What is the difference between NULL, '\0' and 0? - Stack Overflow
'\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. Regardless, it's unlikely you'll ever encounter a system which uses an alternative character set like EBCDIC unless you're working on very obscure systems.
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 ...
c++ - What does (~0L) mean? - Stack Overflow
0L is a long integer value with all the bits set to zero - that's generally the definition of 0. The ~ means to invert all the bits, which leaves you with a long integer with all the bits set to one. In two's complement arithmetic (which is almost universal) a signed value with all bits set to one is -1.
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.
windows - Can't access 127.0.0.1 - Stack Overflow
Good question. Just checked redis and it does work on 127.0.0.1. I guess it's because it doesn't use http, but it's special protocol RESP. Will update the question now. To the second part, this is not browser issue, Fiddler (for IIS) and Visual Studio Server Explorer (for azure emulator) both can't connect to 127.0.0.1. –

c - What do 0LL or 0x0UL mean? - Stack Overflow
LL designates a literal as a long long and UL designates one as unsigned long and 0x0 is hexadecimal for 0. So 0LL and 0x0UL are an equivalent number but different datatypes; the former is a long long and the latter is an unsigned long. There are many of these specifiers: 1F // float 1L // long 1ull // unsigned long long 1.0 // double
