first code - need some explaining of logic

[korenron]

no, I have just tested it
I have press 'a' '1' 'fjdfsjsd'
only after I press "Enter" the program exit

[korenron]

I think I got it
the main code is very simple
just wait for "Enter" to be press
so this is why it's in loop
he wait for "enter" , and mwanwhile with for the button to be press

am I right?

Thanks ,
