Capture stdin input without echoing characters to screen

I have a very simple code:

char character;    
std::cin >> character;

However, I would like it to behave as follow:

1. Don't echo to console the character I type
2. std::开发者_如何学Gocin should return (unblock) right away when a character is pressed without having to press the Enter key

Is this possible? I also have access to Qt.

This is going to be platform dependent, but you can use

getch() which is part of conio.h if you're on windows

or

getch() as part of curses.h if you're on *nix
