In this quiz, we will test your understanding of C# structures and their differences from classes. Structures, while sharing some similarities with classes, have unique characteristics such as being value types, which are copied by value and stored on the stack. You will be challenged on the concepts of value vs. reference types, immutability, copying behavior, and when to choose structures over classes. This quiz will also explore the key features of structures, such as their inability to support inheritance, their ability to implement interfaces, and other related concepts.
