What are some examples of socket programming in C++?

Socket programming in C++ allows for communication between devices over a network. Here are a few examples:

1. A simple TCP client-server application.
2. A UDP echo server.
3. A multi-threaded server handling multiple clients.

Can you explain how to create a TCP client-server application?

Sure! To create a TCP client-server application in C++, you need to:

1. Include the necessary headers like <sys/socket.h> and <netinet/in.h>.
2. Create a socket using socket().
3. Bind the server socket to an address using bind().
4. Listen for incoming connections with listen().
5. Accept connections using accept() on the server side.
6. Use send() and recv() for communication.

What libraries do I need to include for socket programming?

You typically need to include the following libraries:

• <sys/socket.h> for socket functions.
• <netinet/in.h> for internet address family.
• <arpa/inet.h> for address conversion functions.
• <unistd.h> for close() function.

Are there any resources for learning more about this?

Yes! You can check out online tutorials, documentation like the Beej's Guide to Network Programming, or books on C++ networking.
