What is a constructor? What is its function? What happens if a developer writes no code for a class constructor?
What will be an ideal response?
When a class is instantiated into an object using the New keyword, a special procedure in the instantiated class called a constructor is executed. The constructor prepares the object for use in the program. The code in the constructor executes before any other code in the object. In addition to processes automatically completed by the constructor, the user can choose to write code for the constructor as well. If the developer writes no code for a class constructor, Visual Basic automatically generates whatever processing must be accomplished to prepare the object for use. The developer can include a constructor with no executing code.
