And C++ doesn’t have a super or base keyword to designate “the base class” , like C# and Java do. One reason for this is that C++ supports multiple inheritance, which would make such a keyword ambiguous. But on the other hand, multiple inheritance is not used so often in C++.26 Ara 2017

super means, calling the last implementor of a method (not base method) base means, choosing which class is default base in multiple inheritance.
Read moreHow do you call a base class constructor?
A derived Java class can call a constructor in its base class using the super keyword . In fact, a constructor in the derived class must call the super’s constructor unless default constructors are in place for both classes.
Read moreWhat happens when there is no default constructor?
If no user-defined constructor exists for a class A and one is needed, the compiler implicitly declares a default parameterless constructor A::A() . This constructor is an inline public member of its class.
Read moreDoes base class need a default constructor?
A derived class can only be constructed once all base class’ are fully constructed. So it doesn’t matter if you call the base class’ constructor or not . If you don’t call, as long as there is a default constructor available for compiler to determine, it will be called. Otherwise compiler will throw error.
Read moreCan a class have no default constructor?
Not having a default constructor is no problem, as long as you don’t use one . Always specifying an argument at construction is ok, when there is no obvious default argument.11 Kas 2011
