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
