C# Level 2

This level 2 quiz will give you in-depth and thorough understanding of OO concepts. Do you know . . .

• how to look at a program and see its overall structure?

• why Main must be static?

• why a variable declared inside or outside a method is conceptually different?

• whether it is correct to say polygon is a class and circle is an object?

• whether a variable has a default value or not depends on its nature?

• what are the implications of adding the modifier static to a variable?

• whether a class will deal with byte or character data stream from its name?

. . . you will learn this and more from the quiz!

Oh yeah, is it also correct to say stationery is a class and pen is an object? How do you tell what is a class and what is an object?

There are 100 questions covering object-oriented concepts, classes and objects, class structure, superclasses, reference types, method calls with reference types, customized value types (structs and enums), exceptions, IO streams, serialization, and so on

Coming soon! Level 3 will deal with polymorphism, software reuse techniques, interfaces and other advance stuff. And yes, you may know what an abstract class is. Or an abstract method. But most important of all, do you know *why* we have such oddities?
