What is Ncurses
Ncurses is a programming library that provides a set of functions to facilitate the development of text-based user interfaces in a terminal-independent manner. It is commonly used in Linux and Unix systems to create console-based applications that can be run in a terminal window.
Ncurses provides an abstraction layer that allows developers to write text-based user interfaces without worrying about the underlying terminal hardware or software. This makes it possible to create applications that can run on any terminal, regardless of its capabilities or limitations.
The library provides functions to manipulate text, colors, and windows, as well as input and output functions to handle user input and display output on the screen. It also includes support for mouse input and resizing terminal windows.
Ncurses has been widely used in a variety of applications, including text editors, file managers, and system administration tools. It is also used in many popular console-based applications, such as the Lynx web browser and the Midnight Commander file manager.
Overall, Ncurses is a powerful and flexible library that enables developers to create text-based user interfaces that are portable and can be run on any terminal. It is an essential tool for anyone interested in developing console-based applications on Linux and Unix systems.
