Add features to a TCP server in c

Hello, I got my 2 files (client.c and server.c). I am able to connect a client to the server but I want to add features: For the server: - When a client joins the server, the server prompt should print the socket descriptor that has joined. e.g. "Client has joined: 5" - The server should print out all messages it receives from each of the clients. - The server will execute each message that it receives from a client. (i.e. When a client receives a message, it will fork() a new process and run the 'system' to try to run that command on the server.) For the client: - A client may send as many messages to the server as it likes once it has connected. - A client socket should leave the server when the user types 'exit' in the prompt. (When a client leaves the server, the server should still persist waiting on other client)
