title: A time counter in c++
body: <p>I want to programme a code in C++ that makes a time-counting at the same time while we are waiting the user to  enter for example the integer result we want to see.For instance we want user to enter two integers and select one of the four operations,then write down the result.Meanwhile the clock or the counting machine starts to count the seconds until the user write down the result.
  Is it possible to do in C++,if it's not how can I do this?
  Thanks...  </p>
