Input "Number of cars=", A
Is it possible that after "number of cars=" I get like not an EMPTY screen places but rather already an number like "12", and IF i want to change this number I will. and simply press the enter.
Number of cars= _ (nothing filled)
BUT like this: Number of cars = 12 (already into the input)
(press enter and i get 12, or i change it to lets say only 2.
