How to update a printed message in terminal without reprinting

I want to make a progress bar for my terminal application that would work something like:

 [XXXXXXX       ] 

which would give a visual indication of how much time there is left before the process completes.

I know I can do something like printing more and more X's by adding them to the string and then simply printf, but that would look like:

 [XXXXXXX       ] 
 [XXXXXXXX      ] 
 [XXXXXXXXX     ] 
 [XXXXXXXXXX    ] 

or something like that (obviously you can play with the spacing.) But this is not visually aesthetic. Is there a way to update the printed text in a terminal with new text without reprinting? This is all under linux, c++.
