If so, my theory is probably wrong.

I must admit thyat I don't know enough about the C++ function you
called to tell how should it work.  Can someone who knows that please
tell?

No, conio's getch is DOS-specific; it uses a certain system call
which always works  by single characters.

To write more portable code, which uses standard functions, you need
to call the tcsetattr function with the ICANON bit reset in the
c_lflag member of its last argument (which is a structure).  After
that, any input function that you call will return after a single
character has been read from the terminal.
