Right now, I have a console application I m working on, which is supposed to display and update information to the console at a given interval. The problem I m having is that with a carriage return, I can only update one line of text at a time. If I use a newline, the old line can no longer be updated using a carriage return.
What can I do here?
You might be able to find a curses library variant that works on your platform.
The correct answer is to use the curses library as mentioned by Mark. But if you re on Unix-like systems and can t be bothered with curses then the quick and dirty solution is to directly print out vt100 escape sequences:

I often do this especially in scripting languages that doesn t have a curses binding.
This is a really ugly solution, but in a pinch you could always just clear the console entirely and then reprint everything. This strategy looks a bit ugly in some cases; it may make things look blinky.
