Q2) (Perfect Numbers) An integer number is said to be a perfect number if its factors,
including 1 (but not the number itself), sum to the number. For example, 6 is a perfect
number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number
is a perfect number. Use this function in a program that determines and prints all the perfect
numbers between 1 and 1000. Print the factors of each perfect number to confirm that the
number is indeed perfect. Challenge the power of your computer by testing numbers much
larger than 1000.
(Enhancing Class Rectangle) Create a more sophisticated Rectangle class than the one youcreated in Exercise 17.11. This class stores only the Cartesian coordinates of the four corners of therectangle. The constructor calls a set function that accepts four sets of coordinates and verifies thateach of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set function also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member functions that calculate the length, width, perimeter and area. The length is the larger of the twodimensions. Include a predicate function square that determines whether the rectangle is a square

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?
