to simulate a 'work-in-progress report', you might consider:

<pre><code>// start thread to do some work
m_thread = std::thread( work, std::ref(*this)); 

// work-in-progress report
std::cout &lt;&lt; "\n\n ... " &lt;&lt; std::flush;
for (int i=0; i&lt;10; ++i) // for 10 seconds
{
 std::this_thread::sleep_for(1s); // 
 std::cout &lt;&lt; (9-i) &lt;&lt; '_' &lt;&lt; std::flush; // count-down
}

m_work = false; // command thread to end
m_thread.join(); // wait for it to end
</code></pre>

With output:

<blockquote>
 ... 9_8_7_6_5_4_3_2_1_0_
 
 work abandoned after 10,175,240 us
</blockquote>

Overview: The method 'work' did not 'finish', but received the command to abandon operation and exit at timeout. (a successful test)

The code uses chrono and chrono_literals.

I want to add a delay so that one line will run and then after a short delay the second one will run. I'm fairly new to C++ so I'm not sure how I would do this whatsoever. So ideally, in the code below it would print "Loading..." and wait at least 1-2 seconds and then print "Loading..." again. Currently it prints both instantaneously instead of waiting.

<pre><code>cout &lt;&lt; "Loading..." &lt;&lt; endl;
// The delay would be between these two lines. 
cout &lt;&lt; "Loading..." &lt;&lt; endl; 
</code></pre>

我想添加一个延迟，这样一行将运行，然后在短时间延迟后，第二行将运行。我对C++相当陌生，所以我不知道我会怎么做。因此，理想情况下，在下面的代码中，它会打印“加载.”等待至少1-2秒，然后打印“加载.”再来一次。目前，它同时打印两个，而不是等待。cout << "Loading..." << endl;// The de...
