C++ :Show percentage done

[WhoknowsmeaUdiO]

Hello there, I haven't got any programming expierence aside from AS2 and I've started out with C++ 2 days ago.

Yes, I used the search.

What I'm trying to do, is show: "78% done", with the percentage increasing. Now, I know how to do this, but I do not know how to make it NOT start a new line everytime.
I know how to do:

1% done
2% done
3% done

etc....

I want to do:

1% done

But with 1 % increasing every x milliseconds (not necessarily actually something loading) and staying on one line.

I hope that someone can help me and that I did not explain too vaguely.

system("cls") ?

Thanks, but is there also a way to just delete a certain line, I'd prefer that.

Well, you could copy everything you have in the console, remove the last line, clear screen and then print

So no automatic way. Anyways, thx.

You need to move the cursor back to the position where you printed the percentage
On windows, you use SetConsoleCursorPosition from Win32 (console api reference here)
On Unix you need to use curses or ncurses

And don't use clearscreen, as that will make the screen flicker
if you must use clearscreen, do it in a seperate backbuffer (page)

Conclusion, stdout sucks. Stick to the real console api instead. And please, avoid system at all costs.

There is no "standard" way of doing this sort of thing in C/C++. The way you will end up doing it depends entirely on what compiler you use and what OS you're writing the program for. Are you doing this on Linux, Windows, Mac, DOS? What compiler are you using?
