Class members that are objects - Pointers or not? C++

Question

If I create a class MyClass and it has some private member say MyOtherClass, is it better to make MyOtherClass a pointer or not? What does it mean also to have it as not a

Answer 1

I follow the following rule: if the member object lives and dies with the encapsulating object, do not use pointers. You will need a pointer if the member object has to outlive the encapsulating object for some reason. Depends on the task at hand.

Usually you use a pointer if the member object is given to you and not created by you. Then you usually don't have to destroy it either.
