```cpp

    auto now = [] {

        return std::chrono::duration_cast(std::chrono::steady_clock::now().time_since_epoch())

            .count();

    };

    std::cout << "Physical memory usage: " << Process::getPhysicalMemorySize() / 1024 << "KB" << std::endl;

    std::cout << "Total CPU time: " << Process::getTotalProcessorTime().count() << "ms" << std::endl;

    auto t1 = now();

    while (now() - t1 <= 5) {

        static std::size_t i = 0;

        (void)(i++);

    }

    std::cout << "Total CPU time (+5s): " << Process::getTotalProcessorTime().count() << "ms" << std::endl;

    std::cout << "Physical memory usage (+10MB): " << Process::getPhysicalMemorySize() / 1024 << "KB" << std::endl;

    vb.resize(1);

    vb.shrink_to_fit();

    std::cout << "Physical memory usage (-10MB): " << Process::getPhysicalMemorySize() / 1024 << "KB" << std::endl;

}

```

_**Program output:**_

Total CPU time: 0ms

Total CPU time (+5s): 5609ms

Physical memory usage: 4212KB
