hi,

i am having a project where i must implement a method that takes measurements(random numbers) on specific time intervals.This means that i should read (for example) a number every 5minites...I ve been told for a sleep function but i can't find any info about it....Any thoughts on how i should implement this method?:confused:

also is there any way to read the system time through c++?{to know what time appears in the system clock}

thanks in advance for your help....:)

If you are using Linux, then this for sleep and if you are using windows then this.

also is there any way to read the system time through c++?{to know what time appears in the system clock}

Yes there is, use the header file #include <ctime> if using C++ or #include <time.h> if using C. For the header reference see here and here.

thanks in advance for your help....Nicolas

Glad we could help.

so i shoud implement that function as thread?{In order to call the sleep function on that thread....}

No need to complicate matters, here is a simple way of using the function..

#include <iostream>
#include <windows.h>
using namespace std;
 
int main(int argc, char** argv)
{
    cout << "Hello" << endl ;
    cout << "Wait for 3 seconds..." << endl ;
    Sleep(5000) ; // takes the time in milliseconds ( 1 second = 1000 milliseconds)
    cout << "World" ;
    getchar( ) ;
    return 0 ;
}
