Console I/O
Console I/O (Input/Output) is a fundamental programming concept that involves reading data from and writing data to a console or terminal interface. It enables interaction between a program and a user or system through text-based input (e.g., keyboard) and output (e.g., screen). This is commonly used for debugging, command-line applications, and simple user interfaces in various programming languages.
Developers should learn Console I/O for building command-line tools, scripts, and applications that require user interaction or data logging, such as utilities, automation scripts, and educational programs. It is essential for debugging by printing variable values and for creating basic interfaces in languages like Python, Java, and C++ where graphical interfaces are not needed.
