This document explains the functioning of a simple chatroom application implemented in C++ using socket programming. The application consists of two parts: a server and a client.
The server side of the application performs the following tasks:
- Socket Creation: It starts by creating a socket using the
socket
function. - Setting Socket Options: The
setsockopt
function is used to attach the socket to the server port (8080 in this case). - Binding: The
bind
function binds the server to a specific address and port. - Listening: It listens for incoming connections using the
listen
function. - Accepting Connections: The server accepts a connection using the
accept
function. - Communication Loop:
- The server reads messages sent by the client using the
read
function. - It then echoes back the received message to the client using the
send
function. - If the received message is "exit", the server breaks the loop and closes the connection.
- The server reads messages sent by the client using the
The client side of the application performs these operations:
- Socket Creation: It creates a socket similar to the server.
- Connecting to the Server: The client uses the
connect
function to connect to the server at the specified IP address and port. - Communication Loop:
- The client sends messages to the server using the
send
function. - It then waits to receive a message from the server, which is an echo of the sent message.
- If the user types "exit", the client breaks the loop and the connection is closed.
- The client sends messages to the server using the
This basic chatroom application demonstrates the fundamentals of network programming in C++, particularly socket programming. The server and client communicate over TCP, with the server echoing back whatever message the client sends.
