class A {
A() { }
};
class B : public A {
B() : A() { }
};
Why do we need to call the base class’s constructor explicitly inside B‘s constructor? Isn’t it implicit?
class A { A() { } }; class B : public A { B()

It is implicit. You’ll need this syntax in case A has a constructor that has arguments, this is the way to pass them.
