Problem 1: Numeric addresses for computers using the IPV4 format are composed of four parts, separated by periods in the form of aa.bb.cc.dd where aa, bb, cc, and dd are integers larger or equal to zero. Locally, computers are usually known by a nickname as well. Write a C program to process a list of IPV4 addresses identifying all pairs of computers from the same locality. Create a new structure type named address_t with components for the four integers of the IP address and a fifth component in which to store an associated nickname of up to 15 characters. Your program should read a list of addresses and nicknames from a file (maximum 300 addresses) terminated by a sentinel IP address of all zeros and a sentinel nickname (sample file here). It should then print a list of messages identifying each pair of computers from the same locality, that is, each pair of computers with matching values in the first two components of the address. In the messages, the computers must be identified by their nicknames. Ex: Servers mirkwood and gandalf are on the same local network. For this purpose, you must write a function named localnet that takes two IP structured variables and returns true (1) if they are on the same local network and false (0) if not. Follow the messages by printing the full list of addresses and nicknames.
