Hi.
I study C. I need a function or something that will cause delay of given number of seconds, like delay(20) would wait 20 seconds before continuing.
How can I do that in C language?
Thank you.

What is your operating system and compiler? There is no simple way in plain C, however you may utilize an API to better this.
With C in Windows, you can always include windows.h and use the Sleep(milliseconds) function, in POSIX systems it will be unistd.h and sleep(seconds).

If you are really on same platform which does not have a standard API, you can still do some experiment and based upon processor speed you can write code to do the job.
A little wild idea.
The above takes 3.2 - 3.4 seconds on my pc using codeblocks.

Maybe I would do a while loop and compare time (assuming time.h is provided on that system) - however this would be harsh on the CPU for more than a moment.
