reading from boost asio socket and printing to terminal - c++

Question

I want to use boost asio sockets to send a message from the server to the client and then print it out to the client terminal. I am trying to send the message "hello". It doesn't work. How can i fix this?
Thanks!
client:
#include <boost/asio.hpp>
#include <iostream>
#include <string>
using namespace std;
int main (int argc, char* argv[]) {
try {
boost::asio::io_service io_service;
boost::asio::ip::tcp::resolver::query query("localhost", "41005");
boost::asio::ip::tcp::resolver resolver(io_service);
boost::asio::ip::tcp::resolver::iterator destination = resolver.resolve(query);
boost::asio::ip::tcp::resolver::iterator end ;
boost::asio::ip::tcp::endpoint endpoint;
while ( destination != end ) {
endpoint = *destination++;
std::cout<<endpoint<<std::endl;
}
boost::asio::ip::tcp::socket socket(io_service);
socket.connect(endpoint);
boost::array< char, 128 > buf;
boost::system::error_code error;
std::size_t length = boost::asio::read(socket, boost::asio::buffer(buf, 512), boost::asio::transfer_all(), error);
cout << length;
}
catch (std::exception& e)
{
std::cerr << e.what() << std::endl;
}
return 0;
}
server:
#include <boost/asio.hpp>
#include <iostream>
#include <string>
using namespace std;
int main () {
try {
boost::asio::io_service io_service;
boost::asio::ip::tcp::acceptor acceptor(io_service, boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), 41005));
for (; ;) {
std::cout<<"Listening to"<<std::endl;
boost::asio::ip::tcp::socket socket(io_service);
acceptor.accept(socket);
std::string message = "hello";
boost::system::error_code ignored_error;
boost::asio::write(socket, boost::asio::buffer(message), boost::asio::transfer_all(), ignored_error);
}
}
catch (std::exception& e)
{
std::cerr << e.what() << std::endl;
}
return 0;
}

classic error: the "acceptor.accept" method is a blocking call, so the hello part is never called.
Our COut friend would help you, as allways:
...
std::cout<<"Sending hello"<
