Computer Display Modes
Computer display is categorized in text and graphics modes.
So far, in the previous chapters after running the program in C++, we get the result on the screen in the form of characters. The mode in which the computer display represents the contents of the screen in terms of characters is called text mode.
In most of the computer applications, information is conveyed in the form of pictures/images. In numerous applications such as CAD/CAM, image processing, and multimedia, we would like to have pictorial or image information on the screen. In such a case, one needs to set the computer screen in graphics mode. In this mode, the screen consists of pixels. Fine/small dots on the screen are drawn in the form of pixels. Pixels are arranged in rows and columns, and they can be illuminated.
