How can data be sent to a server without blocking the main execution thread?

To send data to the server without blocking the main thread in C/C++, multithreading can be used. For example, creating a separate thread that handles sending data while the main thread continues working.

Example using std::thread:

#include <iostream>
#include <thread>
#include <chrono>

void sendDataToServer() {
    // Simulate data sending
    std::this_thread::sleep_for(std::chrono::seconds(2));
    std::cout << "Data sent to server" << std::endl;
}

int main() {
    std::thread sender(sendDataToServer);
    std::cout << "Main thread continues work" << std::endl;
    sender.join(); // Wait for sending to finish if needed
    return 0;
}

You can also use asynchronous calls (std::async) or libraries for async I/O, such as Boost.Asio.
