Dec 22, 2014 · 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 …

May 29, 2017 · The default route in Internet Protocol Version 4 (IPv4) is designated as the zero-address 0.0.0.0/0 in CIDR notation, often called the quad-zero route. The subnet mask is given as /0, which effectively specifies all networks, and is the shortest match possible. The other would be for IPv6. Source Default Route. AWS Documentation

Nov 4, 2010 · O(1) means it takes a constant time, that it is not dependent on how many items are in the list. O(n^2) means that for every insert, it takes n*n operations. i.e. 1 operation for 1 item, 4 operations for 2 items, 9 operations for 3 items. As you can see, O(n^2) algorithms become inefficient for handling large number of items.

Jan 16, 2017 · De fato há algumas implementações que o valor é 0 mesmo. Mas é mais comum o valor (void *)0, deixando claro que na verdade esse é um ponteiro para o endereço zero da memória, portanto um ponteiro nulo. Um 0 não é tão intercambiável assim. Se tentar comparar um NULL, ou seja void * com 0 até funciona porque ele faz um cast automático.

Jan 31, 2013 · @unwind: note also that 0 is an octal integer constant, and is a special case of the fact that in general one can write 0[0-7]* for an octal integer constant. Not that it makes any difference whether 0 is formally defined to be an octal vs decimal constant, but as it happens the grammar classifies it as octal, as it does the \0 escape :-) –

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.

Dec 26, 2013 · 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 ...

Jan 27, 2016 · 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).

Aug 13, 2020 · @GabrielStaples Have you retested this with the latest releasd gcc (v13.2.0 as of Jan 2024)? -Og seems to have improved debuggability and the aforesaid issue doesn't arise (in my trials). In that case, this answer perhaps warrants an update. –
