// Constructor dynamically allocates space for the
// first and last name and uses strcpy to copy
// the first and last names into the object.
Employee::Employee( const char *first, const char *last )
{
   firstName = new char[ strlen( first ) + 1 ];
   assert( firstName != 0 ); // terminate if not allocated
   strcpy( firstName, first );

   lastName = new char[ strlen( last ) + 1 ];
   assert( lastName != 0 );  // terminate if not allocated
   strcpy( lastName, last );
}

// Output employee name
void Employee::print() const
   { cout << firstName << ' ' << lastName; }

// Destructor deallocates dynamically allocated memory
Employee::~Employee()
{
   delete [] firstName;   // reclaim dynamic memory
   delete [] lastName;    // reclaim dynamic memory
