C sleep function not working

Question

When including the sleep function from unistd.h the program hangs indefinitely:

#include 
#include 

int main()
{         


        

Answer 1

Are you on a Windows computer? If so, include in your program, and to pause the program, write

Sleep(time_in_milliseconds)

where in your case time_in_milliseconds should be 2000.

On the other hand, if you're on a UNIX based computer, the code looks fine (no need for ).
