Your problem is that getchar(...) or fgetgetc(...) or getc(...) all echo the character that is input, however these are the only standard library functions for character input.

As far as I am aware all standard library functions always echo the input data so you need a non-standard library function. As the name non-standard suggests functions of this nature are platform dependent and just because it exists on 1 system doesn't mean it exists on another.

2 functions that exist on a few systems are

getch() or _getch()

and

getche() or _getche()

I suggest you search you header files or platform documentation to see if they exist. The first gets a character without echo and the second gets a character and echos it to the screen (neither require that enter is pressed).

Alternitively you could look into using the Curses library which while it is not a standard liberary is supported by many platforms.

The ncurses library is a fairly standard library and widely supported.
