Move text cursor to particular screen coordinate?

Neither C nor C++ have any notion of a screen or console; they only see streams of bytes, which have no inherent display characteristics. There are a number of third-party APIs like ncurses to help you do that.

If you want a quick-n-dirty solution and the terminal you're working with understands ANSI escape sequences, then you can do things like

printf("\033[%d;%dH", row, col);

to move the cursor to a specific row and column (where the top left corner is {1,1}). You'd be better off using ncurses, though (or the equivalent for your platform).

Use SetConsoleCursorPosition.

There are a bunch of other functions in the same part of the MSDN library. Some of them may be useful too.
