Answer 1

First of all, conio.h is itself a file, called as 'header file'. The way you include it in your C program is called "preprocessor directive". This will just place all the function definitions in conio.h, in your program while compiling.
conio.h is used basically to clear screen (clrscr()), get characters (getch(), getche(), getchar()), print in colors (cprintf()) and text based graphics programming (like printing in colors, moving around the screen by specifying the position, etc).

Answer 2

Answer 3

Answer 4

it is a header file used in old MS-DOS compilers.we should include this header file in our program when we use the functions like clrscr(),getch() and getche.
