Your second homework focuses on TCP/IP and network programming. Please follow the lectures to write programs using C/C++ 1. (a) A host in an organization has an IP address 150.32.64.34 and a subnet mask 255.255.240.0. What is the address of this subnet? What is the range of IP addresses that a host can have on this subnet? (b) A university has 150 LANs with 100 hosts in each LAN. Suppose the university has one Class B address. Design an appropriate subnet addressing scheme. 2. Using C/C++ and sock programming, write both the client and server programs to implement a task. You can choose the task by yourself (e.g. a chatting application between the server and the client, or a file transfer application between the server and the client, etc.) In the hardcopy, please write clearly what your server program and client programs do
