DANGLING-ELSE PROBLEM
Whenifandif-elseareusedtogether,andthesourcecodeisnotproperlyindented,it
can be difficult to determine which if associates with the else. For example:
if (car.door.isOpen())
if (car.key.isPresent())
car.start();
else car.door.open();
Didthedeveloperintendfortheelsetomatchtheinnerif,butimproperlyformatted
the code to make it appear otherwise? For example:
if (car.door.isOpen())
if (car.key.isPresent())
car.start();
