   • What is a function with a class type called in C++?

     Top Answer

     Answered Jul 22, 2019 · 2 votes

     What is this called?

     move is the name of a free function. The full signature action move() tells you that its return value is an instance of type action and that the functions doesn't expect any parameters. Note that free functions are different from member functions in that they don't have a special relationship to any class.

     How do I use the constructor of the class?

     The constructor is called when you create an instance of that class. Example:

     action instance; // calls default constructor-

     Note that you don't really invoke constructors directly. In the above case, it's a declaration that leads to a call to action::action().

     what should I return in the function move?

     An instance of action, because the function signature says so:

     action move() { return action{}; }-

     If your constructor takes parameters, here's an adjusted example:

     struct action { action(int n) { /* do stuff with the argument... */ }};-action move() { return action{42}; }-

   • What exactly is the info_Hash in a torrent file

     Top Answer

     Answered Nov 30, 2018 · 72 votes

     So I finally figured it out.

     The “infohash” is the SHA1 Hash over the part of a torrent file that includes:

     • ITEM: length(size) and path (path with filename)
     • Name: The name to search for
     • Piece length: The length(size) of a single piece
     • Pieces: SHA1 Hash of EVERY piece of this torrent
     • Private: flag for restricted access

     To show this a little more I took a random torrent file and used the “BEncode Editor” from Ultima to make it more clearly to me.

     As you can see the the red box marked the information part of the torrent file. The torrent file includes not the Hash of the items, but the hashes of every piece.

     • For item1 with: 1069496548
     • and item2 with: 223
     • It is together: 1069496771
     • With a piece size of: 524288
     • There are 2040 pieces. (1069496771/524288=2039.9032 approximately)
     • The pieces section includes 40800 byte of data what are 81600 + 2 chars in the file.
     • the +2 because 0x marks that this is hexadecimal.
     • A SHA1 hash has 40 0x chars or 20 Byte of data what are 2040 SHA1 hashes.

     I am sorry that this information is about a torrent that leads to a illegal movie, but i wanted to use a torrent that realy exists.

   • What is an individual instance of a data type called?

     Top Answer

     Answered Jan 14, 2016 · 5 votes

     This is called state. Talking about every possible state you're looking for the term state space.

     An 8-bit byte has 256 possible states because there are two possible states per bit so you have 2^8 states. A C-style struct with two boolean members can have four states or 2^2. Two bytes and you're looking at 256^256 states. State space gets big fast.

   • What is called '../' in a relative file/folder path?

     Top Answer

     Answered Sep 06, 2022 · 0 votes

     Briefly, it is called levelup notion.

     Let's start with defining path:

     A path is a slash-separated list of directory names followed by either a directory name or a file name. A directory is the same as a folder.

     Then, we look at types of paths: Absolute and relative paths!

     An absolute, or full, path begins with a drive letter, whereas a relative path refers to a location that is relative to a current directory.

     In relative paths we may use dot and double-dot symbols. A dot here means the current directory itself. And the double-dot notation, which is called level-up, is used for moving up in the hierarchy.

     • Now to change the directory using the dot notion we do as follows:A single dot represents the current directory itself. for example:in a command line interface (e.g. PowerShell):

     cd . will not change the directory as itself point to the current directory.

     • To change the directory using the level-up notion we do as follows:each double-dot notions takes you one level up, meaning one folder closer to the base drive or root folder in the hierarchy.Look at the example below for different cases of using levelup notions:

   • What is the file type of a kernel (Linux kernel for example)?

     Top Answer

     Answered Jun 22, 2015 · 6 votes

     The Linux Kernel (or any other OS Kernel) is just a binary image containing machine code for the target architecture. It is kinda like a statically linked executable, because there's no operating system to link any dependecy before it's running,so that once loaded in the main memory, it is able to execute without any other helper. This doesn't mean that it cannot load any other module dynamically. In Linux, this behavior is easily seen when you load a module from userspace (it's different process from loading a .so file tough).

     That image may be compressed before being stored in the filesystem, and that's why you may get something like this output from "file":

     file /boot/vmlinuz-2.6.39-400.215.7.el6uek.x86_64

     /boot/vmlinuz-2.6.39-400.215.7.el6uek.x86_64: Linux kernel x86 boot executable bzImage, version 2.6.39-400.215.7.el6uek.x86_64 , RO-rootFS, swap_dev 0x3, Normal VGA

   What is bencoding in BitTorrent?

   • Bencoding is most commonly used in torrent files, and as such is part of the BitTorrent specification. These metadata files are simply bencoded dictionaries. Bencoding is simple and (because numbers are encoded as text in decimal notation) is unaffected by endianness, which is important for a cross-platform application like BitTorrent.

   How is a torrent formed?

   • If the torrent contains multiple files, the pieces are formed by concatenating the files in the order they appear in the files dictionary (i.e., all pieces in the torrent are the full piece length except for the last piece, which may be shorter). All strings must be UTF-8 encoded, except for pieces, which contains binary data.
