I have been asked to add a pause to an existing C++ program.
They do not want to use the Windows builtin scheduler for reasons they won't share with me.
Is the correct way of doing this something like:-
void Sleep(10000);

NOPE. . .
your teacher doesnt want you to use

system Commands

system("pause");

Try using

 
cin.get()

or

#include "conio.h" 

 _getch();   

but its much better to you cin.get();

have a look at this post

Hope this helps

I am afraid that my question was not clear enough.
We need the program to stop running for a period of time and when that time has elapsed carry on running.
That was why I suggested sleep().

DON'T use:

include <windows.h>

Sleep(5000);

A nice explanation as to why would be nice.

sleep is resource heavy, it calls into the system( i think) or at least a wrapper for it. Otherwords, it is not standard c++ .this is the best way i know how to do this :

#include <ctime>

void timer(double seconds)
{
clock_t x;
x=clock()+seconds*CLOCKS_PER_SEC;
while(clock()<x){}
}

[codefreak.]

int count = 1;

while (count <= 1000)
	count++;

what?
listen what you're saying ..
1) Sleep is just pausing current thread, this means it uses maximumly 1% of processor while your code tries to execute so fast as it can.. making processor 100%

Sleep doesnt have anything to do with system(), i think you have gotten somewhere wrong, the most inefficient way to sleep is just exact way you showed.

What I used to do to temporarily pause it was just input a character with the same kind of message it would give you from a Microsoft compiler:

char pause()
{
	char c;
	cout << "\nPlease press a button and then hit <Enter>: ";
	cin >> c;

	//return the character pressed incase it is useful:
	return c;
}

oh my bad, sorry im not used to using it. But i know that sleep() is ok, but Sleep() is alright too but it is not standard c++
