How can the diamond problem be resolved in C++?

Correct option is B

The diamond problem in C++ is resolved using virtual inheritance, which ensures that the derived class receives a single instance of the base class, avoiding ambiguity caused by multiple inheritance paths.
Important Key Points:
1. The diamond problem arises when a class inherits from two classes that share a common base class, leading to ambiguity in resolving which base class method or property to access.
2. Virtual inheritance eliminates the duplication of the base class, ensuring only a single instance is inherited by the derived class.
3. Syntax for virtual inheritance:

Knowledge Booster:
· Function overloading: Resolves ambiguity between functions with the same name but different parameters, not the diamond problem.
· Single inheritance: Avoids the diamond problem but limits inheritance to a single parent class, which is less flexible.
· Templates: Used for generic programming but do not address the diamond problem.
· Avoiding constructors: Irrelevant, as constructors cannot resolve inheritance ambiguities.
