override public boolean isEmpty() { return size == 0; } @Override public E dequeue() { // 1.队列为空 即队首为空 if(head == null){

I tried printf("%d, %d\n", sizeof(char), sizeof('c')); and got 1, 4 as output. If size of a character is one, why does 'c' give me 4? I guess it's because it's an integer. So when I do char ch = 'c'; is there an implicit conversion happening, under the hood, from that 4 byte value to a 1 byte value when it's assigned to the char variable? Richard Pennington In C 'a' is an integer constant (!?!), so 4 is correct for your architecture. It is implicitly converted to char for the assignment. sizeof(char) is always 1 by definition. The standard doesn't say what units 1 is, but it is often bytes. Th
