Answer Explanations:
1. Class members are private by default, while struct members are public by default
2. Copy constructor takes const reference to avoid infinite recursion and unnecessary copying
3. Static members belong to the class itself, not individual instances, shared among all objects
4. deque (double-ended queue) allows efficient insertion/deletion at both front and back
5. Only difference between struct and class is default access: public for struct, private for class
6. sizeof operator cannot be overloaded as it's resolved at compile time
7. const member functions promise not to modify the object's state (non-mutable members)
8. vector header file is required to use std::vector container class
9. Compiler automatically generates default constructor if no constructors are explicitly defined
10. Friend functions can access private and protected members despite not being class members
