    Abstract class is a class that cannot be instantiated and Interface is a blueprint of a class. Static classes are used for utility functions.

    • Abstract class is used to provide a common base for its subclasses.

    • Static classes are used for utility functions that do not require an instance of the class.

    • Static classes cannot be instantiated and all memb

  • Q4. Difference between out and ref
  • Ans. 

    Out is used to return multiple values from a method while ref is used to pass a reference of a variable to a method.

    • Out parameters must be initialized inside the method before returning.

    • Ref parameters can be initialized before passing to the method.

    • Out parameters are used when a method needs to return multiple values.

    • Ref parameters are used when a method needs to modify the value of a variable passed to it.

  • Answered by AI
  • Q5. What is Polymorphism?
  • Ans. 

    Polymorphism is the ability of an object to take on many forms.

    • It allows objects of different classes to be treated as if they were objects of the same class.

    • It is achieved through method overriding and method overloading.

    • Example: A parent class Animal can have child classes like Dog, Cat, and Bird, each with their own unique implementation of the method 'makeSound'.

    • Polymorphism makes code more flexible and reusable.

  • Answered by AI
  • Q6. Difference between Overloading and overriding
  • Ans. 

    Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as in the superclass.

    • Overloading is compile-time polymorphism while overriding is runtime polymorphism.

    • Overloading is used to provide different ways of calling the same method while overriding is used to provide a specific implementation of a method in a subcl...

    • View state can be disabled to improve performance

    • View state can also be encrypted for security purposes

  • Answered by AI
  • Q8. What are Temporary table and table variable in SQL?
  • Ans. 

    Temporary table and table variable are used to store data temporarily in SQL.

    • Temporary tables are created in tempdb and are automatically dropped when the session ends.

    • Table variables are created in memory and have a limited scope.

    • Temporary tables can be used to store large amounts of data and perform complex operations.

    • Table variables are useful for storing small amounts of data and can improve performance.

    • Both can be...

  • Answered by AI
  • Q9. What is Operator overloading?
  • Ans. 

    Operator overloading is the ability to redefine operators for custom classes.

    • Allows operators to be used with user-defined types

    • Enables the use of familiar operators with custom classes

    • Can improve code readability and reduce complexity

    • Example: '+' operator can be overloaded to concatenate strings

  • Answered by AI
  • Q10. How much time you will take to develop a login page that can authenticate user?
