Questions relating to the use of the DOS getch() function

getch() is defined in <conio.h>, a header file used mostly by MS-DOS compilers to provide console input/output.

This function is provided on Microsoft platforms, but is not in the C standard library, nor in POSIX.

It is similar to the standard library getchar(), but disables terminal echo of the character that is returned.
