Which among the following represents correct constructor?

Correct Answer (Detailed Explanation is Below)

A. classname()

Detailed Explanation

Explanation:

In C++, a constructor:

• Has the same name as the class

• Does not have a return type (not even void)

• Is used to initialize objects

  
  

So, the correct format of a constructor is:

✔ classname()

Other options are incorrect because:

• Constructors do not start with -

• They cannot have brackets without proper syntax

• They must exactly match the class name
