How to Emulate The “super” Keyword In C++ 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++.

How do you call a super class constructor in C++?
