Lines 4–11 declare the stripped-down class SimpleCat. On line 27, Frisky is created on the stack, which causes the constructor to be called. In line 30, the SimpleCat pointed to by pRags is created on the heap; the constructor is called again. In line 33, delete is called on pRags, and the destructor is called. When the function ends, Frisky goes out of scope, and the destructor is called.
