C++ Define a problem with input, output, and Exception Handling. If no output explain the reason why and what you are going to do make sure it does not happen again aka learning from your mistakes. Problem: Design: Code: Output:

C++ 1: 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"). The class named “Variable” should generate a "VarNameException" whenever the caller tries to create the Variable object with a bad name. 2: 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…

Arithmetic Exception   Arman has a shop where he provides stuff on rent. The whole payment system is computerised. A customer has to enter the item name, item type, cost, and the number of days they have taken the item for rent. The system then tells them the cost per day. But there is a problem with the machine that if the number of days entered is not an integer value then the system would crash. To handle this, Arman decided to upgrade the software and use exception handling in case the customer entered any invalid input it should display " Number of days x is invalid".Write a C++ program to find the item cost per day with the cost for n days given. The arithmetic exception has to be thrown if the n is less than or equal to zero.Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.The class Item has the following private data members.…
