Do you mean frpm stdin (which others assume)? Or from the actual terminal? 
Several programs do the latter, I think passwd, sudo and su all do so.

Basically you need to open /dev/tty, but there is more to it than just that - 
eg what if there is no /dev/tty?

Reading programs that do what you want is a good way to learn.
