A Subclass is a class that inherits from one or more base classes. d) Fields What is difference between Abstract class and Interface (Abstract vs Interface)? WPF Dispatcher - Introduction and How to use? Today, it is possible to write C# code not only on Windows systems but also on Mac and *NIX (Linux & UNIX) distributions, thanks to open source initiatives such as .NET Core, ASP.NET Core, and Xamarin. Question 8. e) base, Q-10. It is the blueprint/plan/template that describes the details of an object. Minimum one abstract method is compulsory.. Overloading is static Binding, whereas Overriding is dynamic Binding.

You can unsubscribe anytime. In OOPS we develop our code in modules. Any method that accepts an instance of Supertype will also be able to accept an instance of Subtype without any casting required by the client side. 9. c) Number of arguments may vary If the function is defined outside the class cannot access such information. 7. This process of modeling is called abstraction. Commonly Asked Operating Systems Interview Questions | Set 1 Following are the operators that cannot be overloaded -. d) -25 -100000 -12.34, Q-15. Required fields are marked *. A parameter is a variable used during the declaration of the function or subroutine, and arguments are passed to the function body, and it should match with the parameter defined.

Why C# doesn’t support multiple inheritance? 1. true Compile Time Polymorphism: Compile time polymorphism means compiler knows which function should be called when a polymorphic call is made. Which of the following members of the class allow declaring them as virtual?

ViewModelBase is an abstract class, then we knows this class will only inherits by ViewModels.

Clients of the object only see these behaviors and by only these behaviors clients can modify the data. Keywords, identifiers, constants, string literals, and operators are examples of tokens. a) overloads

No, we do not require a parameter for constructors. Q-5. The above question can be asked in another way. That hidden data can be restricted to the members of that class. Which of the following keywords can be used to overload user-defined types by defining static member functions? Abstraction is a technique of taking something specific and making it less specific. 5. There are five types of access modifiers, and they are as follows: Sealed modifiers are the access modifiers where the methods can not inherit it. a) Method overloading These modules are assembled together as software.

BaseClass. d) None of the mentioned, Q-2. OOP paradigm is mainly useful for relatively big software.
