• Virtual functions in C++ allow dynamic binding and are overridden in derived classes

• Encapsulation is bundling data and methods that operate on the data together

• Abstraction is hiding the complex implementation details and showing only necessary features

Friend function is a function that is not a member of a class but has access to its private and protected members. Getter setter are methods used to access and modify private variables. Static variables are shared among all instances of a class. Static functions are functions that can be called without an instance of the class.

Diamond problem occurs in multiple inheritance when a class inherits from two classes that have a common base class.

• Diamond problem can be resolved using virtual inheritance in C++.

• Virtual inheritance ensures that only one instance of the common base class is inherited.

• Example: class A is inherited by classes B and C, then class D inherits from both B and C. Using virtual inheritance for B and C in D resolves the diamo
