The access modifier of the default constructor is usually public.

• The default constructor is a special constructor that is automatically generated by the compiler if no constructor is defined in the class.

• The access modifier determines the visibility of the constructor.

• By default, the access modifier of the default constructor is public, allowing it to be accessed from anywhere.

• However, it can also be explicitly defined...read more

let and var are both used to declare variables in JavaScript, but they have different scoping rules.

• let has block scope, while var has function scope

• let can be updated but not re-declared in the same scope, while var can be both updated and re-declared

• let is a relatively new addition to JavaScript, while var has been around since the beginning

Polymorphism allows objects of different classes to be treated as if they were the same type. Virtual keyword is used in overloading to enable dynamic binding.

• Polymorphism enables code reuse and flexibility in object-oriented programming.

• Virtual keyword is used in function overloading to allow the compiler to determine which function to call at runtime based on the type of object.

• Without virtual keyword, the function c...read more

Internal access modifier limits the access to within the same assembly.

• Internal members can be accessed only within the same assembly.

• It is useful for hiding implementation details from other assemblies.

• It is also useful for creating helper classes that are only used within the same assembly.

An abstract class is a class that cannot be instantiated and is used as a base class for other classes.

• An abstract class can have abstract and non-abstract methods.

• Abstract methods have no implementation and must be implemented by the derived class.

• An abstract class can have constructors, fields, and non-abstract methods.

• An abstract class is declared using the 'abstract' keyword.

• Example: abstract class Shape { abstract
