How can I use Boost.Asio for TCP communication in C++?

You can use Boost.Asio to create TCP clients and servers. Start by including the necessary headers and initializing the io_context.

Can you provide a simple example of a TCP client?

Sure! Here's a basic example:

#include <boost/asio.hpp>
#include <iostream>

int main() {
    boost::asio::io_context io_context;
    boost::asio::ip::tcp::socket socket(io_context);
    socket.connect(boost::asio::ip::tcp::endpoint(boost::asio::ip::address::from_string("127.0.0.1"), 12345));
    // Send and receive data here
}

This connects to a server running on localhost at port 12345.

What about error handling in Boost.Asio?

Error handling can be done using exceptions or checking the return values of functions. Always ensure to handle potential errors gracefully.

Is Boost.Asio suitable for high-performance applications?

Yes, Boost.Asio is designed for high-performance networking applications and can handle many connections efficiently.
