Convert Milliseconds to Duration with the given format

Question

For a given duration of 203443 milliseconds (this is 3 minutes, 23 seconds and 443 milliseconds), a pattern like e.g.

This took about' m 'minutes and' s 'seconds.

would produce the following formatted output:

This took about 3 minutes and 23 seconds.

It is different from format timestamp to current date-time. Is there any C++ standard Library (under C++14) or a solution that I can follow. I'm new to C++.

Answer 1

#include <chrono>
#include <iostream>

int
main()
{
    using namespace std::chrono;
    auto d = 203443ms;
    auto m = duration_cast<minutes>(d);
    d -= m;
    auto s = duration_cast<seconds>(d);
    std::cout << "This took about " << m.count() << " minutes and "
                                    << s.count() << " seconds.\n";
}
