#includeIn this example, the `SocketInputStream` is created with port number `8080`, which specifies that data will be received from the socket on the specified port. Then, the `>>` operator is used to retrieve the data that has been written to the input stream of the socket, and it is stored in the `message` variable. Finally, the `message` is printed to the console. The `SocketInputStream` class is part of the Boost.Asio library, which is a C++ library for network and low-level I/O programming.#include int main() { SocketInputStream inputStream(8080); std::string message; inputStream >> message; std::cout << "Received message: " << message << std::endl; return 0; }
