How to simulate time in C++

[curiously enough]

How do I simulate time in C++?
For example I want:

printf("\a\a\a");
half a second passes;
printf("\a\a");

I'd recommend the Sleep() function.

It depends on what libraries you've got. The sleep function is not part of the language specification, so it isn't present on all platforms.

I'm not familiar with the C++ Standard Library, but in C the most portable method is to spin on the time() function until difftime() tells you that the desired amount of time has passed. Refer to <time.h>.

A spin-loop like this is just about the worst thing you can do in a multi-tasking environment. You may have to use a nonportable technique. If so, then we would need to know more about your run-time environment -- especially what operating system you're using.

Hi!

You can use also the function delay(millisec) ; (#include <dos.h>)
when it possible in your system

Well this will depend on how precise you need the timer. On a windows platform you can use GetTickCount() if you only need the time in milliseconds and you don't need a long lasting timer. You can also create a timer, but its best if you just read up on them.. If you need a more percise timer you can goolge for high resolution timers in C++ and come up with a lot of information about them.
