Chapter 4, Problem 6PP
Write a grading
a. There are three quizzes, each graded on the basis of 10 points.
b. There is one midterm exam, graded on the basis of 100 points.
c. There is one final exam, graded on the basis of 100 points.
The final exam counts for 40% of the grade. The midterm counts for 35% of the grade. The three quizzes together count for a total of 25% of the grade. (Do not forget to convert the quiz scores to percentages before they are averaged in.) Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of 70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and any grade below 60 is an F. The program should read in the student's scores and output the student's record, which consists of three quiz scores and two exam scores, as well as the student's overall numeric score for the entire course and final letter grade.
Define and use a class for the student record. The class should have instance variables for the quizzes, midterm, final, overall numeric score for the course, and final letter grade. The overall numeric score is a number in the range 0 to 100, which represents the weighted average of the student's work. The class should have methods to compute the overall numeric grade and the final letter grade. These last methods should be void methods that set the appropriate instance variables. Your class should have a reasonable set of accessor and mutator methods, an equals method, and a tostring method, whether or not your program uses them. You may add other methods if you wish.

- IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…arrow_forwardWrite a Java program for a class named Baby. A Baby has a name of type String and an ageof type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supplymethods for setting the name, setting the age, getting the name and getting theage.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values fromthe instance variables must be done with get methods. The set method for thename instance variable should ensure that the input is not empty or containwhitespaces (otherwise set a default value). The set method for the ageinstance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an equals method for the Baby class.

Also print the surface area of the top of the tank, the surface area of the outside of the tank, and the total of these two areas in case you need to paint the tank (in square feet). So, the only inputs the class would need is the height and radius of the tank in feet. (python)arrow_forward

Include a constructor that would accept two parameters andinitialize the movie's title to the value of its first parameter and the movie'sMPAA rating to the value of its second parameter, and public rating to 0. Alsoinclude accessor member functions for title and MPAA rating. Include a memberfunction to increment the public rating that will only accept integer valuesbetween 1 and 5.

If the high is greater than or equal to 90 degrees, display the message, “Heat warning.” If the low is less than 32 degrees, display the message “Freeze warning.” If the difference between the high and low temperatures is more than 40 degrees, display the message, “Large temperature swing.”arrow_forwardIn python how do you: Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None:…arrow_forward
