Design different class TestRectangle class in separate source file, which will contain main function. From this main function, create 5 Rectangle objects by taking all necessary information from the user.   The class has attributes length and width, each of which defaults to 1. It should have member functions that calculate the perimeter and area of the rectangle. It should have set and get functions for both length and width. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0.

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate.   Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)   ClassRegistration -…

Using object-oriented principles, write a C++ program that will analyze a year's worth of rainfall data. Within the class, create a private member function called getData that will read in the data from an input file called rain2019.txt. This file contains the total rainfall for each of the 12 months. Read the contents of this file into a float array. The class should have four private member functions that compute and return totalRainfall, averageRainfall, driestMonth, and wettestMonth. The last two private member functions return the number of the month with the lowest and highest rainfall amounts, not the amount of rain that fell in those months. Notice that the month number can be used to obtain the amount of rain that fell those months. Create a private member function called displayReport that will print a summary rainfall report similar to the following (NOTE: this is only an example of format, not accurate data):  2019 Rain Report for Alachua County Total rainfall: 34.19…
