Hey I was wondering how I would align my text on a C++ console application. I belive console applications can only have a width of 800px so I figure there must be some sort of implemented alignment system. Really I want to display some numbers on the same line on the right and some on the left. Thanks

Solution 2

calculate the length of your display area. (DispLen)
calculate the length of your text. (TextLen)
LeftMargin = DispLen - TextLen;

now add white space LeftMargin times before your text then print.

Hope it helps.

Solution 1

0) The font used in a console window must be a non-proportional font. This is the default selection, and most end-users don't even knowmthey can change the font, much less how to do it.

1) If you want to right-align numeric values, you have to convert the number to a string, and pad the left side of the string with a sufficient number of spaces. Look at the various options available for the sprintf function. (Left-alignment is accomplished the same way, only you're padding the number on the right.

Actually printf format specifiers allows directly number alignment (and you can do the same with std::cout).

@CPallini - thta's why I said look at the sprintf method. It allows you to do all of that with the correct formatting specifiers.
