A company wants their payroll system developed in OOP in C++ and they have approached you for the basic structure and functionality. They want an object with name and salary properties. The object should have a default constructor that initialises the properties to null and a parameterised constructor. The object should also have two accessors (methods of accessing the contents of a property), one for each property. They also want a method that will compare two objects and tell which has a better salary than the other.
