hers a function that Ive used before:
| Code: | void ClearScreen()
{
HANDLE hSTD = GetStdHandle(STD_OUTPUT_HANDLE);
COORD coordinates = {0,0};
CONSOLE_SCREEN_BUFFER_INFO buffer_info;
GetConsoleScreenBufferInfo(hSTD, &buffer_info);
FillConsoleOutputCharacter(hSTD, ' ', buffer_info.dwSize.X * buffer_info.dwSize.Y, coordinates, NULL);
SetConsoleCursorPosition(hSTD, coordinates);
} |
I've had it sitting in a folder for so long I cant remember if I wrote it or someone else did...
as for the loop, you could either use a timer or you could use a timer and just sleep but if you go for the latter, you might wanna do it in a different thread (I dunno, depends on what you want).

| Can't you use System("cls");? I don't know much C++, I remember when I used System it was like batch... System("echo ..."); and System("Pause"); so I guess cls will work too.

What do you want it to do?
If it does nothing
| Code: |
for ( ; ; ) //never ending
{
Sleep(1000); //pause for a second--I think that's how you do it
}

Use a while statement instead of an endless for loop. Have the condition a toggled boolean or something of the sort so it has an escape method and doesn't just get stuck in memory. (Just a suggestion.)
@Sam: Yea you can use System("cls") most don't use the System() command though due to overhead and sloppy methods. If you google pros and cons of System() you should find some interesting reads about how it creates a lot of overhead for simple tasks such as cls.

| I think you need to include "dos" or "dos.h"... and try sleep, maybe its case sensetive.
