Well, getch() will do it, but it's not in the standard so its considered a bad practice.

It depends on the key you want to react to and what your platform is.
getch() probably won't work if you are looking for shift/alt/ctrl/caps lock keys because those
keys are not passed to the user application by the OS.
For other keys, it depends on the platform.
For unix, for example, you can turn off line buffering on stdin via termios.

getline() by definition will read characters until it encounters a newline (ENTER).

press?

Well, how convenient that the very first example I gave in the link is for the Windows platform.
Good luck!
