You need to create a method that can be called by using a varying number of parameters.
What should you use?
A. derived classes

Answer: D
Explanation:
Member overloading means creating two or more members on the same type that differ only in the number or type of parameters but have the same name.
Overloading is one of the most important techniques for improving usability, productivity, and readability of reusable libraries.
Overloading on the number of parameters makes it possible to provide simpler versions of constructors and methods.
Overloading on the parameter type makes it possible to use the same member name for members performing identical operations on a selected set of different types.
