8.10 Updating the Terminal

As written in the overview, ncurses windows are images in memory. This means that any change to a window is not printed to the physical screen until a refresh is done. This optimizes the output to the screen because you can do a lot of manipulations and then, once, call refresh to print it to screen. Otherwise, every change would be printed to the terminal and decrease the performance of your programs.
