The diamond problem in C++ represents the inability of the programming language to support hybrid inheritance using multiple and hierarchical inheritance.
Suppose we have a university with some faculty members and some graduate students. A simple inheritance scheme in this scenario might have different types of people in different roles. However, all of them inherit from the same Person class.
The Person class defines an abstract getRole() method that would then be overridden by its subclasses in order to return the correct role type. Things up till this point is simple, however, if we wish to model the role of a TA or Teaching Assistant then things get weird.
