Base class constructors are automatically called for you if they have no argument. If you want to call a superclass constructor with an argument, you must use the subclass's constructor initialization list. Unlike Java, C++ supports multiple inheritance (for better or worse), so the base class must be referred to by name, rather than "super()".
class SuperClass{ public: SuperClass(int foo) { // do something with foo }};class SubClass : public SuperClass{ public: SubClass(int foo, int bar) : SuperClass(foo) // Call the superclass constructor in the subclass' initialization list. { // do something with bar }};More info on the constructor's initialization list here and here.
