Deallocating Dynamic Memory

When you make a variable of a certain type, the object is allocated on the run-time stack. This object automatically goes away when the program leaves the block in which the variable is allocated:
```
void f()
{
   Employee harry; // memory for employee allocated on the stack
   . . . 

} // memory for employee object automatically reclaimed
```

Value that are allocated on the heap do not follow this automatic allocation mechanism. You must reclaim the memory using the delete operator.

void g()
{
   Employee* boss;
   boss = new Employee(. . .);
      // memory for employee object allocated on the heap
   . . .
   delete boss; // memory for employee object manually reclaimed
} // memory for boss automatically reclaimed
