3. RetailItem Exceptions Programming Challenge 4 of Chapter 6 required you to write a RetailItem class that holds data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand.
Demonstrate the exception classes in a program.
/**
*Description: This program will displays a string without any user interaction
*Class: Fall - COSC 1437.81002
*Assignment1: Hello World
*Date: 08/15/2011

*@version 0.0.0
*/
For each method, you will also be required to create docstring as follows:
/**
* @param String as args
* @return Termination code as int, 0 for normal, anything else is error condition
* @throws Nothing is implemented
*/

Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using this zero- argument constructor, getMessage should return "Core Breach! Evacuate Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor.

You are expected to use the standard exception classes to try functions, throw objects, and catch those objects when problems occur.

Instances of the class will be thrown based on the following conditions: The value for a month number is not between 1 and 12 The value for a month name is not January, February, March, … December Develop a class named Month. The class should define an integer field named monthNumber that holds the number of a month. For example, January would be 1, February would be 2, and so forth. In addition, provide the following methods: A no-argument constructor that sets the monthNumberto 1. An overloaded constructor that accepts the number of the month as an argument. The constructor should set the monthNumberfield to the parameter value if the parameter contains the value 1 – 12. Otherwise, throw an InvalidMonthException exception back to the caller.

- part1: Define a class named “Variable” that manages a variable name (string) and a description (string). It should not provide the default constructor. And the “VariableString” class that must inherit from the "Variable" class. This class manages a variable name (string), description (string), and value (string). Define a new exception class “VarNameException” that must inherit from the C++ runtime_error class. This class will capture the error case (generate an exception and capture reason and error value) for a variable name when it does not start with a letter (lower case or upper case) or contains at least one blank (for instance: "9name", "*name" or "first name"). part2: Write a function “createVariableObject” that will read the variable name, description, and a value (string) from the user and create a dynamic Variable or VariableString depending on the value: if the user provides an empty string value, it will create a Variable object, otherwise it will create a VariableString…arrow_forwardin C++ Define a new exception class named “VarNameException” that must inheritfrom the C++ runtime_error class.
