Derived Class Reference to Base Pointer

[vwbora]

Hi,

Can you please tell me how I can obtain a pointer to a base class from
a variable which is a reference to a derived class.

As an example, I have a variable which is a reference to a derived
class (Manager)and I want obtain a pointer to the base class
(Employee).

Thank you for help.

Pete
class Employee
{
char* name;
int age;
int department;
int salary;

public:
Employee(char* name);
void print();
};
class Manager : public Employee
{
EmployeeList employees;

public:
Manager(char* name, Employee* people);
void print();
};

{ .... };
class Manager : public Employee
{ .... };

Just use the unary & operator, which returns a pointer to the object
on its right. The conversion from a derived class pointer to a base
class pointer will happen automatically.

void foo( Manager& m )
{
Employee* e = & m;
}
