WRITE IN C++

Create a class named Coord in C++

Class has 3 private data items

              int xCoord;

              int yCoord;

              int zCoord;

write the setters and getters. They should be inline functions

              void setXCoord(int)             void setYCoord(int)            void setZCoord(int)

              int getXCoord()                     int getYCoord()                   int getZCoord()

write a member function named void display() that displays the data items in the following format

     blank line

     xCoord is                          ????????

     yCoord is                          ????????

     zCoord is                          ????????

    Blank line

Example

     blank line

     xCoord is                          101

     yCoord is                          -234

     zCoord is                          10

Consider a disk drive with 2,000 tracks, numbered 0 to 1,999. The request queue has

the following composition: 1045 750 932 878 1365 1787 1245 664 1678 1897

The current position is 1167 and the previous request was served at 1250. For each

of the following disk scheduling algorithms, compute the total distance (in tracks)

that the disk arm would move. Explain how you arrive at your answers.

• Question #2 Write a program that prints a nicely formatted table of the product of every pair of numbers in a given set of integer numbers. Your program reads two integer numbers x and y that represent the lower and upper bounds of the set, (?≤?x≤y), respectively. Then, for every pair of numbers in this set {?,?+1,?+2,…,?}{x,x+1,x+2,…,y}, your program should compute the product of the two numbers.

• Please note the following:
  1. Your program should read each input (lower bound and the upper bound) one at a time, and should make sure that each input is an integer. If not, it should prompt the user to re-enter a valid input.
  2. Once the two numbers are read, your program should validate that the lower bound is less than or equal to the upper bound. Otherwise, the input should be read again, starting from the lower bound.

Case 6: Project Resource Management
Several people working on the Healthy You Intranet Project are confused about their responsibilities for the testing portion of the project. Recall that the team members include you, a programmer/analyst and junior/assistant project manager; Ivan, a network specialist; Helen, a business analyst; and Bonnie, another programmer/analyst. Paul Sparks is the project manager, and he has been working closely with managers in other departments to make sure everyone knows what’s going on with the project.
The main tasks for testing include writing a test plan, unit testing and integration testing for each of the main system modules (registration, tracking, and incentives), system testing, and user acceptance testing.
In addition to the project team members, a team of user representatives is available to help with testing, and Paul has also hired an outside consulting firm ABC Digital to help as needed.
One of the issues Paul identified is the ability to work effectively with the user group during testing. According to MBTI classifications, Paul knows that several of his project team members are very introverted and strong thinking types, while several members of the user group are very extroverted and strong feeling types.

Prepare a responsibility assignment matrix (RAM) based on the information from this case.
3. Prepare a RACI chart (use the template) to help clarify roles and responsibilities for these testing tasks. Document key assumptions you make in preparing the chart.

What is the basis of nonrepudiation and how is it commonly implemented? (Please be specific)

What does this mean in C++ syntax?

(leftover < 0 ? -leftover : 0)

and

(leftover > 0 ? leftover : 0)

Full version:

// rugfit1.cpp - calculates fit of rug to a floor

#include <iostream>
using namespace std;

// utility function to calculate area of a rectangle
double area(double width, double length) {
return width * length;
}

int main() {
  
double floorWidth, floorLength, rugWidth, rugLength,
floorArea, rugArea, leftover;

cout << "enter width and length of floor: ";
cin >> floorWidth >> floorLength;
cout << "enter width and length of rug: ";
cin >> rugWidth >> rugLength;

floorArea = area(floorWidth, floorLength);
rugArea = area(rugWidth, rugLength);
leftover = rugArea - floorArea;

cout << "floor area: " << floorArea << endl;
cout << "rug area: " << rugArea << endl;
cout << "leftover rug area: " <<
(leftover > 0 ? leftover : 0) << endl;
cout << "empty floor area: " <<
(leftover < 0 ? -leftover : 0) << endl;

return 0;

For this task, you will need to search for related literature to _nd your answer. You

must make use of the LNCS referencing style required here:

https://www:springer:com/gp/computer-science/lncs/conference-proceedings-

guidelines.

Look at the guidelines and the templates for reference examples. Failure to provide citations in LNCS style will result in mark forfeiture. You are also limited to use scientific material and books; websites like Wikipedia and StackOverflow are not considered a credible source.

5.1        What are the next developments that are proposed by researchers in the area              (1)

of RAID (not covered in the textbook)? Choose a particular development and

very briefly discuss it. Provide the necessary references for your answer.

USE JAVA PLEASE

Use recursion to implement a method

public static int indexOf(String text, String str)
that returns the starting position of the first substring of the text that matches str.

Return –1 if str is not a substring of the text.

For example, s.indexOf("Mississippi", "sip") returns 6.

Hint: You must keep track of how far the match is from the beginning of the text. Make that value a parameter variable of a helper method.

Questions

1. List one variable declaration and one constant declared in the code, along with the line number where you found the declaration. Why did the programmer declare it as a variable or constant?

2. What data types are referenced in the code on pages? For each data type, provide the line number of a declaration using that data type as well as the declaration itself. Additionally, list the primitive data types available in Java that are not referenced in the code.

3. Identify the different operators in the code, along with the line number where you found the operator example. Also identify the type of each operator listed as arithmetic, logical, relational, empty, or conditional.

4. Identify the control flow statements in the code. For each control flow statement, give the line number where you found the statement example. Also, list whether that statement is a decision-making, looping, or branching statement.

5. Identify the class definitions, object instantiations, and method calls in the code. Give the line number where you found each.

Below is a hypothetical example

Example: Class definitions

• Patient, line 22

• InsuranceCompany, line 49

• Physician, line 77 Object instantiations

• Alfred Smith, line 89

• Southwest HMO, line 95

• Dr. Smiley Jones, line 98 Method calls

• scheduleFollowUp(“Anne White”, “02/08/19”, “12:45”), line 124

• remitBill(“George Torres”, 33535), line 155

• referPatient(“Bob Allen”), line 189

Assume a linear model and then add 0-mean Gaussian noise to generate a sample. Divide your sample into two as training and validation sets.

Use linear regression using the training half. Compute error on the validation set. Do the same for polynomials of degrees 2 and 3 as well
