    try {
        server.open().wait();
        std::cout << 'Listening on ' << url << std::endl;

    }

    return 0;
}

Code Output:

Listening on http://localhost:6502/

Code Explanation:

Let’s unravel this kinda complex C++ code, shall we?

First off, a bunch of libraries are herded at the start: <iostream> is your basic C++ cout and cerr buddy, <cpprest/...> is part of the C++ REST SDK, which is the sugar, spice, and everything nice needed for crafting a web server in C++.

The namespaces are used coz who writes std:: every single time? Not this coder, no siree!

Now let’s break it down:

• handle_get: This is where the GET requests are… well, handled. It’s expecting some JSON action, but we’re just saying ‘Hello, World!’ in nerdy C++ style.
• handle_request: This is the Jack-of-all-trades. It processes requests in a generic way, and you can funk it up with your logic to create responses.
• WebServer class: It’s the heart of it all! http_listener listens for HTTP requests; initHandlers is where it’s told how to deal with different HTTP methods.

The main function kicks things off. It crafts a WebServer object, yells at it to wake up and listen to http://localhost:6502/, and then, well, it just hangs there with an infinite loop (classic, right?).

If you swing an HTTP GET request at this server, it should sing back with a JSON message saying, ‘Welcome to C++ Web Development!’ If it doesn’t, then I guess it’s taking a nap or something crashed.

So, yeah, that’s the lowdown on creating a simple web server with C++. Who said C++ can’t do web stuff? They sure didn’t see this block of digital art. It’s alive! It’s alive!

Thanks for sticking around, and remember, a coder who doesn’t test their code is like a comedian who doesn’t laugh at their own jokes! Keep your brackets close, and your exceptions closer! ✌️😉
