Question

Locally, computers are often known by an alias (nickname) as well. You will design and write a program to process a list of internet addresses from file "C$222_Inet.txt. Your program should read a list of up to 100 addresses and nicknames terminated by a sentinel address of all zeros and the sentinel nickname, "none". Sample CS222 Inet.txt 11122.3.44 platte 131.250.95.21 jet 172.66.788 wabash 111.22.5.66 green 131.250.47.63 baker 0.0.0.0 none For this assignment, you will create your own test data files using the sample format. Grading will involve using different data files with the same Your program will generate a report listing all computers from the same locality--that is, each computer with matching values in the first two components of the address. In the list, the computers should be identified by their alias. The report will be saved to file "222 Locality Report.The user will also generate a report listing all of the computers sorted alphabetically by alias. This report will be saved to file "222 Alias List. As wwith HW3, both reports will comtain the user's name and current date, along with the generated report listing.
