A class member function that automatically initializes the data members of a class is called :_______

Answer 1

A class member function that automatically initializes the data members of a class is called a constructor.

What do you mean by constructor?

• In object-oriented programming, a constructor is a particular method of a class or structure that initializes a newly formed object of that kind. The constructor is always invoked when an object is created.
• Main obj = new Main(); In this case, the Main() constructor is invoked when the object is created. Additionally, the name variable's value is initialized. As a result, the program prints Programiz as the value of the name variables.
• The name of the constructor frequently matches that of the declaring class. They must initialize the object's data members and establish the class invariant, failing if the invariant is incorrect. A well-written constructor's outcome is an object in a usable state.
• When an object of a class is created in C++, the member functions called constructors are called. In C++, constructors fall into one of three categories: default, parameterized, or copy.
