CONIO.H

The <conio.h> (console input/output) header file in C is an older, non-standard library that was originally developed for MS-DOS compilers, such as Turbo C. It provides functions for handling console-based input and output, as well as performing screen manipulation tasks. Some of the most commonly used functions in <conio.h> include getch(), which reads a single character from the keyboard without echoing it to the screen, and clrscr(), which clears the console screen. Other functions, such as gotoxy() for moving the cursor to specific coordinates and textcolor() for changing text color, are also part of this library. However, <conio.h> is not part of the C standard library, and it is not supported by many modern compilers, particularly those that target UNIX-based systems (like Linux and macOS). As a result, its use is generally discouraged in favor of more portable and standardized libraries, such as stdio.h and platform-specific libraries that handle console I/O in a more flexible and cross-platform way.
