Chapter 7, Problem 12PC
Grade Book
A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores:
| Test Score | Letter Grade |
| 90-100 | A |
| 80-89 | B |
| 70-79 | C |
| 60-69 | D |
| 0-59 | F |
Write a
The program should allow the user to enter each student’s name and his or her four test scores. It should then calculate and display each student’s average test score, and a letter grade based on the average.
Input Validation: Do not accept test scores less than 0 or greater than 100.

(Airplane Seating Assignment) | Write a program that can be used to assign seats for a commercial airplane. The airplane has 13 rows, with six seats in each row. Rows 1 and 2 are first class, rows 3 through 7 are business class, and rows 8 through 13 are economy class.
Use two parallel arrays:
a one-dimensional array to store the row number of the seats (Row #)
a two-dimensional array of 13 rows and 6 columns to store the seat assignments (*) and seat letters (A-F)
Your program must prompt the user to enter the following information:
Reserve a seat (Yes (Y/y) or No (N/n))
Assign ticket type (first class (F/f), business class (B/b), or economy class (E/e))
Select desired seat (1-13 and A-F)

In Powerball, a ticket is comprised of 5 numbers between 1 and 69 that must be unique, and a Powerball number between 1 and 26. The Powerball does not have to be unique. Hint: You can use an array to represent the 5 unique numbers between 1 and 69, and an integer variable to represent the powerball. The program asks the player if they'd like to select numbers or do a 'quickpick', where the numbers are randomly generated for them. If they opt to select numbers, prompt them to type the numbers in and validate that they are unique (except the powerball), and in the correct range. The program then generates a 'drawing' of 5 unique numbers and a Powerball, and checks it against the user's lotto ticket. It assigns winnings accordingly. Because it is so rare to win the lottery, I suggest hard coding or printing values to when testing the part of the program that assigns winnings.arrow_forwardC++ arrays task The scientist monitors the movement of a particle suspended on the surface of the water and records its coordinates every n seconds. make a program that calculates the minimum, average, and maximum velocities of the particle and the distance traveled by the particle.
