hello! So I have this CIS assignment lab but when I try to make the code I don't really know where to start from. My professor is very hard and he likes to see the outcomes as they are shown in the problem. Please help me! the program should be a C++ PLS

Write a program that can be used as a math helper for an elementary student. The program should display two random integer numbers that are to be added, such as:
    247
+ 129
-------

The program should wait for the students to enter the answer. If the answer is correct, a message of congratulations should be printed. If the answer is incorrect, a message should be printed showing the correct answer.

The program displays a menu allowing the user to select an addition, subtraction, multiplication, or division problem. The final selection on the menu should let the user quit the program. After the user has finished the math problem, the program should display the menu again. This process is repeated until the user chooses to quit the program.
Input Validation: If the user select an item not on the menu, display an error message and display the menu again.

Requirements:

Addition
Generate two random numbers in the range 0 - 9.

Subtraction

Generate two random numbers in the range 0 - 9.
num1 = rand() % 10;
num2 = rand() % 10;
Make sure num2 <= num1...
while (num2 > num1)
num2 = rand() % 10;

Multiplication

Generate two random numbers. The first in the range 0 - 10, the second in the range 0 - 9.

Division

Generate a single digit divisor
num2 = rand() % 9;
Generate a num1 that is a multiple of num2 so the division has no remainder. The num1 is never zero.
num1 = num2 * (rand() % 10 + 1);

All constant values must be declare as a constant variable. Use the constant variable in the calculation.
Validating the selection (1 to 5). If the selection is not in the range between 1 and 5, the program keeps asking the input until the correct selection is entered.
Comments in your program to explain the code logic and calculation.

"Thank you for using math helper!"

Consider a set of n boxes with their positions numbered from 1 to n. Initially all the boxes
are CLOSED. These n boxes are subject to modifications over n iterations as follows. At the ith
iterations the boxes at the positions whose ids are multiples of i are flipped, i.e. changed from
CLOSED to OPEN or vice-versa. For example, at iteration 1, boxes at all positions are
flipped, at iteration 2, boxes at positions 2,4,6,etc. are flipped, at iteration 3, boxes at positions 3,6,9, etc.
are flipped.
Propose an algorithm for find out, that after n such iterations how many boxes will be OPEN.
Note that the answer requires only how many boxes, not their positions. Describe the rationale
for the algorithm, give the pseudocode, and its complexity. Grading scheme: (your grade will be
based on whichever class your algorithm falls in)
- For algorithms with complexity O(kn), where k is the number of digits of n.

Write a program that

          - a user-defined class Cuboid which has the following elements:

                   - default constructor (has no parameters)

                   - constructor that has 3 parameters (height, length, width)

                   - data members

                             - height, length, width

                   - member functions

                             - to set the value of each of the data members - 3 functions

                             - to get the value of each of the data members - 3 functions

                             - one that returns the volume

                             - one that returns the surface area

                             - one that increases each dimension by a specified factor

                   (Function definitions outside of the class!!!)

          - in main()

                   - instantiate a Cuboid object and initialize at the time of definition

                             - make sure the constructor with parameters is called

                      - define an array of 2 Cuboid objects

                      - using a loop get information to populate the 2 objects in the array

                               -prompt for the height, length, and width

                                -prompt for a size by which to increase each dimension(one input)

      -call a global function passing a Cuboid object and the increase factor as separate arguments; function will call the class member function to increase the dimensions; parameters of the function should be references

                  -display the dimensions, the volume, and the surface area for each of the three objects.

Given the array b = np.arange(-6, 4) compute and print

1.) The array formed by \(bi^2 - 1\), where the \(bi\) are the elements of the array b.

2.) The array formed by multiplying b with the scalar 100.

3.)The array formed by 2.0 b i in reverse order. (Note: the base 2.0 must be a floating point number; for integer values a ValueError: Integers to negative integer powers are not allowed. is raised.)

4.) The array delta of length len(b)-1 that contains the differences between subsequence entries of \(bi^3\), namely \(\deltai = b{i+1}^3 - bi^3 \) with 0 ≤ i < N − 1 where N is the length of b. Print both delta.shape and delta.

Modeling multiprogramming: (a) Assume the I/O fraction time of all processes is 20%, and assume processes are independent from each other, what’s the CPU utilization, if the number of processes, n = 1, 2, 4, and 8, respectively? (b) If the I/O fraction time is 50% for all processes, what’s the CPU utilization again, if the number of processes, n = 1, 2, 4, and 8, respectively?

Project on a double pendulum using MATLAB. I have simulated double pendulum chaos using the code I found in Chegg. Could you please guide in adding a code to determine the time it takes for the second arm of the pendulum to "flip" based on initial starting conditions?

List at least six reasons of why mobile apps are essential and preferable than traditional websites for everyday business

Do the following: • Download Wireshark. • Start Wireshark. • Turn on Wireshark capture. • Type a URL in your browser window (not Wikipedia.org). • After a few seconds, stop the capture. • Answer the following questions: 1a. What URL did you use? What was the IP address of the webserver?

1b. Find the frame in which your PC sent the SYN packet. List the source and destination IP address, the source and destination port numbers, and the header checksum.

1c. Select the SYN/ACK packet. List the source and destination IP address, the source and destination port numbers, and the header checksum.

1d. Select the packet that acknowledges the SYN/ACK segment. List the source and destination IP address, the source and destination port numbers, and the header checksum. 2. Change the options so that only packets you send are recorded. Do a capture. Click on the window containing Wireshark and hit Alt-Enter. This captures the window to your clipboard. Paste it into your homework.

In Unity with C#, I need to implement a dice simulator in my character generator(D&D). I have 6 sides of UI images(2D). With my code, I am able to roll and get the number in my console text(randomly).

But, I need help for rolling 5 dices, not the 1 dice. Also, I need to add all the three highest rolls with 5 dices and get a result in my display.

Ex) 1. Players must roll 5d6 and add the three highest rolls to compute each of the six Abilities. Note make all modifiers default to +2.

Write a program that:

1. Declares a variable suitable for holding a person’s name
2. Prompts the user to enter a person’s name with the text Enter name:
3. Reads the user's input and stores it in the variable created in step 1
4. Outputs the following information about the name they entered
   a. The index of the last character in the name
   b. The last 3 characters of the first name
   c. The first 3 characters of the last name
   Your output should look like the examples below. **Note: Your code should account for the fact that the user might enter a middle name or initial.

Example 1:

Enter name: Grace Hopper
Index of last character: 11
Last 3 characters of first name: ace
First 3 characters of last name: Hop

Example 2:

Enter name: Dorothy J. Vaughan
Index of last character: 17
Last 3 characters of first name: thy
First 3 characters of last name: Vau

This is my code:

#include <iostream>
#include <string>
using namespace std;

int main()
{
   string userFirstname;
   string userLastname;
   string userMiddlename;

   cout << "Enter Name: ";
   cin >> userFirstname;
   cin >> userMiddlename;
   cin >> userLastname;
   cout << userFirstname << userMiddlename << userLastname << endl;

   cout << "Index of last character: ";
   cout << ((userFirstname.size() + userLastname.size()) - 1);
   cout << endl;

   cout << "Last 3 characters of first name: ";
   cout << (userFirstname.at(userFirstname.size() - 3)) << (userFirstname.at(userFirstname.size() - 2)) << (userFirstname.at(userFirstname.size() - 1)) << endl;

   cout << "First 3 characters of last name: ";
   cout << userLastname.at(1) << userLastname.at(2) << userLastname.at(3) << endl;

   return 0;
}

Create a Java to find the GCD of two numbers. You will need to create a new variable to reflect the algorithm (numberOne, numberTwo, GCD = 0).

Requirements:

1) read in numberOne

2) read in numberTwo.

3) run the loop, If numberTwo is 0 then print out numberOne, otherwise, temp =numberOne % numberTwo, numberOne = numberTwo, numberTwo = temp.
