The diamond problem occurs due to _______ and can be resolved using _______. 

  • inheritance, interfaces 
  • encapsulation, templates 
  • multiple inheritance, virtual inheritance 
  • overloading, namespaces
The diamond problem is a complication that arises from multiple inheritance when two classes B and C inherit from A, and class D inherits from both B and C. If there is a method in A that B and C have overridden, and D does not override it, then which version of the method does D inherit: that of B, or that of C? This ambiguity can be resolved in C++ using virtual inheritance, ensuring that only one instance of the base class exists in the derived class.
