How to realize a getch function in standard C/C++

[Shugong Wang]

getch() function is not a standard C/C++ function. Thought gcc provieds
ncurses.h and a getch() function is realized, I still want to know how to
realize a getch() function in standard c or c++.

There is no standard way of doing this in C or C++. The only proper method
is to use is third-party libraries, such as ncurses or pdcurses.

You might be able to use getchar(), or retrieve a character from cin, but
that's about it for the standard.
