How to Create a Simple Client-Server Program Using C Sockets
- Sockets are crucial for network communication, allowing data exchange over networks using programs.
- This guide focuses on building a simple TCP-based client-server application in C for both beginners and experienced programmers.
- The tutorial covers socket programming basics while creating a functional client-server system.
- To start, you need a C Compiler (like GCC), a text editor, and necessary libraries (e.g.,
). - The server side involves creating a socket, binding it to an IP and port, listening for connections, accepting a client, and data exchange.
- The client side includes socket creation, defining the server's address, connecting to the server, sending data, and receiving responses.
- Troubleshooting tips are provided for common socket programming issues like 'Address already in use' and 'Connection refused.'
- Suggestions for enhancing the program are discussed, such as multi-client support, custom protocols, and error logging.
- Running the program involves compiling the code, starting the server, running the client, and observing client-server interactions.
- This tutorial empowers you to understand and implement socket programming in C, a skill applicable in various domains like web servers and IoT devices.
