I need to be able to store 5000 names into an array. I currently have a code that generates one random name. I just need to generate an array of 5000 the same way.

#include <cstdlib>
#include <ctime>
#include <iostream>
#include <iomanip>

using namespace std;

string RandomFirstGen(int namelength);

int main(){

srand(time(NULL));
int namelength = rand()%(16-8+1)+8;
cout<<"name is: "<<RandomFirstGen(namelength)<<endl;

return 0;
}

string RandomFirstGen(int namelength){
for (int i=0; i<=5000 ; i++){
const int MAX = 26;
char alphabet[MAX] = {
'a', 'b', 'c', 'd', 'e', 'f', 'g',
'h', 'i', 'j', 'k', 'l', 'm', 'n',
'o', 'p', 'q', 'r', 's', 't', 'u',
'v', 'w', 'x', 'y', 'z'};
string name = "";
for (int i = 0; i < namelength; i++)
name = name + alphabet[rand() % MAX];

The following is a chart of 25 baseball players' salaries and statistics from 2016.

In order to have correlation with 95% significance, what is the critical r-value that we would like to have?  

(Round to three decimal places for all answers on this assignment.)

RBI vs. Salary

Complete a correlation analysis, using RBI's as the x-value and salary as the y-value.

Correlation coefficient:

Regression Equation: y=y=    

Do you have significant correlation? Select an answer Yes No

HR vs. Salary

Complete a correlation analysis, using HR's as the x-value and salary as the y-value.

Correlation coefficient:

Regression Equation: y=y=       

Do you have significant correlation? Select an answer Yes No   

AVG vs. Salary

Complete a correlation analysis, using AVG as the x-value and salary as the y-value.

Correlation coefficient:   

Regression Equation: y=y=       

Do you have significant correlation? Select an answer Yes No

Prediction

Based on your analysis, if you had to predict a player's salary, which method would be the best? Select an answer Regression equation with RBI's Regression equation with HR's Regression equation with AVG The average of the 25 salaries

Using that method, predict the salary for Ryan Braun. His stats were:

RBI: 91

HR: 31

AVG: 0.305

Based on your analysis, his predicted salary would be: $ million  

His actual salary was $20.000 million.

Improve class OurLinkedList, so that its users can readily access a list's middle node. Readily here means that when users instantiate an OurLinkedList object, they can access the node in the middle of the list without starting from the head, counting how many nodes to the end, then going back to the head, and skipping half as many nodes forward. In fact, there should be no counting for this improvement. Notice that lists with an even number of nodes, do not have a well defined middle node and it is up to you to determine which node near the middle will be considered the middle one.

Your improvement must be delivered only in the form of a new class that extends OurLinkedList. Name the extending class, after yourself, as following:

class YourfirstnameLinkedList extends OurLinkedList { ... }

replacing Yourfirstname above, with your actual first name (e.g., MyLinkedList).

SOURCE CODE FOR QUESTION

public class OurLinkedList {

class Node {
  
String value;
Node next;
  
Node(String v) {
value = v;
next = null;
} // constructor Node
} // class Node

/**
* Accessor for the field size.
* @return number of nodes in the list.
*/
public int getSize() {
return size;
} // method getSize

  
public boolean nodeExists(String v) {
// Initial assumption: no node found with string v
boolean stringFound = false;
// Start from the beginning.
Node currentNode = head;
if ( currentNode == null) {
// Empty list.
stringFound = false;
} else {
// List is not empty. Let's check if the last node contains
// string we are looking for. We do this here, because the
// last node is unreachable in a loop that terminates when
// .next == null.
stringFound = tail.value == v;
// Search through the rest of the linked list, hopping from
// node to node, following the .next pointer.
while (currentNode.next != null) {
if ( currentNode.value == v) {
stringFound = true;
}
currentNode = currentNode.next;
}
}
return stringFound;
} // method nodeExists

public void addNode(String v) {
if (!nodeExists(v)) {
// The list does not contain a node with the given string.
// Let's create one and call it newNode.
Node newNode = new Node(v);
// We are adding this newNode to the list, so let's increase the size.
size++;
// Now we need to determine where to add this new node.
if (head == null) {
// List is empty. Make this newNode the list's head.
head = new Node(v);
// Because the list is empty, make this node its tail as well.
tail = head;
} else {
// The list is not empty. Find its tail node and add the
// newNode after it.
tail.next = newNode;
// Make the newNode, the list's new tail.
tail = newNode;
}
}

public boolean remove(String v) {
boolean success = false;

success = true;

return success;
}

class MyLinkedList extends OurLinked {...}

public static void main(String[] args) {
OurLinkedList demo = new OurLinkedList();
}

}

The question wants us to find the middle of the list immediately without traversing the linked list conventionally but any help is great. There is no need to print the list just to know where the middle of the list is.

10.8 LAB*: Program: Data visualization

(1) Prompt the user for a title for data. Output the title. (1 pt)

Ex:

Enter a title for the data:
Number of Novels Authored
You entered: Number of Novels Authored

(2) Prompt the user for the headers of two columns of a table. Output the column headers. (1 pt)

Ex:

Enter the column 1 header:
Author name
You entered: Author name

Enter the column 2 header:
Number of novels
You entered: Number of novels

(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in an ArrayList of strings. Store the integer components of the data points in a second ArrayList of integers. (4 pts)

Ex:

Enter a data point (-1 to stop input):
Jane Austen, 6
Data string: Jane Austen
Data integer: 6

(4) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message and prompt again for a valid data point.

• If entry has no comma
  • Output: Error: No comma in string. (1 pt)
• If entry has more than one comma
  • Output: Error: Too many commas in input. (1 pt)
• If entry after the comma is not an integer
  • Output: Error: Comma not followed by an integer. (2 pts)

Ex:

Enter a data point (-1 to stop input):
