Ruby Language File and I/O Operations get a single char of input
Example
Unlike gets.chomp this will not wait for a newline.
First part of the stdlib must be included
require 'io/console'
Then a helper method can be written:
def get_char
input = STDIN.getch
control_c_code = "\u0003"
exit(1) if input == control_c_code
input
end
Its' imporant to exit if control+c is pressed.
