C++ How to print "Hello world" in OTCv8 in terminal

[lexus21]

Hello, i want to write simple code in c++ to otcv8. I created a file called com.cpp in the project (microsoft visual studio) in sources->client.
Now I put the following code there:

#include <iostream>

int badname() {
std::cout << "Hello, world!" << std::endl;
return 0;
}

otclient is comiling but, i can't see Hello world! after launch otclient in terminal, how to print "Hello World" in otclient in terminal every 1 sec?

g_logger.info("Hello, world!"); --> Hello, world!
int myNumber = 7; g_logger.info(stdext::format("This is my number: %d!", myNumber)); --> This is my number: 7!

int myNumber = 7; g_logger.info("This is my number: %d!", myNumber); --> This is my number: 7!

You will need to format that string, info won't do it for you. Since he uses v8 then it would be g_logger.info(stdext::format("This is my number: %d!", myNumber));

Forgot that. Ty.

so, I managed to print "Hello world" in the terminal. Thank you for your help.
I needed this to generally understand how it works.
Now, I want the code to display the value from COM5 every second.
I hope I'm doing well.

com.cpp

#include <boost/asio/read.hpp>
#include <boost/asio/write.hpp>
#include <boost/bind.hpp>
#include <iostream>
#include "framework/global.h"
#include "com.h"


COM g_com;

COM::COM() : port(io_service, "COM5") {
    // Configure serial port settings (move from init() to constructor)
    port.set_option(boost::asio::serial_port_base::baud_rate(9600));
    port.set_option(boost::asio::serial_port_base::character_size(8));
    port.set_option(boost::asio::serial_port_base::parity(boost::asio::serial_port_base::parity::none));
    port.set_option(boost::asio::serial_port_base::stop_bits(boost::asio::serial_port_base::stop_bits::one));
    port.set_option(boost::asio::serial_port_base::flow_control(boost::asio::serial_port_base::flow_control::none));
}

void COM::init() {
    // Create io_service object
    boost::asio::io_service io_service;

    // Declare a buffer to store received data

    // Asynchronously read data into the buffer
    boost::asio::async_read(port, buffer,
        [this](boost::system::error_code error, std::size_t bytes_transferred) {
            if (!error) {
                // Process the received data
                std::istream is(&buffer);
                std::string line;
                while (std::getline(is, line)) {
                    std::cout << line << std::endl;
                }

                // Asynchronously read the next fragment of data
                boost::asio::async_read(port, buffer,
                    [this](boost::system::error_code error, std::size_t bytes_transferred) {
                        if (!error) {
                            // Process the received data
                            g_logger.info(stdext::format("This is my output form com: %s", boost::asio::buffer_cast<const char*>(buffer.data())));

                        }
                        else {
                            // Error handling
                            g_logger.info("Error");
                        }
                    });
            }
            else {
                // Error handling
                std::cerr << "Error reading from serial port: " << error.message() << std::endl;
            }
        });

    // Run the event loop to process asynchronous operations
    io_service.run();
}

void COM::terminate() {
    g_logger.info("Bye!");
}

and com.h

#ifndef COM_H
#define COM_H

#include <boost/asio.hpp>

class COM {
public:
    COM(); // Constructor
    void init();
    void terminate();

private:
    boost::asio::io_service io_service;
    boost::asio::serial_port port;
    boost::asio::streambuf buffer;
};

extern COM g_com;

#endif

i don't know why but i have

the port is underlined (
(local variable) boost::asio::serial_port port)

can't compile the code

how to solve it?
What could be changed in the code?

I don't know if this will work.


edit. program is compiling but no output in terminal in otclient - i know this code is not easy but thank you for any tip
