How to update time & date in C++?

I am new to C++. I used the following function get the time:


time_t currentTime;


time(%26amp; currentTime);


cout %26lt;%26lt; asctime(localtime(%26amp; currentTime));





But the time does not change unless I refresh the page%26gt; Could someone show how to update the time on the screen?
