In the context of class SuperVar, what C++ feature ensures that each type of data (char, int, float) has its own constructor implementation?

  1. Polymorphism

  2. Function overloading

  3. Class instantiation

  4. Union encapsulation

The correct answer is: Function overloading

Generally speaking, polymorphism refers to the ability of an object to take on various forms. While this may be an important feature in some regards, function overloading is specifically used for having multiple functions with the same name but different parameters. In this context, polymorphism is not the correct answer. Class instantiation simply refers to the process of creating an instance of a class, but it does not dictate or ensure that each type of data has its own constructor implementation. Lastly, union encapsulation is a concept in C++ that allows different data types to share the same memory space, which is not relevant to the question at hand. Therefore, function overloading is the correct answer as it specifically ensures that each type of data has its own constructor implementation.
