Number Array Class
Design a class that has an array of floating-point numbers. The constructor should accept an integer
argument and dynamically allocate the array to hold that many numbers. The private data members of
the class should include the integer argument in a variable to hold the size of the array and a
pointer to float type to hold the address of the first element in the array .
The destructor should free the memory held by the array .
In addition, there should be member functions to perform the following operations :
• Store a number in any element of the array
• Retrieve a number from any element of the array
• Return the highest value stored in the array
• Return the lowest value stored in the array
• Return the average of all the numbers stored in the array

Theatre seat booking - Java program
Part A
A new theatre company called ‘New Theatre’ has asked you to design and implement a new Java program to manage and control the seats that have been sold and the seats that are still available for one of their theatre sessions. They have provided you with their floorplan in which we can see that the theatre is composed of 3 rows, each with a different number of seats: 12, 16 and 20 retrospectively.
Task 1) Create a new project named Theatre with a class (file) called Theatre (Theatre.java) with a main method that displays the following message ‘Welcome to the New Theatre’ at the start of the program. Add 3 arrays (one for each row) in your program to keep record of the seats that have been sold and the seats that are still free. Row 1 has 12 seats, row 2 has 16 seats and row 3 has 20 seats. 0 indicates a free seat, 1 indicates an occupied (sold) seat. At the start of the program all seats should be 0 (free). This main method will be the method called when the program starts (entry point) for all Tasks described in this work.
Task 2) Add a menu in your main method. The menu should print the following 8 options: 1)Buy a ticket, 2) Print seating area, 3) Cancel ticket, 4) List available seats, 5) Save to file, 6) Load from file, 7) Print ticket information and total price, 8) Sort tickets by price, 0) Quit. Then, ask the user to select one of the options. Option ‘0’ should terminate the program without crashing or giving an error. The rest of the options will be implemented in the next tasks. Example:
-------------------------------------------------
Please select an option:
1) Buy a ticket
2) Print seating area
3) Cancel ticket
4) List available seats
5) Save to file
6) Load from file
7) Print ticket information and total price
8) Sort tickets by price
0) Quit
------------------------------------------------
Enter option:
Tip: Think carefully which control structure you will use to decide what to do after the user selects an option (Lecture Variables and Control Structures).
Task 3) Create a method called buy_ticket that asks the user to input a row number and a seat number. Check that the row and seat are correct and that the seat is available. Record the seat as occupied (as described in Task 1). Call this method when the user selects ‘1’ in the main menu.
Task 4)
A) Create a method called print_seating_area that shows the seats that have been sold, and the seats that are still available. Display available seats with the character ‘O’ and the sold seats with ‘X’. Call this method when the user selects ‘2’ in the main menu.
The output should show the following when no tickets have been bought:
OOOOOOOOOOOO
OOOOOOOOOOOOOOOO
OOOOOOOOOOOOOOOOOOOO
After purchasing a ticket for row 1, seat 6, and a ticket for row 3, seat 10, using option ‘1’ in the menu, the program should display the following:
OOOOOXOOOOOO
OOOOOOOOOOOOOOOO
OOOOOOOOOXOOOOOOOOOO
B) Update your code to align the display such that shows the seats in the correct location, and the stage, as shown below:
***********
* STAGE *
***********
OOOOOX OOOOOO
OOXXXXXX OOOOOXXX
XXOOOOXXXO XXXOOOXXXX
Task 5) Create a method called cancel_ticket that makes a seat available again. It should ask the user to input a row number and a seat number. Check that the row and seat are correct, and that the seat is not available. Record the seat as occupied (as described in
Task 1). Call this method when the user selects ‘3’ in the main menu.
Task 6) Create a method called show_available that for each of the 3 rows displays the seats that are still available. Call this method when the user selects ‘4’ in the main menu.
Example at the start of the program:
Enter option: 4
Seats available in row 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.
Seats available in row 2: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
Seats available in row 3: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.
Task 7) Create a method called save that saves the 3 arrays with the row’s information in a file. Call this method when the user selects ‘5’ in the main menu.
Task 8) Create a method called load that loads the file saved in Task 7 and restores the 3 arrays with the row’s information. Call this method when the user selects ‘6’ in the main menu.

for (int i = 0; i < ROWS; i++) {
What is the explanation of the above code?
The program manages and controls the seats sold and available for a theatre session.
It starts by displaying a welcome message and a menu with several options, including buying a ticket, printing the seating area, canceling a ticket, listing available seats, saving and loading from a file, and sorting tickets by price.
Each option is implemented as a separate method. The program keeps track of the seats that have been sold and the seats that are still available using three arrays, one for each row. It displays the seating area using 'X' for sold seats and 'O' for available seats, and includes the stage.
The program allows users to buy and cancel tickets, list available seats, and save/load data to/from a file.

Computer hardware refers to the physical components of a computer system that can be seen and touched. It encompasses all the tangible parts that make up a computer, enabling it to function and perform various tasks. Hardware includes devices such as the central processing unit (CPU), memory (RAM), storage devices (hard drives, solid-state drives), input devices (keyboard, mouse), output devices (monitor, printer), and other peripheral devices (speakers, scanners, etc.).
These hardware components work together to execute and manage data and instructions within a computer system. The CPU acts as the brain of the computer, performing calculations and executing instructions. Memory provides temporary storage for data and instructions that the CPU can quickly access. Storage devices store data in a more permanent manner, allowing it to be retained even when the computer is turned off.
Input devices enable users to input data and commands into the computer, while output devices display or present processed information to the user. Peripheral devices expand the capabilities of the computer system, providing additional functionalities and connectivity options.
Computer hardware is essential for the functioning of a computer and determines its processing power, storage capacity, and overall performance. It is complemented by software, which provides the instructions and programs necessary to utilize the hardware effectively. Together, hardware and software form the foundation of modern computer systems.

Hi!
i want to ask how to create this matrix A=[-4 2 1;2 -4 1;1 2 -4] using only eye ones and zeros .Thanks in advance!!
Answers
The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:
A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))
Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.
eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.
eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.
The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.
You can also create the matrix A by using following code:
A = [-4 2 1; 2 -4 1; 1 2 -4]
It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.

Does someone have the answers for 4.3.3 flying fish in cmu cs academy explore programming (cs0)? I'm stuck on it
Answers
The code you provided tells that the fish should be hooked when the mouse is close enough to the fish and below the water, with the following condition:
python
elif (mouseY > 300):
However, this condition alone may not be enough to properly hook the fish. You may need to adjust the condition or add additional conditions to ensure that the fish is being hooked correctly.
What is the Python code about?Based on the code you provided, it seems like you have implemented some restrictions for moving the fishing line and hooking the fish. If the fish is too far from the boat, you only move the fishing line. If the mouse is too far from the fish, you only move the line. If the mouse is close enough to the fish and below the water, the line should hook the fish.
However, it's hard to tell what specific issue you are facing without more context or a more detailed description of the problem. One thing to check is the values you are using to determine if the fish is close enough to be hooked. You mentioned that the horizontal distance between the mouse and the fish should be no more than 80, but your code checks if the mouse is less than 260. If this value is incorrect, it could be preventing the fish from being hooked.
Therefore, Another thing to check is the order in which you are updating the position of the fish and the fishing line
