Contrived Constructor Example

class B1 {

public:

B1(int i); // constructor that takes an integer

};

class B2 {

public:

B2(int i); // constructor that takes an integer

};

class D : B1, B2 {

private:

B1 b;

int c;

public:

D(int a); // constructor that takes an integer

};

D::D(int a) : B2(a+1), B1(a+2), c(a+3), b(a+4)

{ /* … */ }

D d(10);
