100. Constructors-II

Question.6

A driver class holds a reference to a shared bus:

class SensorDriver {
   I2C_Bus& bus;
public:
   SensorDriver(I2C_Bus& b) : bus(b) {}
};

Can bus be initialized in the constructor body instead of the initializer list?

Need Help? Refer to the Quick Guide below

Yes -- references can be assigned in the body
No -- references must be initialized at creation; the initializer list is the only valid place
Yes -- but only if the reference is mutable
No -- references cannot be class members
