A student must correctly answer 15 of the 20 questions to pass the exam.
Write a class named DriverExam that holds the correct answers to the exam in an array field. The class should also have an array field that holds the student’s answers. The class should have the following methods:
- passed. Returns true if the student passed the exam, or false if the student failed
- totalCorrect. Returns the total number of correctly answered questions
- totalIncorrect. Returns the total number of incorrectly answered questions
- questionsMissed. An int array containing the question numbers of the questions that the student missed
Demonstrate the class in a complete program that asks the user to enter a student’s answers, and then displays the results returned from the DriverExam class’s methods.
Input Validation: Only accept the letters A, B, C, or D as answers.

- An online book club awards points to its customers based on the number of bookspurchased each month . Points are awarded as follows:Books Purchased01234 or morePoints Earned051530soWrite a program that asks the user to enter the number of books purchased this monthand then displays the number of points awarded .arrow_forwardPopulation Tracker Learning Objective: Using Python Repetition and Loop Statements Problem Description Write a Python program (Console and GUI) that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user to enter the following information: starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. For example, assume the user enters the following values: Starting number of organisms: 2 Average daily increase: 30% Number of days to multiply: 10 The program should display the following table of dataarrow_forwardTime CalculatorWrite a program that asks the user to enter a number of seconds.-There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes and leftover seconds in that many seconds.-There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours, minutes, and leftover seconds in that many seconds.-There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days, hours, minutes, and leftover seconds in that many seconds.arrow_forward
- Percentage of vehicles: Write an interactive program that asks the users to input the number of cars, trucks and suv that entered a parking lot. Your progam should then calculate the percetages of each vehicle type and display the result.arrow_forwardSoftware Sales A software company sells a package that retails for $99. Quantity discounts are given below: Quantity Discount 10–19 20% 20–49 30% 50–99 40% 100 or more 50% Design a program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.arrow_forwardComputer Science PYTHON PROGRAMMING Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user's guess is higher than the randomly generated number, the program should display "Too high, try again." If the user's guess is lower, the program prints "Too low, try again." If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over. Keep track of the number of guesses a user makes before guessing the correct one and display it with the congratulatory message when the user guesses the number correctly. For this assignment, create functions that: generate and return a random number between 1 and 100. format and return the failure and congratulatory messages. Put these function in a module called helper.py and put the rest of the code in game.py. The game module must import the helper module. Please provide both helper.py & game.py…arrow_forward
- Widgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forwardlanguage JAVAarrow_forwardPYTHON programming solotion Develop a program that allows the user to enter a start value of 1 to 4, a stop value of 5 to 12 and a multiplier of 2 to 8. The program must display a multiplication table with results using these values. For example, if the user enters a start value of 3, a stop value of 7 and a multiplier value of 3, the table should be displayed as follows: Multiplication Table 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 additionally Each multiplication problem must be displayed with a problem number. The program must prompt the user to enter an answer to each of the multiplication problems. The correct answer should be displayed after the user enters an answer. A message should be displayed informing the user that the answer entered was correct or incorrect followed by an appropriate motivating comment. A running record of the number of correct and incorrect responses must be kept. After all the problems have been presented the user must be informed of…arrow_forward
- C# Programarrow_forwardUse C Language Airline Reservation System A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You are to write a program to assign seats on each flight of the airline's only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1-5). If the person types 2, then your program should assign a seat in the economy section (seats 6-10). Your program should then print a boarding pass indicating the person's seat number and whether it is in the first class or economy section of the plane. Use a single-subscripted array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of…arrow_forwardRandom Number Guessing Game Create an application that generates a random number in the range of 1 through 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over. Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.arrow_forward
