(C++) Dynamic Output?

So, I'm very new to C++, and was looking for a way to output variables at a given location on the home screen, something like output(x,y,'blah') which would put the word blah at column x and row y. It seems all but necessary for any homescreen game (roguelikes, for example), and using cout seems horrendously inefficient. So, anyone know a command/library that has what I need?
