How to declare multiple deadline timer in class definition?

Question

I have managed to declare one deadline timer in a class.

class myTimerService
{
public:
    boost::asio::io_service ioService;
    myTimerService():t0(ioService){}
private:
    boost::asio::deadline_timer t0;
};

so the construct is able to construct the t0. How do I modify it to have another deadline_timer t1. How would the construct look like for following?

class myTimerService
{
public:
    boost::asio::io_service ioService;
    myTimerService()-------????
private:
    boost::asio::deadline_timer t0;
    boost::asio::deadline_timer t1;
};

myTimerService():t0(ioService), t1(ioService) {} perhaps? – Hajo Kirchhoff Jan 27 '22 at 16:10 — Hajo Kirchhoff, Jan 27 '22 at 16:10
that worked, thank you. – Ashvtosh Goel Feb 02 '22 at 15:56 — Ashvtosh Goel, Feb 02 '22 at 15:56

As the commenter said, base & member initializer list is comma-separated:

#include <boost/asio.hpp>
class myTimerService {
  public:
    boost::asio::io_service ioService;
    myTimerService() : t0(ioService), t1(ioService) {}

  private:
    boost::asio::deadline_timer t0;
    boost::asio::deadline_timer t1;
};

However, I'd suggest NSMI:

#include <boost/asio.hpp>

class myTimerService {
    boost::asio::io_service     ioService;
    boost::asio::deadline_timer t0{ioService}, t1{ioService};
};
