To do this, you should create a TestGrader class. The class will have an answers array of 20 characters, which holds the correct test answers. It will have two public member functions that enable user programs to interact with the class: setKey and grade. The setKey function receives a 20-character string holding the correct answers and copies this information into its answers array. The grade function receives a 20-characte r array holding the test taker’s answers and compares each of their answers to the correct one. An applicant must correctly answer 15 or more of the 20 questions to pass the exam. After “grading” the exam, the grade function should create and return to the user a string that includes the following information:
• A message indicating whether the applicant passed or failed the exam
• The number of right answers and the number of wrong answers
• A list of the question numbers for all incorrectly answered questions
The client program that creates and uses a TestGrader object should first make a single call to setKey, passing it a string containing the 20 correct answers. Once this is done, it should allow a test taker's 20 answers to be entered, making sure only answers of A-D are accepted, and store them in a 20-character array. Then it should call the grade function to grade the exam and should display the string the function returns. The program should loop to allow additional tests to be entered and graded until the user indicates a desire to quit.

- Golf scores record the number of strokes used to get the ball in the hole. The expected number of strokes varies from hole to hole and is called par (i.e. 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par: "Eagle": number of strokes is two less than par "Birdie": number of strokes is one less than par "Par": number of strokes equals par "Bogey": number of strokes is one more than par Given two integers that represent par and the number of strokes used, write a program that prints the appropriate score name. Print "Error" if par is not 3, 4, or 5 need answer in pythonarrow_forwardGolf scores record the number of strokes used to get the ball in the hole.

- C#arrow_forwardGreenLawn a local lawn care company has different pricing policies for its customers. GreenLawn sends out monthly invoices and will give discounts if payments are made within 5 days. The discounting policy is as follow: If the amount of the monthly bill is greater than $300, subtract 4 percent from the invoice; if the amount is between $300 and $100, subtract a 2-percent discount; if the amount is less than $100, do not apply any discount. All bills made via the web automatically receive an extra 3-percent discount. Develop a decision for GreenLawn discounting decisions.

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_forward
