5. Which type of inheritance is not supported directly by C++? a) Single inheritance b) Multiple inheritance c) Multilevel inheritance d) Hybrid inheritance

Answer:

In C++, all the mentioned types of inheritance are supported directly. However, the question likely refers to the term "directly" being misinterpreted.

1. Single Inheritance: This is where a class is derived from one base class. C++ supports it directly.

2. Multiple Inheritance: This is where a class can inherit from more than one base class. C++ supports this directly, but it can lead to ambiguity issues (like the diamond problem).

3. Multilevel Inheritance: This involves a class being derived from another derived class. C++ also supports this directly.

4. Hybrid Inheritance: This is a combination of more than one type of inheritance. While C++ supports this, it can require careful management of complexities that arise, particularly with multiple inheritance scenarios.

Summary:

Thus, if the question is about which type is "not directly" supported, none of them fall into that category as C++ supports all these types of inheritance to varying degrees. Therefore, the best answer is that all types are supported, but complexities arise primarily in hybrid and multiple inheritance scenarios. If you must choose based on common misconceptions, multiple inheritance could be seen as the "least direct" due to potential complications.

Final Answer:

None of the options (a, b, c, d) represent a type of inheritance that is not supported directly by C++.
