What is taxonomy in c plus plus?

Answer 1

Taxonomy is just another word for class hierarchy. E.g., an animal class can serve as a base class for both mammals and reptiles, while the mammal class can then be a base class for both dogs and apes, and so on. In other words, it is a method of classifying and organising your classes such that common properties are percolated up into generic base classes, reducing the need to duplicate code.
