Question

Which type of inheritance leads to diamond problem?

(a) Single level

(b) Multi-level

(c) Multiple

(d) Hierarchical

I have been asked this question during an interview.

Origin of the question is Inheritance topic in portion Inheritance & its Types of Object Oriented Programming

Answer 1

The correct answer is (c) Multiple

Best explanation: When 2 or more classes inherit the same class using multiple inheritance and then one more class inherits those two base classes, we get a diamond like structure. Here, ambiguity arises when same function gets derived into 2 base classes and finally to 3rd level class because same name functions are being inherited.
