I want to partition the output screen into two parts (just like frames do it in HTML). So that one part may remain fixed and display some content which is updated based on input received from the other part.
I do not wish to venture into GUI stuff therefore OpenGL, SDL etc are ruled out (I wish to do it in command line mode). I have Borland C++ with graphics.h support, but it is just too old to carry on.
What alternatives do I have at my disposal (If not C++, a solution in C will also be Ok.)
You may want to take a look at curses-like libraries like PDCurses.
Other than that, you may use ANSI terminal escape sequences to control the cursor on a text window, this may be quicker if what you are doing is simple, otherwise use PDCurses and it will handle the escape sequences for you.
