CPP introduced the features of OOPs Concept, i.e, CPP is an object-oriented programming language which uses classes and objects for computations. OOPs is based on the principle of Polymorphism, which means, that one task can be performed in many ways.   Types of CPP Polymorphism:  Compile time polymorphism: Compile type Polymorphism is a result of … Read more

The process of defining a class by some other class as any entity reference is termed as aggregation in CPP programming. In other words, aggregation can be defined as the process of reusing a class in a form of association.
