Question
Chapter 8, Problem 36RQE
A)
Program Plan Intro
Array:
An array is a data structure which stores multiple values of same types of data; the array values are stored in continuous memory locations.
- Size of an array has been declared inside a square bracket, which is named as size declarator.
- The size declarator must be declared as an integer with a value greater than “0” and the number inside the brackets represents the number of elements that the array can hold.
Structure array:
The structure needs an array if the items needs to be grouped together.
- Array is a “derived” data type and it contains similar elements.
- The array index starts with 0.
- If the size of the array is 4, then the index values are “0”, “1”, “2”, and “3”.
Syntax:
struct_name array_name[size];
Example:
Book name[20];
Explanation:
“Book” is a structure name, “name” is an array name, and the value “20” is the “size” of an array.
B)
Program Plan Intro
Array of Objects:
Object is an instance of the class. Objects of the class can also be given in the form of an array, in which the array values are passed into an overloaded constructor.
Syntax: classname object[size];

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.
Fill-in-the-Blank
To allow an array of structures or an array of objects to be initialized, the struct or class declaration should include a(n) _________.
Create a structure representing a student object with the following members
regno.
courseid
unitsRegistered: This should be an array of the course units you registered to capture marks
unitsmarks: This should be an array to store the marks for the units registered. Find a way to relate the two.
firstname
surname
address
By using the structure above, write a program that populates the details of a student and compute the average, and the grade as well as the total marks. This task should be accomplished by writing functions for getData() - to populate the structure, printStudent() - to display the detail of the student, computeGrade() - to compute the grade of the student and computeMean() that computes the mean of the students: Pass the appropriate data
NB: The function getData() - is a subroutine and uses structure as a reference - input, same concept to printData()
Consider that your class has 10 students. Compute the class mean and standard deviation, highest class mark and lowest…

Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function.

You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…arrow_forwardWrite a program that uses two structures Name and Student to store the following information for multiple students: Create a nameType structure that consists of First Name, Middle Initial, and Last Name Create a studentType structure that contains student information (Include the nameType structure within the Student information structure): Name ID email GPA Program (an enum type named programType containing programs such as CSCI, DBMS, INFM, SDEV) Suppose that a class has at most 20 students.
