Web13 hours ago · By using variable-length subnetting, network administrators can allocate subnets of varying sizes based on the number of hosts required in each subnet. For instance, if an organization requires 5 hosts in one particular subnet and 15 hosts in another, assigning the same mask length to both subnets would result in wastage of IP addresses. Web6.18 Arrays of Length Zero. Declaring zero-length arrays is allowed in GNU C as an extension. A zero-length array can be useful as the last element of a structure that is really a header for a variable-length object: struct line { int length; char contents [0]; }; struct line *thisline = (struct line *) malloc (sizeof (struct line) + this ...
