Automatic Memory Management

Consider the following declarations.

Department qc("Qualitiy Control", Employee("Tester, Tina", 50000));
Department dept("Shipping", Employee("Hacker, Harry", 35000));

Suppose we assign one department to the other.
```
dept = qc;
```
This assignment causes a memory leak! (See following slide).
When one object goes out of scope (and the other doesn't) the Employee is destroyed, causing a dangling pointer.
