Rewrite the function so the formal parameter x is an IO pointer-to int parameter. The function’s prototype is changed as shown below. Please explain code with comments

//--------------------------------------------------

void NextPrime(int *x)

//--------------------------------------------------

{

bool IsPrime(const int x);

}

Compare PHP code used to create and update two-dimensional arrays to another programming language. Which is easier and more efficient? Why? Can be compared to any other well used language.

Assignment 3-4: IN PYTHON

Guest List: If you could invite anyone to dinner, who would you invite? Make a list that includes at least three people you’d like to invite to dinner. Then use your list to print a message to each person, inviting them to dinner.

---------------------------------------------------------------

Assignment 3-5:

Changing Guest List: You just heard that one of your guests can’t make the dinner, so you need to send out a new set of invitations. You’ll have to think of someone else to invite.

• Start with your program from Assignment 3-4. Add a print statement at the end of your program stating the name of the guest who can’t make it.
• Modify your list, replacing the name of the guest who can’t make it with the name of the new person you are inviting.
• Print a second set of invitation messages, one for each person who is still in your list.

---------------------------------------------------------------

Assignment 3-6:

More Guests: You just found a bigger dinner table, so now more space is available. Think of three more guests to invite to dinner.

• Start with your program from Assignment 3-4 or Assignment 3-5. Add a print statement to the end of your program informing people that you found a bigger dinner table.
• Use insert() to add one new guest to the beginning of your list.
• Use insert() to add one new guest to the middle of your list.
• Use append() to add one new guest to the end of your list.
• Print a new set of invitation messages, one for each person in your list.

---------------------------------------------------------------

Assignment 3-7:

Shrinking Guest List: You just found out that your new dinner table won’t arrive in time for the dinner, and you have space for only two guests.

• Start with your program from Assignment 3-6. Add a new line that prints a message saying that you can invite only two people for dinner.
• Use pop() to remove guests from your list one at a time until only two names remain in your list. Each time you pop a name from your list, print a message to that person letting them know you’re sorry you can’t invite them to dinner.
• Print a message to each of the two people still on your list, letting them know they’re still invited.
• Use del to remove the last two names from your list, so you have an empty list. Print your list to make sure you actually have an empty list at the end of your program.

Instructions

Create a program to keep track of the statistics for a kid’s soccer team. The program will have a structure that defines what data the program will collect for each of the players. The structure will keep the following data:

Players Name (string)

Players Jersey Number (integer)

Points scored by Player (integer)

The program will have an array of 12 players (use less for testing and development, use a constant for the size). Each element in the array is a different player on the team.

The program will ask the user to enter information for each player. The program will also display the team information in a table format. After the table, the total points scored by a team will be displayed.

The program will also determine which player scored the most points on the team.

Validation:

Do not accept negative value for player’s number

Do not accept negative value for player’s score

Required Methods:

void GetPlayerInfo(Player &);

void ShowPlayerInfo(const Player);

int GetTotalPoints(const Player[ ], int);

void ShowHighest(Player [ ], int)

In-House, IaaS, or SaaS?

Your organization's current email system is hosted on-premise in a old server that is reaching its end-of-life. Your boss has asked you to replace the existing system

Your boss wants you to research the various options for a new system and is open to hosting it in-house, in the cloud, as a service, or any other solution you may find

Your task:

• Research the options available for hosting your organizations email
• Identify a preferred solution
• Explain to your boss in an email (i.e. response) why this solution is preferable.

Write a python program to display a menu with the following options: (1) add, (2) subtract, (3) multiply, (4) divide (5) mod, and (6) do nothing. I

f the user enters something else (except 1-6), the program should display an error message.

Otherwise, it should ask the user for two numbers, perform the calculation, and display the result.

In Java

Problem 1
Create an Array of your top four vacation spots. Print the first spot and the last spot in your array.

Problem 2
Create an Array to hold the names of 5 people. Print the first letter of each of their names.

Problem 3
Create a mini console game that asks for the number of words you want to enter into an Array. Enter each word and then a letter. Print out feedback that says "Yep its got one of those" or "Sorry that letter is not in the word" depending on whether on not the word entered contains the letter specified.

Stretch Task (Optional)
Create a String representing a list of things that uses some delimiter (commas,dashes, etc) Split that String into an Array of Strings, then print each of the Array Elements. You will need to research (How to Split a String using a Delimiter).

Write a Java program in Eclipse to calculate the total cost to enter into a waterpark for a family/group

Ticket rates are listed below

kids (Age 12 and under)=$ 12.50

Regular( Age between12 -55) =$ 18.25

Seniors (55 and above) = $15.00

Tax =7%

Your program should ask the user to enter the total number of members in their group.

User needs to enter the ages for all members. Write appropriate error messages for invalid entries.

An array should be used to store the ages of the family members.

Based on the age it has to calculate the cost of each member and calculate the total cost including tax.

Your program should display

The number of tickets for each type

And the total cost for the group

After display your program should repeat the process until the user wants to stop.

Your program must use

1. Array
2. Do while Loop
3. Constant variable
4. Atleast one method

Sample run of the program:

Welcome to our WATERPARK!!!

Please enter the number of members in your group.   7

Please enter the ages for each person in your group. 15 28 11 34 26 60 58

Please pay the total of $115.50 + 7% tax = $ 123.59

And pick up

1 Kid ticket

4 Regular tickets and

2 Senior tickets

Please Press a positive number for next customer, Negative number to end. 5

Welcome to our WATERPARK!!!

Please enter the number of members in your group.  

Program 3: Give a baby $5,000!  Did you know that, over the last century, the stock market has returned an average of 10%?  You may not care, but you’d better pay attention to this one.  If you were to give a newborn baby $5000, put that money in the stock market and NOT add any additional money per year, that money would grow to over $2.9 million by the time that baby is ready for retirement (67 years)!  Don’t believe us?  Check out the compound interest calculator from MoneyChimp and plug in the numbers!

To keep things simple, we’ll calculate interest in a simple way.  You take the original amount (called the principle) and add back in a percentage rate of growth (called the interest rate) at the end of the year.  For example, if we had $1,000 as our principle and had a 10% rate of growth, the next year we would have $1,100.  The year after that, we would have $1,210 (or $1,100 plus 10% of $1,100).  However, we usually add in additional money each year which, for simplicity, is included before calculating the interest.

Your task is to design (pseudocode) and implement (source) for a program that 1) reads in the principle, additional annual money, years to grow, and interest rate from the user, and 2) print out how much money they have each year.  Task 3: think about when you earn the most money! Lesson learned: whether it’s your code or your money, save early and save often…

Sample run 1:

Enter the principle: 2000

Enter the annual addition: 300

Enter the number of years to grow: 10

Enter the interest rate as a percentage: 10

Year 0: $2000

Year 1: $2530

Year 2: $3113

Year 3: $3754.3

Year 4: $4459.73

Year 5: $5235.7

Year 6: $6089.27

Year 7: $7028.2

Year 8: $8061.02

Year 9: $9197.12

Year 10: $10446.8

Sample run 2 (yeah, that’s $9.4MM):

Enter the principle: 5000

Enter the annual addition: 1000

Enter the number of years to grow: 67

Enter the interest rate as a percentage: 10

Year 0: $5000

Year 1: $6600

Year 2: $8360

Year 3: $10296

Year 4: $12425.6

Year 5: $14768.2

////////////( PLEASE WRITE IN PSEUDOCODE )/////////////////

C++ Parse text (with delimiter) read from file.

If a Text file has input formatted such as: "name,23" on every line where a comma is the delimiter, how would I separate the string "name" and integer "23" and set them to separate variables for every input of the text file? I am trying to set a name and age to an object and insert it into a vector.

#include <iostream>
#include <vector>
#include <fstream>
using namespace std;

class Student{
    public:
        string name;
        int age;
};

int main() {

    vector <Student>studentVector;
    Student s;
    string student_name;
    int student_age;
  
    ifstream myFile("file.txt");
      
    while(myFile>> student_name >> student_age){

        //s.name is assigning the entire line of unparsed text
        s.name = student_name;

       ///age is not read because input string from file is not parsed

        s.age = student_age;

        studentVector.push_back(s);
    }

    return 0;
}

Code: please use in visual studio 2019 c++ (not java)

In total you will write 6 functions:

Functions :

A ) addInts, returns int; input is two ints; Add the values of the two parameters and return the sum

B) subInts , returns int; input is two ints; Subtract the values of the two parameters and return the difference

C) multInts, returns int; input is two ints; multiple the values of the two parameters and return the product

D) divInts, returns int; input is two ints; Divide the values of the two parameters and return the quotient

E) modInts, returns int; input is two ints; compute the residual of the values of the two parameters and return the residual

F) A function called computeOperation ( ) that , returns an int; input is three parameters: one 'control' int, and two ints;  

if the control int ( the first parameter) is :

Control

expect to see both Function Declarations and of course the Function Definitions for all 6 functions

expect to see some obvious test code or data sets.  

expect to see a switch statement not a series of if statements if it is appropriate.

To Be Clear:

in the main function there should be a homework header and then a bunch of 'call's to the

computeOperation ( ) function.  

And

computeOperation should then have code to invoke one of the 5 low level compute functions. The value that is returned should be returned by computeOperator.

Find the statistics for a single quantitative variable by utilizing Encapsulation and Namespace functions:

Each function should accept a list as an input parameter:

List = [1,2,3,4,5,6]

Functions : lst_min, lst_max, lst_range, lst_variance, lst_stdev.

Use: Python programming language, please. (Note: without inbuilt function)

Thank you.

Are Gradient boosting model, Random Forest, XGBoost, and LightGBM all tree-based models??

Thanks!
