**Introduction**
In this programming assignment, you will be adding a class called TCPRequestChannel to extend the IPC capabilities of the client-server implementation in PA3 using the TCP/IP protocol. The client-side and server-side ends of a TCPRequestChannel will reside on different machines.
Since the communication API (not just the underlying functionality and features) through TCP/IP is different from FIFO, you will also need to restructure the server.cpp and client.cpp as part of this programming assignment:
- The server program must be modified to handle incoming requests across the network request channels using the TCP/IP protocol. Specifically, the server must be able to handle multiple request channels from the client residing on a different machine.
- You must also modify the client to send requests across the network request channels using the TCP/IP protocol.
**Tasks**
- [ ] Implement the TCPRequestChannel class
- [ ] write the TCPRequestChannel(string, string) and TCPRequestChannel(int) constructors
- [ ] write the destructor
- [ ] write accept_conn() so the server can accept client connections
- [ ] write cread(void*, int) and cwrite(void*, int) methods
- [ ] Modify client
- [ ] add a and r options
- [ ] change request channel instances to TCPRequestChannel
- [ ] Modify server
- [ ] add r option
- [ ] implement server's primary channel
- [ ] implement server's accept loop
