10 Questions
What is the problem with the solution of creating a class (ex. ListOfNumbers) to copy the contents of the array to a new array?
It leads to code duplication when creating a list of a different data type
What are the drawbacks of using the data type 'object' to solve the problem?
One list can accept different types of data and casting must be used repeatedly
What is one big limitation of arrays mentioned in the text?
Inability to easily change their size by adding and removing items
What is the motivation for using generics as mentioned in the text?
To avoid code duplication when creating lists of different data types
What is the problem with using the data type 'object' in the context mentioned in the text?
It requires casting to be used repeatedly and allows one list to accept different types of data
What is the meaning of 'static' in C#?
Static in C# means something which cannot be instantiated. You cannot create an object of a static class and cannot access static members using an object.
What are the applicable elements for the 'static' modifier in C#?

What are the restrictions for a static class in C#?
A static class in C# can only contain static data members, static methods, and a static constructor. It is not allowed to create objects of the static class.
What does it mean when a member of a class is declared as static in C#?
When a member of a class is declared as static in C#, it means that no matter how many objects of the class are created, there is only one copy of the static member.
What are the characteristics of a static class in C#?
A static class in C# can only contain static data members, static methods, and a static constructor. It cannot be instantiated and does not allow the creation of objects.
