- Description—The Description property should hold a brief description of the item.
- UnitsOnHand—The UnitsOnHand property should hold the number of units currently in inventory.
- Price—The Price property should hold the item’s retail price.
Write a constructor that accepts arguments for each property.
The application should create an array of three RetailItem objects containing the following data:

console application named SalesTransactionDemo that declares several SalesTransaction objects and dispplays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and comission rate. Include three constructors for the class. Once constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value time commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all other fields to 0. An overloaded + operator add the sales values for two SalesTransaction objects.

- C++ Stars This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its destructor called,…arrow_forward(Rectangle Class) Create class Rectangle.

A constructor that accepts the number of the month as an argument. It should set the monthNumber value to the value passed as the argument. If a value less than 1 or greater than 12 is passed, the constructor should throw an InvalidMonthNumberException. A constructor that accepts the name of the month, such as “January” or “February”, as an argument. It should set the monthNumber field to the correct corresponding value.
