Answer 1

There is a way to do it...but it uses getche() (or getch()) from the non-standard <conio.h> header file.
Bare in mind I'm an amateur and just "playing around" in programming and don't understand the implications of using non-standard c/c++ header files.
I've had a go and did get it to work in my IDE..
