Implement an HTTP/1.1 Server That Serves a File

Write a C program that implements a simple HTTP/1.1 server. The server should parse incoming requests and serve a static file or a directory listing.

Requirements:

• Create a TCP socket, bind to a port (e.g., 8080), and listen for connections
• Accept a client connection and read the HTTP request
• Parse the request line to extract the method (GET) and URI
• Construct an HTTP/1.1 response status line
• If the URI maps to an existing file, read it and send a 200 OK response
• Include Content-Length and Content-Type headers
• If the file is not found, send a 404 Not Found response
• Show the raw HTTP response construction with printf
• Do not use any external HTTP libraries
