This code creates an Asio I/O service, a resolver object for resolving host names and port numbers, a TCP socket object, and a query object for the desired endpoint. Then, it resolves the query using the resolver, obtains a sequence of endpoint descriptors, and connects the socket to the first available endpoint. Package/library: Boost.Asio (part of the Boost C++ Libraries). 2.

This code creates a Qt TCP socket object, connects it to a host and port, sends a message, waits for a response, reads the data, and processes it. If an error occurs, it prints a debug message. Package/library: Qt Network module (part of the Qt framework). 3. Poco Net: A lightweight and modular C++ library for network programming, which provides support for TCP, UDP, HTTP(S), and other protocols. Code example:c++ #include
