Inheritance by Example Inheritance in C++ is accomplished using the : operator. Continuing with the Number and ImaginaryNumber example used above, consider the following code sample. Run this code class Number { public: Number() = default; Number( Number const& ) = default; virtual ~Number(...
If virtual inheritance is used, the base class is referred to as a virtual base class. Multiple base classes can be specified, separated by commas. If a single base class is specified, the inheritance model is [Single inheritance](../cpp/single-inheritance.md).If more than one base class...
