clent server communication using objectives

The subject of this programming assignment is writing a simple client-server application that uses (network) sockets. The client-server application that you are to write is to allow one to copy a file from the (remote) server machine to the local machine. The particular application protocol that your client and server are to implement will be referred to as the remcp application protocol. It is specified below. Since this lab involves both a server program and a client program, it is to be implemented in two separate files, to be named: (1) lab4-server.c and (2) lab4-client.c. Each file must be able to be compiled into an executable, which mean each must contain a main, etc. Assume that compilation will produce the following executables: server: remcpd client: remcp remcp Application Protocol: A key element of client-server systems is the application protocol that both the client and the server must adhere to. An application protocol specifies exactly what messages must be exchanged between the client and the server, the order in which they are to be exchanged, and their format. If either the client or the server fails to exactly follow the protocol, they will not function together properly. Not only will your client and server programs be tested with each other, your client will be tested against the server solution, and your server will be tested against the client solution.
