1. Conio H C
2. #include Conio.h In C++

Jul 19, 2017 ‘conio.h' is included in MSDOS compilers but not in gcc/g. Hence, you cannot include conio.h in DevC. But still there are certain substitute which may be considered in place of conio.h. For further information you may refer the following post: CONIO.H alternative for Dev-C IDE Users. But in my opinion you should not use conio.h or it's alternatives. It may create portability problems. The conio.h header file used in C programming language contains functions for console input/output. Some of its most commonly used functions are clrscr, getch, getche, kbhit etc. They can be used to clear screen, change color of text and background, move text, check whether a key is pressed or not and to perform other tasks.

conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output.^[1] It is not part of the C standard library or ISO C, nor it is defined by POSIX.

This header declares several useful library functions for performing 'console input and output' from a program. Most C compilers that target DOS, Windows 3.x, Phar Lap, DOSX, OS/2, or Win32^[2] have this header and supply the associated library functions in the default C library. Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions. Some embedded systems or cc65 use a conio-compatible library.^[3]

The library functions declared by conio.h vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to the first few DOSINT 21H functions. The library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls. This library also has additional functions inspired from the successful Turbo Pascal one.

Compilers that target non-DOS operating systems, such as Linux or OS/2, provide similar solutions; the unix-related curses library is very common here. Another example is SyncTERM's ciolib. The version of conio.h done by DJ Delorie for the GO32 extender is particularly extensive.^[4]
