Re: Weird behaviour of private attribute + overloaded method

It outputs 'bool(false)', while I expect it to print 'int(123)'.

Foo::id is private so Bar::setId() cannot use it. It uses an implicit public Bar::id (different from Foo::id). Foo::getId() correctly read the private attribute Foo::id (not the public Bar::id) and return it.

Am I missing something and this is really expected behaviour ?

I think it is. - if we allow Bar::setId() to change Foo::id, "private" keyword is useless - if we allow Foo::getId() to read Bar::id instead of Foo:id, then a derived class can pertubate private things in the mother class (which is not a good solution). -- Eric Daspet
