- What is the difference between 0. 0. 0. 0, 127. 0. 0. 1 and localhost?
0 0 0 0 has a couple of different meanings, but in this context, when a server is told to listen on 0 0 0 0 that means "listen on every available network interface" The loopback adapter with IP address 127 0 0 1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0
- factorial - Why does 0! = 1? - Mathematics Stack Exchange
$\begingroup$ The theorem that $\binom{n}{k} = \frac{n!}{k!(n-k)!}$ already assumes $0!$ is defined to be $1$ Otherwise this would be restricted to $0 <k < n$ A reason that we do define $0!$ to be $1$ is so that we can cover those edge cases with the same formula, instead of having to treat them separately
- What is IPV6 for localhost and 0. 0. 0. 0? - Stack Overflow
The 0 0 0 0 and :: addresses are reserved to mean "any address" So, for example a program that is providing a web service may bind to 0 0 0 0 port 80 to accept HTTP connections via any of the host's IPv4 addresses These addresses are not valid as a source or destination address for an IP packet
- What is the difference between NULL, \0 and 0? - Stack Overflow
NULL is not guaranteed to be 0 -- its exact value is architecture-dependent Most major architectures define it to (void*)0 '\0' will always equal 0, because that is how byte 0 is encoded in a character literal I don't remember whether C compilers are required to use ASCII -- if not, '0' might not always equal 48
- Regex that accepts only numbers (0-9) and NO characters
CAUTION: In JavaScript, \d is equivalent to [0-9], but in NET, \d by default matches any Unicode decimal digit, including exotic fare like ႒ (Myanmar 2) and ߉ (N'Ko 9) Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions ECMAScript flag)
- What is %0|%0 and how does it work? - Stack Overflow
@Pavel: What a bat file does is: read instruction, at the end of file terminate If you run %0: Process 1: starts, run %0 (thus create process 2); then die Process 2: starts, run %0 (thus create process 3); then die [ ] you alway have at most 2 process running because the creator will die
- What does javascript:void (0) mean? - Stack Overflow
The void operator is often used merely to obtain the undefined primitive value, usually using “void(0)” (which is equivalent to “void 0”) In these cases, the global variable undefined can be used instead (assuming it has not been assigned to a non-default value)
- c - why is *pp[0] equal to **pp - Stack Overflow
For example, int i, j=0; i=j; effectively dereferences j; j is an address constant, and the assignment concerns the value stored there, j's value, so that the assignment amounts to i=0 Other languages, like Algol68, were more precise: one would effectively write int i; int *pi = i; , which makes complete sense (pi now points to i)
