Re: [Dev-C++] simle formatting

Assuming that you need the x coordinate of the left most character in the
string you need to output then the formula is fairly simple.

left_coord = (area_width - text_width) / 2

Area_width meaning the width of whatever you are trying to center the text
into. The formular is the same weather you are using console mode text, or
pixels in a window. If you want to center verticaly then just use height
values instead.

If you don't understand why this works then just ask and I will explain it.

It depends upon what environment you are working in as to how to clear the
screen. In a console you could just scroll the entire area off view,
althought there may be a dedicated function that clears the screen but I
don't know it. Anyone else? If you are working in OpenGL or DirectX then
there is probably a function to do it, but I don't know much about them so
you should refer to the documentation if necessary.
