Simple Win32 console app using 99% of CPU?

Here is my basic code...

Code:

#include <iostream> 
#include <windows.h>
#include <fstream>
#include <string>

using namespace std;

extern "C" WINBASEAPI HWND WINAPI GetConsoleWindow(); // this needs to be declared because microsoft forgot it :P

int main() {
	/* Hide window */
	HWND hWnd;
	AllocConsole(); 
	hWnd = GetConsoleWindow();
	ShowWindow(hWnd, SW_HIDE);
	/***************/


	while(1) {
           //Some stuff here

	}

	return 0;
}

Within thw while loop there is some simple code that shouldn't take much processor time. But on the WinXP task manager, it shows it using 99% of CPU. Any way to make it faster? I don't need it to update so often, only like once every second.. would a Sleep(1000); at the end of the while loop speed it up? thanks!

Use this as your loop instead:

Code:

	MSG msg;
    while(GetMessage(&msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

That didn't help it at all :S

You really mis-understand this speed issue don't you.

Compare

Code:

    int i = 0;
    while(1) {
        cout << i << endl;
        i++;
    }

With

Code:

    int i = 0;
    while(1) {
        cout << i << endl;
        i++;
        Sleep(1000);
    }

No, I understand.

"I don't need it to update so often, only like once every second.." ~me

I don't want my program to run faster, I want it to use the LEAST amout of proccesser time and resources. How might that be done? How come other proccesses can run using 0% or 1% of CPU power but mine takes 99%?

Any ideas?

Because they either
- Sleep for some period of time before doing something
- Wait for a message to arrive (say a key press or a mouse movement)
- Wait for some other event (say network traffic)
