Agenda:
Q01. What is Default Constructor in C#?
Q02. Can a Constructor return value in C#?
Q03. If every class has an implicit Default Constructor then why explicit Default Constructor required?
Q04. If a class has defined an explicit constructor, in that case, the implicit or system defined constructor will be invoked or not?
Q05. Can a class be inherited which has no Default Constructor in C#?
Q06. In which order the constructors are executed in case of inheritance?
Q07. Can a struct have Default Constructor in C#?

A constructor is a special method that is used to initialize the data members or fields of the class or structure while creating the object of the class or structure.

A constructor is nothing but a method without any return type which has the same name as the class or struct name. Constructors are called automatically when we create the object of the class.

Default constructors are parameterless constructors. They are two types:

1.Implicit Default Constructor or System-Defined Default Constructor:
It is a special system-defined instance constructor without any parameter. When we do not create any constructor in the class, the compiler will automatically create a default constructor of the class.

2. Explicit Default Constructor or User-Defined Default Constructor:
It is a user-defined instance constructor without any parameter.
A structure cannot have an explicit default instance constructor but it can have a static constructor that is always parameterless.
