Replacing stuff after being written on screen

[Naforce]

Hi!
I' fairly new to all this programming, so my question might be stupid, but still, I need an answer =)

I want to replace a single row on the screen, like this.

#include <iostream>
#include "windows.h"

using namespace std;

void main(void)
{
cout << "Loading..." << endl;
for(int x=0;x<20;x++)
{
cout << "|" << endl;
Sleep(70);
REPLACE "|" with "/";
Sleep(70);
REPLACE "/" with "--";
Sleep(70);
Replace "--" with "\\";
Sleep(70);
}
}

I need to know how to replace the symbols but not system("cls") since i still want it to say "Loading..." =) Grateful for any help!

No Spoonfeeding per the Posting Guidelines - maybe an algorithm would help more?

By way of explanation
The '\x8' character is backspace and should work on most text based applications on most operating systems.
If you want to do anything trickier than that, then you're probably going to have to specify a platform specific question because Win32 and Unix consoles are very different.

Remember, the console comes from the old days when it was a typewriter/printer.

You can put in a new paper and you can type lines but you cannot backup or randomly jump anywhere on the paper.

You could clear the screen and replace "Loading"..." each time".

More than that and you need a graphical program. In this case, a WIn32 application that implements a progress bar.

Back in the MSDOS days, the memory at 0xA000 would hold the values of the screen. So it was possible to mess with the screen writing directly to this segment (AKA Video Memory).

I think it was also possible to write directly to the screen using the software interrupt 0x10, again when using MSDOS. This way you could alter any character at any position.

I havent tried this for years, so I dont know if coding either of these options would work on modern OSes (like XP or VISTA).
