Textbook Question
Chapter 6, Problem 5PP
Define a class for a type called Fraction. This class is used to represent a ratio of two integers. Include mutator functions that allow the user to set the numerator and the denominator. Also include a member function that returns the value of the numerator divided by the denominator as a double. Include an additional member function that outputs the value of the fraction reduced to lowest terms. For example, instead of outputting 20/60 the function should output 1/3. This will require finding the greatest common divisor for the numerator and denominator, and then dividing both by that number. Embed your class in a test program.

Quick java class question
Program SpecificationUsing python, design a class named PersonData with the following member variables:
lastName
firstName
address
city
state
zip
phone
Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables:
customerNumber
mailingList
The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables.
Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling.

Overload the above constructor and use this keyword to set the values of width, height & depth. Provide getters/setters for data members. Write a function calculateVolume() which calculates the volume of the box.

Also define a functionnamed getLifespan that returns a string with the value “unknown lifespan.” Next, define a Dog class that is derived from Pet. The Dog class should have aprivate member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors.Redefine the getLifespan function to return “Approximately 7 years” if the dog’sweight is over 100 pounds and “Approximately 13 years” if the dog’s weight isunder 100 pounds.

Constructor: does not take any parameters and initializes the length(L) and width(W) to zero. - A function called getArea which returns the area of the rectangle. A function called getPerimeter which returns the perimeter of the rectangle. {note: The area of a rectangle =L*W, and its perimeter = 2*(L+W) } Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.arrow_forwardDefine a class named StudentGrader that has the following attributes defined within the initialization function: homeworkAvg as float midtermScore as integer finalScore as integer attendance as floata.
