Base class constructor variables

Hi how should I go about coding it if I wish to pass in variables to my base class constructor?
Initializer lists.
class Base{ int myInt;public: Base(int A) : myInt(A) {}};class Bar : public Base{public: Bar() : Base(10) {}};
Just to note:
This is valid syntax, it creates an anonymous Base instance with the value ten passed to its constructor. An example where you might use this syntax is adding value objects to a container, like so:
class Bar{ // ... Bar() { Base(10); } // ...};This is valid syntax, it creates an anonymous Base instance with the value ten passed to its constructor. An example where you might use this syntax is adding value objects to a container, like so:
std::vector<Sphere> spheres;spheres.push_back(Sphere(radius));This topic is closed to new replies.
