Answer 2

Line 20: Constructor must have same name as class, make it uppercase -> Characteristic(){}
Line 33, 45, 50: Here you want to access the class, and your classes name is uppercase again -> Characteristic
Line 50: Characteristic's constructor takes a <string> as an argument, so LeaveMeAlone needs to be in double quotation marks so compiler recognizes it as a string -> "LeaveMeAlone"
Line 50: Missing semicolon at the end of the line!
