9.11: Array Expander
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is twice the size of the argument array. The function should copy the contents of the argument array to the new array, and initialize the unused elements of the second array with 0. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your array expander function, and prints the values of the new expanded array on standard output, one value per line. You may assume that the file data has at least N values.

Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.

Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.

And office now has a total of 35 employees 11 were added last year the year prior there was a 500% increase in staff how many staff members were in the office before the increase

Answers

There were 5 staff members in the office before the increase.

To find the number of staff members in the office before the increase, we can work backward from the given information.

Let's start with the current total of 35 employees. It is stated that 11 employees were added last year.

Therefore, if we subtract 11 from the current total, we can determine the number of employees before the addition: 35 - 11 = 24.

Moving on to the information about the year prior, it states that there was a 500% increase in staff.

To calculate this, we need to find the original number of employees and then determine what 500% of that number is.

Let's assume the original number of employees before the increase was x.

If we had a 500% increase, it means the number of employees multiplied by 5. So, we can write the equation:

5 * x = 24

Dividing both sides of the equation by 5, we find:

x = 24 / 5 = 4.8

However, the number of employees cannot be a fraction or a decimal, so we round it to the nearest whole number.

Thus, before the increase, there were 5 employees in the office.

Simply said, a function is a “chunk” of code that you may reuse repeatedly rather than having to write it out several times. Programmers can divide an issue into smaller, more manageable parts, each of which can carry out a specific task, using functions. Thus, option D is correct.

What are the different functions used in programming?

These coding building pieces are known as functions in programming. There are input and output in every programming function. The function has instructions that are used to translate its input into output.

A function is a section of code that only executes when called. You can supply parameters—data—to a function. Functions are used to carry out certain activities and are crucial for code reuse: One code definition can be used numerous times.

Suppose there is exactly one packet switch between a sending user and a receiving user. The transmission rates between the sending user and the switch and between the switch and the receiving user are R1 and R2, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L?

Answers

Answer:

$L(\frac{1}{R_1}+\frac{1}{R_2} )$

Explanation:

$R_1$ is the transmission rates between the sending user and the switch while $R_2$ is the transmission rates between the switch and the receiving user and the length of the packet is L

Considering no propagation delay the time taken to transmit the packet from the sending user to the switch is given as:

$t_1=\frac{L}{R_1}$

the time taken to transmit the packet from the switch to the receiving user is given as:

$t_2=\frac{L}{R_2}$

therefore the total end-to-end delay to send a packet is:

$t=t_1+t_2=\frac{L}{R_1}+\frac{L}{R_2} =L(\frac{1}{R_1}+\frac{1}{R_2} )$

Answers

The given state machine is in State C and receives the string 100010, the ending state of the state machine will be State B (option B).

What is the state machine? A state machine is a mathematical model of a system. It is an abstract machine that can be in exactly one of a finite number of states at any given time. State machines are often used for stateful entities such as computers, processors, and other electronic devices.

How to solve the problem? We start from the starting state State A and follow the given string 100010.

State A: The first symbol of the string is 1, so we move from state A to state B.

State B: The second symbol of the string is 0, so we move from state B to state D.

State D: The third symbol of the string is 0, so we move from state D to state E.

State E: The fourth symbol of the string is 0, so we move from state E to state F.

State F: The fifth symbol of the string is 1, so we move from state F to state B.

State B: The sixth and last symbol of the string is 0, so we remain in state B, and it's our ending state. Therefore, the ending state of the state machine will be State B.

The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes:
author: String
tiltle: String
isbn : String
- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:
The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the authorâ€™s name (we assume that all names are at least three letters long), and c is the last character of the isbn.
- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see sample

- Your code should display the list of all books keyed in by the user
Whatâ€™s new in HW5:
- Create an abstract class that you call Book. The class Book should have the fields and the code that is shared by both the BookstoreBook and the LibraryBook classes. Both of those classes extend the Book class. Test your code with an array of 100 elements of Book. Call that array list (You canâ€™t have an array to store the BookstoreBook objects and another one to store the LibraryBook objects. One array (list) to hold all the book objects that your code creates).
