The above network is using class ,C, network ,mask, and /29 subnet ,mask, means network IP can be divided into 8 subnets. Each router has a unique IP address for each linked subnetwork. There is an important point to be noticed that the more the ,bits, we carry from the subnet ,mask, for host ID then the more will be the subnets obtainable for the network.

2/10/2020, · Pointers and non-const references to ,bit, fields are not possible. When initializing a const reference from a ,bit, field, a temporary is created (its type is the type of the ,bit, field), copy initialized with the value of the ,bit, field, and the reference is bound to that temporary. The type of a ,bit, field can only be integral or enumeration type.
