C# is a general-purpose programming language developed by Microsoft. Method overriding is a technique by which a method in the parent class is redefined or overridden in the child class. Creating a method in the derived class with the same signature as a method in the base class is called as method overriding, It is called the compile time polymorphism, It has the same method name but with different signatures or the parameters. While it is used to grant the specific implementation of the method which is already provided by its parent class or super class. Overloading and Overriding, Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. If we use Virtual keyword, then we tell to compiler that this method can be overridden by the derived classes. Method overloading is also called  early binding or compile time polymorphism or static binding. Increment operator, constructor and new and delete can be overloaded. We have two classes : parent class Shape and child class C… In overriding, function signatures must be same. When the derived class needs a method with the same signature as in the base class, but wants to execute different code than the one provided by the base class then method overriding will be used.
