There might a be slight memory overhead (due to padding) when using inheritance compared to copy and past, consider the following class definitions: struct A . The order of derivation is relevant only to determine the order of default initialization by constructors and cleanup by destructors.

The class who is going to provide its features to another. Hybrid inheritance is performed when we have to mix different. Programming FundamentalsTable of Contents1.
