Create a C++ console application to store points for contestants in a contest. Ask the user for the number of contestants. Create two parallel dynamic arrays, one to store the names and one to store integer scores from zero to 100. Do not accept out of range numbers. Ask the user for each name and the score one at a time.
When you encounter the end of the array, print all names and scores. Also, print the average and indicate whether each score is above or below average. The example is attached in the file and I want you to get the same output on the shown display of the program.
Requirements:
1 Add comments as you code. Do NOT wait until you are done coding. Also, in the beginning of your codes include the following comments:
Purpose of the program,
Name of the author, and
Date
2 Tell the user what the program is all about.
3 Create a function to get the values from the user and store them in the arrays. Pass the pointers and array size to the function. This function will have a void return type.
4 Create a function to calculate the average. Pass a pointer and the size to the array. The function should return the average.
5 Create another function to print the result. Pass the pointers, the array size, and the average to the function.
6 Do not pass arrays to functions. Even though it is possible to do so, we are trying to practice using pointers.
7 All functions will be called only by the main. Prevent calling them by other functions.
8 No global variables are allowed.
9 Delete the arrays to free the memory after printing the results.
10 Ask the user if they want to continue. If so, ask the questions again.
11 Test, test, and test.
Hints:
Please, do NOT use 'break' or 'continue' in the code.
This is how you create a dynamic array: arrayPtr = new int[size];
Use this syntax to pass the pointer to a function: void display (string* namePtr){ }

self.year_made = 0
#year car was made is initialized to 0 (integer)
self.car_vin = ' '
#vehicle registration is an empty string
def __str__(self):
#define an str method
return f"Year:{self.year_made}, VIN:{self.car_vin}"
#returns formatted display of the year and VIN number
my_car = CarRecord()
#creates an instance of the carRecord class

Consider a Stop-and-Wait protocol. Assume constant delays for all transmissions and the same delay for packets sent and ACKs sent. Assume no errors occur during transmission.
(a) Suppose that the timeout value is set to 1/2 of what is required to receive an acknowledgement, from the time a packet is sent. Give the complete sequence of frame exchanges when the sender has 3 frames to send to the receiver.
(b) Suppose that the timeout value is sent to 2 times the round trip time. Give the sequence of frame exchanges when 3 frames are sent but the first frame is lost.
Answers
Explanation:
question a) answer:
At the moment when it sends the package, then it has a waiting time for the acknowledgement from the receiver, however, the time will be split in two when the frameset size becomes two, meaning that two packages have been sent together, causing the receiver to acknowledge only one package.
question b) answer:
The timeout is equal to two times.
In cases when the frame size is 3, the frame will be lost since the timeout turns to be 2 times. Because the sender has to wait for the acknowledgement, therefore it will send other of the parcels.

Write a program whose inputs are three integers, and whose output is the smallest of the three values. Use else-if selection and comparative operators such as '<=' or '>=' to evaluate the number that is the smallest value. If one or more values are the same and the lowest value your program should be able to report the lowest value correctly. Don't forget to first scanf in the users input.
Ex: If the input is: 7 15 3
the output is: 3
You should sketch out a simple flowchart to help you understand the conditions and the evaluations needed to determine what number is the correct answer. This type of tool can help determine flaws in a logical design.
Answers
Answer:
The Program written in C is as follows:
#include <stdio.h>
int main() {
int num1, num2, num3, smallest;
printf("Enter any three numbers: ");
scanf("%d", &num1); scanf("%d", &num2); scanf("%d", &num3);
if(num1 <= num2 && num1 <= num3) {
smallest = num1;
}
else if(num2 <= num1 && num2 <= num3) {
smallest = num2;
}
else {
smallest = num3;
}
printf("Smallest: ");
printf("%d", num3);
return 0;
}
Explanation:
This line declares necessary variables
int num1, num2, num3, smallest;
This line prompts user for input of three numbers
printf("Enter any three numbers: ");
This lines get input for the three numbers
scanf("%d", &num1); scanf("%d", &num2); scanf("%d", &num3);
The following if/else statements determine the smallest of num1, num2 and num3 and assigns to variable smallest, afterwards
if(num1 <= num2 && num1 <= num3) {
smallest = num1;
}
else if(num2 <= num1 && num2 <= num3) {
smallest = num2;
}
else {
smallest = num3;
}
The next two lines print the smallest value
printf("Smallest: ");
printf("%d", num3);

The growth of smartphone production and smartphone apps and services, as well as the production of smartphones, has had a positive influence on the IT industry, IT practitioners, as well as the development of the technology. As normal, the primary focus is on smartphone apps instead of just desktop software. As we recognize, with innovative features, phone applications, and smartphones are all made, built, modernized every day, and always incorporated with either the latest technology.This has now resulted in far more jobs and employment for the IT sector, and therefore new clients for service-based businesses. It provided various-skilling the application production industry for IT experts including learning how to work on emerging technology. The demand for software production and software growth is evolving at a greater speed than it's ever been, so the increase of smartphone production and smartphones has had a very beneficial effect on perhaps the IT sector, IT practitioners, and business development.(1) Prompt the user to enter a string of their choosing. Output the string.

Explanation:
import java.util.*;
class Main {
public static void main(String[] args) {
//PrompT the User to enter a String
System.out.println("Enter a sentence or phrase: ");
//Receiving the string entered with the Scanner Object
Scanner input = new Scanner (System.in);
String string_input = input.nextLine();
//Print out string entered by user
System.out.println("You entered: "+string_input);
//Call the first method (GetNumOfCharacters)
System.out.println("Number of characters: "+ GetNumOfCharacters(string_input));
//Call the second method (OutputWithoutWhitespace)
System.out.println("String with no whitespace: "+OutputWithoutWhitespace(string_input));
}
//Create the method GetNumOfCharacters
public static int GetNumOfCharacters (String word) {
//Variable to hold number of characters
int noOfCharactersCount = 0;
//Use a for loop to iterate the entire string
for(int i = 0; i< word.length(); i++){
//Increase th number of characters each time
noOfCharactersCount++;
}
return noOfCharactersCount;
}
//Creating the OutputWithoutWhitespace() method
//This method will remove all tabs and spaces from the original string
public static String OutputWithoutWhitespace(String word){
//Use the replaceAll all method of strings to replace all whitespaces
String stringWithoutWhiteSpace = word.replaceAll(" ","");
return stringWithoutWhiteSpace;
}
}

4 beeps indicate a Memory Read / Write failure. Try re-seating the Memory module by removing and reinserting it in the slot. This could mean it could've just jiggled loose after a while or dust, there could be a hundred other problems but those are the two most common.n

Given four values representing counts of quarters, dimes, nickels and pennies, output the total amount as dollars and cents. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("Amount: $%.2f\n", dollars); Ex: If the input is: 4 3 2 1 where 4 is the number of quarters, 3 is the number of dimes, 2 is the number of nickels, and 1 is the number of pennies, the output is: Amount: $1.41 For simplicity, assume input is non-negative.

Adjust list by normalizing When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one.

WILL GIVE BRAINLYIEST 3pts) Make a prediction about which material will be the best insulator and conductor of heat. Materials: aluminum, glass, fiber glass, air between glass, and brick:
a. I think the _____________ will conduct heat better.
b. I think the _____________ will insulate heat better.
Answers
Answer:
a. I think the Aluminum will conduct heat better.
b. I think the Fiberglass will insulate heat better.
Fiberglass is used to insulate most everyday items, so I can be sure that fiberglass can be the best insulator, as for aluminum it conducts heat like you wouldn't believe.
Note: Your answer doesn't have to be right, they just want you to make a prediction about your answer, that means it's alright to guess, also know I didn't guess I am just telling you that you didn't have to ask this question. <3
You have been given two classes, a Main.java and a Coin.java. The coin class represents a coin. Any object made from it will have a 1) name, 2) weight and 3) value. As of now, the instance variables in Coin.java are all public, and the main function is calling these variables directly for the one coin made in it.
Required:
Your goal is to enforce information hiding principles in this tasl. Take Coin.java, make all instance variables private and create set/get functions for each instance variable. Then replace the direct references in main() to each instance variable with a call to an appropriate set or get function.
Answers
Answer:
Here is the Coin class:
public class Coin { //class names
private int value; // private member variable of type int of class Coin to store the value
private String coinName; // private member variable of type String of class Coin to store the coint name
private double weight; //private member variable of type double of class Coin to store the weight
public void setValue (int v) { //mutator method to set the value field
value = v; }
public void setName(String n){ //mutator method to set coinName field
coinName = n;}
public void setWeight (double w) { //mutator method to set weight field
weight = w; }
public int getValue () { //accessor method to get the value
return value; } // returns the current value
public String getName () { //accessor method to get the coin name
return coinName; } //returns the current coin name
public double getWeight () { //accessor method to get the weight
return weight; } } //returns the current weight
Explanation:
Here is the Main.java
public class Main{ //class name
public static void main(String[] args) { //start of main method
Coin penny = new Coin(); //creates object of Coin class called penny
penny.setName("Penny"); //calls setName method of Coin using object penny to set the coinName to Penny
penny.setValue(1); //calls setValue method of Coin using object penny to set the coin value to 1
penny.setWeight(0.003); //calls setWeight method of Coin using object penny to set the coin weight to 0.003
System.out.println("Coin name: " + penny.getName()); // calls getName method of Coin using penny object to get the current coin name stored in coinName field
System.out.println("Coin value: " + penny.getValue()); // calls getValue method of Coin using penny object to get the coin value stored in value field
System.out.println("Coin weight: " +penny.getWeight()); }} // calls getWeight method of Coin using penny object to get the coin weight stored in weight field
The value of coinName is set to Penny, that of value is set to 1 and that of weight is set to 0.003 using mutator method and then the accessor methods to access these values and prinln() to display these accessed values on output screen. Hence the output of the entire program is:
Coin name: Penny Coin value: 1 Coin weight: 0.003
The screenshot of the program along with its output is attached.
