Assignment Overview

In this assignment, we implemented the client and server for a simple chat service. The Simple Broadcast Chat Protocol (SBCP) is a protocol that allows clients to join and leave a global chat session, view members of the session, and send and receive messages

• An instance of the server provides a single “chat room,” which can only handle a finite number of clients.
• Clients must explicitly JOIN the session. A client receives a list of the connected members of the chat session once they complete the JOIN transaction.
• Clients use SEND messages to carry chat text, and clients receive chat text from the server using the FWD message.
• Clients may exit unceremoniously at any time during the chat session.
• The server should detect a client exit, cleanup the resources allocated to that client and notify the other clients.
• Also, both the client and server handle several inputs at the same time using I/O multiplexing (select).

Steps to compile and run

1. In order to compile the code, make sure the makefile, client.c and server.c are in the same directory/folder/. Type in the command:

   make
   

2. To start the server, type in the command line:

   ./server server_ip server_port max_clients
   

3. To start the client, type in the command line: ./client IPAdr Port

   ./client username server_ip server_port
   

Note: - The code is written in C and is compiled and tested in a Linux environment.
