    1. Value Semantics CS-240 & CS-341 Dick Steflik

    2. Value Semantics determine how the value(s) of one object are copied to another object in C++ the value semantics consist of the assignment operator and the copy constructor these allow assignment of one object to another and the creation of one object from another

    3. for simple/static objects the default assignment operator and copy constructor will do what is needed; i.e. a member by member copy of the elements making up the object.

    4. for dynamic objects where the private data includes dynamically allocated data (ex. dynamic array) we must overload both the default copy constructor and the default assignment operator.

    5. implementation

    6. copy constructor

    7. overload assignment operator
