IComparable and ISerializable are abstract interface classes, Person is derived from them both (multiple interface inheritance).

Implement the missing functions in Person.h and Person.cpp. You may need to declare new functions as well.

Decomposition of the program:

• IComparable.h, ISerializable.h, Person.h: class declaration headers;
• Person.cpp: implementation of class members declared in the header;
• Main.cpp: the main program with testing code.

Sorter.h declares a Sorter class that is a collection of multiple sorting algorithms. Each sorting algorithm takes an array of IComparable* pointers. These functions can sort any type that implements the IComparable interface such as our Person type.

Add a Sorter.cpp file and implement bubble sort and quicksort there. Test your solution in Main.cpp.

There are many other sorting alorigthms. Add another one and test it in the main function. Examples: merge sort (in place or not), insertion sort.

Add another sortable type. Implementing the IComparable interface makes a type sortable. Create an array of your type and sort it via the Sorter class. Test your solution in the main function.

Examples of sortable types:

1. Complex numbers. Should be sorted by absolute value (length of the vector).
2. Rational numbers as a ratio of two integers p/q. Numerical sorting is well defined.
3. 3D vectors. Should be sorted by length.

Completing one or both optional tasks can make up for mistakes in the first task.
