A copy constructor. Overloaded == operator: This will return true if arrays in two different Numbers objects have the same sum of arrays, false otherwise. Overloaded < operator: Returns true if the sum of the numbers in the array of one Numbers object is less than the sum of the numbers in the array of the second Numbers object. For example, a < b is true if the numbers in a's array have a smaller sum than the numbers in b's array. Returns false otherwise. Overloaded postfix ++ operator: Increments every element in the object's array by 1. Overloaded [ ] operator: allows updating the appropriate element of the Numbers object's array. The method does nothing should terminate the program (calling exit) (note: updated on 11/6) if the user specifies an invalid index. Overloaded << operator: allows a Numbers object to be used with cout. For example: cout << a; This will cause the contents of the object's array to be displayed on the screen similar to this: [8, 6, 7, 5, 3]. Overloaded assignment operator: copies the contents of one Numbers object to another

Question
For the numbers class add the following methods:
- A copy constructor.
- Overloaded == operator: This will return true if arrays in two different Numbers objects have the same sum of arrays, false otherwise.
- Overloaded < operator: Returns true if the sum of the numbers in the array of one Numbers object is less than the sum of the numbers in the array of the second Numbers object. For example, a < b is true if the numbers in a's array have a smaller sum than the numbers in b's array. Returns false otherwise.

Demonstrate the class in a program.
The class does not interact with the user in any way. All interactions with the user are done in the main function. Make sure all accessors are correctly marked const.
