Another Constructor Example

private:

float real, imaginary;

public:

complex(float real);

complex(float real, float imaginary);

};

complex a; // error

complex b(5.0); // ok

complex c(1.3, 3.5); // ok

complex d(2); // danger will robinson! if complex(int) is

// added in the future, this code can change!

complex *d, *e, *f; // This is okay because these are

// only pointers, not instances!

d = new complex(5.4); // ok

e = new complex(4.2, 5.6); // ok

f = new complex; // error
