Lifetime of created objectafter assigning dereferenced new to reference

Axel Gallus

Codeexample:

SomeObject & SO = * new SomeObject();

When exactly will the created SomeObject be removed/freed from memory?

1.) Is it when the reference SO doesn't exist any more e.g. if the reference
is created in
a method SomeObject will disappear when the method is left?

2.) Or only if delete (& SO) is called?

Regards

When you do

delete &SO;
