Complete Modern C++ - Project - Part IX (RTTI Basics)

The video tutorial covers the implementation of a minimum balance feature in a checking account class, emphasizing the importance of setting and querying this value externally. It discusses the challenges of downcasting pointers and the dependencies it creates, highlighting design concerns. The tutorial introduces the concept of Run-Time Type Identification (RTI) in C++, explaining how to use the type ID operator to determine the type of objects at runtime, especially in polymorphic scenarios. The video concludes with practical examples of using type ID for decision-making based on object types.

What is the purpose of the member variable 'Minimum balance' in the checking class?

Explain the process of downcasting an account pointer to a checking pointer.

What are the potential risks of blindly downcasting an account pointer?

What should be checked before downcasting an account pointer to ensure safety?

What is the significance of the type ID operator in C++?

Describe how to use the name function from the type info class.

How does the type ID operator behave differently for polymorphic and non-polymorphic types?
