Question 2 You are about to create a simple 2D shooting game. i) Create appropriate structures with the following information: Bullet isAvailable: bool Gun type: The gun type (e.g. Rifles or Pistol) bulletSize: Total bullets in the gun (e.g. 6 bullets in Pistol) bullets: An array of Bullet type. Maximum 100 bullets applied in the game. ii) Assume you have defined a variable called myWeapon as follows: Gun myWeapon; myWeapon.model "Machine Gun"; myWeapon.size 80; Write a code fragment to reload all the gun bullets status to true. iii) Create a function called shot that takes in a reference parameter as Gun type. The function displays the message "Reload" if the first bullet is empty. Otherwise, for every single bullet, it displays "Bang" and set the last bullet to false.
10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
8. 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 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade. Input Validation: Do not accept test scores less than zero or greater than 100.

Lotto Program C++Write a program that simulates the Powerball lottery. 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.

Class and Data members: Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and course for which the grades are earned. Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is x̄ = ∑xi / n where xi is the value of each grade and n is the total number of grades in the vector. A member function to determine the lowest…
