Method Overriding is a type of polymorphism.

In Polymorphism, poly means Many and morph means Forms. Polymorphism is one of the main pillars in Object Oriented Programming.

. Only abstract or virtual method can be overridden.

So, here it is clear that we can modify the base class methods in derived classes. MongoDB, Mongo and the leaf logo are the registered trademarks of MongoDB, Inc.

It has several names like Compile Time Polymorphism or Static Polymorphism and sometimes it is called Early Binding.

It permits a class, struct, or interface to declare multiple methods with the same name with unique signatures. Whencontrolpassesoverthe;,itimmediatelydestroysthetemporary.

Method Overloading means creating multiple methods in a class with same names but different signatures (Parameters). And the passing values are negative then it asks for new value. Compiler automatically calls required method to check number of parameters and their type which are passed into that method. public:

But when you call the ChildClass Add method with less than zero value then it checks for negative value.
