You are encouraged to solve this task according to the task description, using any language you may know.
Write a program that does the following in this order:
- Input an amount of time to sleep in whatever units are most natural for your language (milliseconds, seconds, ticks, etc.). This unit should be noted in comments or in a description.
- Print "Sleeping..."
- Sleep the main thread for the given amount of time.
- Print "Awake!"
- End.
Ada
The Ada delay statement takes an argument of type Duration, which is a real number counting the number of seconds to delay. Thus, 2.0 will delay 2.0 seconds, while 0.001 will delay 0.001 seconds.
<ada>with Ada.Text_Io; use Ada.Text_Io; with Ada.Float_Text_Io; use Ada.Float_Text_Io;
procedure Sleep is
In_Val : Float;
begin
Get(In_Val); Put_Line("Sleeping..."); delay Duration(In_Val); Put_Line("Awake!");
end Sleep;</ada>
BASIC
<qbasic>INPUT sec 'the SLEEP command takes seconds PRINT "Sleeping..." SLEEP sec PRINT "Awake!"</qbasic> "SLEEP" with no argument will sleep until a button is pressed on the keyboard (including modifier keys such as shift or control). Also, pressing a key while SLEEP is waiting for a specific amount of time (as above) will end the SLEEP.
C++
<cpp>#include <unistd.h>
- include <iostream>
using namespace std;
int main(int argc, char* argv[]) {
useconds_t microseconds; cin >> microseconds; cout << "Sleeping..." << endl; usleep(microseconds); cout << "Awake!" << endl; return 0;
}</cpp>
Java
<java>import java.util.Scanner;
public class Sleep{ public static void main(String[] args) throws InterruptedException{ Scanner input = new Scanner(System.in); int ms = input.nextInt(); //Java's sleep method accepts milliseconds System.out.println("Sleeping..."); Thread.sleep(ms); System.out.println("Awake!"); } }</java>
Toka
This makes use of the sleep() function from libc which suspends execution for a specified number of seconds.
