Which of these is not an object oriented programming facility?
why C programming language is not an object-oriented programming facility- However, the C programming language is not an object-oriented programming language, so it will not allow you to create or inherit classes and objects. There is no built-in feature to create new class data.
What are the pros and cons of Object Oriented Programming?

- It can cause duplication.
Why do people not like Object-Oriented Programming?
Originally Answered: Why are so many developers hating on object-oriented programming? It’s because over time software trends and best practices have evolved and the “best” way of doing things isn’t as compatible with OOP. Objects aren’t becoming less popular, classes are. The main reason is the emphasis on state.
Are limitations and disadvantages the same?
As nouns the difference between limitation and disadvantage
is that limitation is the act of limiting or the state of being limited while disadvantage is a weakness or undesirable characteristic; a con.
Why is object oriented programming used?
Object-oriented programming (OOP) is a programming paradigm that allows you to package together data states and functionality to modify those data states, while keeping the details hidden away (like with the lightbulb). As a result, code with OOP design is flexible, modular, and abstract.
What are the drawbacks of procedural languages explain the need of object oriented programming with suitable program?
Disadvantages of Procedural Programming
A major disadvantage of using Procedural Programming as a method of programming is the inability to reuse code throughout the program. Having to rewrite the same type of code many times throughout a program can add to the development cost and time of a project.
Why we use object oriented programming in software engineering give at least 3 reasons?
Here’s a look at some of OOP’s top benefits:
- Modularity for easier troubleshooting. When working with object-oriented programming languages, you know exactly where to look when something goes wrong. …
- Reuse of code through inheritance. …
- Flexibility through polymorphism. …
- Effective problem solving.
Which is not an object oriented programming language?

Which feature may be violated if we don’t use classes in a program?
Which feature may be violated if we don’t use classes in a program? Explanation: All the features are violated because Inheritance and Encapsulation won’t be implemented.
What is the opposite of object oriented programming?
Functional programming
Functional programming, as a result, has been gaining traction in awareness and general application. This is because functional programming is the polar opposite of what object-oriented tries to be. It discards the concepts of states completely and prevents unwanted relationships from forming.
Which among the following is not a use of object?
Which among the following is not a use of object? Explanation: The objects can’t be used to define any member function. Member functions must be defined by the class only.
Which is not feature of OOP in general definition?
Right answer is (c) Duplicate/Redundant data. To explain: Duplicate/Redundant data is dependent on programmer and hence can’t be guaranteed by OOP. Code reusability is done using inheritance. Modularity is supported by using different code files and classes.

Which among the following Cannot be used for the concept of polymorphism?
Which among the following can’t be used for polymorphism? Explanation: Static member functions are not property of any object. Hence it can’t be considered for overloading/overriding. For polymorphism, function must be property of object, not only of class.
Which among the following Cannot be a member of a class?
Friend function is not a member of the class.
Which of these keywords is not a part of exception handling?
Explanation:None. 6. Which of these keywords is not a part of exception handling? Explanation: Exception handling is managed via 5 keywords – try, catch, throws, throw and finally.
Which of the following is NOT type of class?
1. Which of the following is not type of class? Explanation: Only 9 types of classes are provided in general, namely, abstract, final, mutable, wrapper, anonymous, input-output, string, system, network. We may further divide the classes into parent class and subclass if inheritance is used.
Which class Cannot create its instance?
No, you cannot create an instance of an abstract class because it does not have a complete implementation. The purpose of an abstract class is to function as a base for subclasses. It acts like a template, or an empty or partially empty structure, you should extend it and build on it before you can use it.
Which of the following Cannot be used with keyword virtual?
2. Which of the following cannot be used with the virtual keyword? Explanation: Virtual keyword cannot be used with constructors as constructors are defined to initialized an object of particular class hence no other class needs constructor of other class.
Which of the following letter is not used to represent a class?
Which of the following letter is not used to represent a class? Explanation: There is no amplifier called Class K. There are only A, B, C, D, E/F, G, H, S.
Which class Cannot be inherited?
An abstract class cannot be inherited by structures. It can contains constructors or destructors. It can implement functions with non-Abstract methods.
When and why one can not create an object of a class?
you can’t create a object of abstract class because there is an abstract method which has nothing so you can call that abstract method too. If we will create an object of the abstract class and calls the method having no body(as the method is pure virtual) it will give an error.
Why object can not be created for an abstract class though it contains a constructor?
No, we can’t create an object of it. As know abstract class is not the complete class. because an abstract class has abstract method(Methods without body). Although an abstract class has a constructor if you will try to create an object of it, It will throw compile time exception.
