Create an exception Class called NegativeAge and an exception class named AgeTooHigh. Each of these two exception classes should have an integer member variable to hold the age. Each of these exception classes should also have a constructor to receive and set the age, and a getter function to get the age. See page 983-984 in the 8th edition text for an example. A screen shot of these pages are attached on the next page in these instructions under "extracting data from the Exception Class". Then use your class in a try-catch block. The try block should call a function named “int getAge()" that gets a user's age using a prompt and cin. The function getAge() throws the NegativeAge exception if the age provided by the user is below zero, and the AgeTooHigh exception if the age is above 120. getAge() will use the correct exception class to throw the exception and it will pass the age back to the catch block, using the exception and the exception class's age member variable.

Extracting Data from the Exception Class Sometimes we might want an exception object to pass data back to the exception handler. For example, suppose we would like the Rectangle class not only to signal when a nega- tive value has been given, but also to pass the value back. This can be accomplished by giving the exception class members in which data can be stored. In our next modification of the Rectangle class, the Negativewidth and NegativeLength classes have been expanded, each with a member variable and a constructor. Here is the code for the Negativewidth class: class Negativewidth private: double value; · 16 Exceptions, Templates, and the Standard Template Library (STL) public: Negativewidth(double val) ( value = val; } double getvalue() const { return value; } }; When we throw this exception, we want to pass the invalid value as an argument to the class's constructor. This is done in the setwidth member function with the following statement: throw Negativewidth(w); This throw statement creates an instance of the Negativewidthclass and passes a copy of the w variable to the constructor. The constructor then stores this number in Negativewidth's member variable, value. The class instance carries this member variable to the catch block that intercepts the exception. In the catch block, the value is extracted with code such as catch (Rectangle::Negativewidth e) cout « "Error: " « e.getValue() « " is an invalid value for the" « " rectangle's width.\n"; Notice that the catch block defines a parameter object named e. This is necessary because we want to call the class's getvalue function to retrieve the value that caused the exception.
