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.
- 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.
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.

Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.arrow_forward
- In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by “O”) at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection (“Left”, “Right”, “Up”, or “Down”). Based on these directions, you will try tomove the player.• If the location is valid (represented by “_”), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by “X”), you will tell the…arrow_forwardIN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type.
