Inheritance Inheritance allows one class to inherit properties and methods from another class. It helps with: Code reuse Cleaner structure Reducing duplication class Parent { public void Show() { Console.WriteLine("Parent class method"); } } class Child : Parent { public void Display() { Console.WriteLine("Child class method"); } } Child obj = new Child(); obj.Show(); // Inherited from Parent obj.Display(); // Child’s own method Child : Parent ? Child inherits Parent. Child automatically gets access to Parent’s public methods. Polymorphism Polymorphism means "many forms." A method can behave differently depending on how it is used. In C#, there are two main types: Compile-time Polymorphism (Method Overloading) Run-time Polymorphism (Method Overriding) Method Overloading (Compile-Time) Same method name, but different parameters. class Calculator { public int Add(int a, int b) { return a + b; } public int Add(int a, int b, int c) { return a + b + c; } } The method name is the same ( Add ) Parameters are different The compiler decides which one to call Method Overriding (Run-Time) A child class changes the behavior of a parent class method. class Animal { public virtual void Sound() { Console.WriteLine("Animal makes sound"); } } class Dog : Animal { public override void Sound() { Console.WriteLine("Dog barks"); } } Animal obj = new Dog(); obj.Sound(); Output: Dog barks virtual ? Allows the method to be overridden override ? Replaces the base method The decision happens at runtime
