Checking the age of that the user has passed as an input and changing the variables as needed depending on the age. The background color that was changed was for the form field as the question was not very specific on which field needed to be changed. The piece of the code that was created can be seen in the attached image below.
var validColor = "LightGreen";
var invalidColor = "Orange";
var userAgeInput = document.getElementById("userAge");
var formWidget = document.getElementById("userForm");
var userAgeValid = false;
function userAgeCheck(event) {

Briefly explain what an array is. As part of your answer make use of a labelled example to show the declaration and components of an array
Answers
Answer:
Explanation:
In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...
int[] myArray = {33, 64, 73, 11, 13};
In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}

3. When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested?
A. Series
B. Parallel
C. Control
D. Line
Answers
Answer:
B. Parallel
Explanation:
When using the ohmmeter function of a digital multimeter, the leads are placed parallel to the component being tested. The digital multimeter is placed parallel to the component because, current has to flow into the component so as to be able to measure its resistance. Without the flow of current in the component, the resistance could not be measured.
If the component were placed in series, there would be no way to close the circuit because, we need a closed circuit so as to measure the resistance and use the ohmmeter function of the digital multimeter.
Only a parallel connection would close the circuit.
So, B is the answer.
Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.
Answers
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> intVect;
int n;
cin>>n;
int intInp;
for (int i = 0; i < n; i++) {
cin >> intInp;
intVect.push_back(intInp); }
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }
return 0;
}
Explanation:
This declares the vector
vector<int> intVect;
This declares n as integer; which represents the number of inputs
int n;
This gets input for n
cin>>n;
This declares intInp as integer; it is used to get input to the vector
int intInp;
This iterates from 0 to n-1
for (int i = 0; i < n; i++) {
This gets each input
cin >> intInp;
This passes the input to the vector
intVect.push_back(intInp); }
This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse
for (int i = n-1; i >=0; i--) { cout << intVect[i] << " "; }

Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect. Submit the code of the program and your comments on the execution of the program.
Answers
Answer:
Following are the code to the given question:
import java.util.concurrent.*; //import package
public class Threads //defining a class Threads
{
private Integer s = new Integer(0);//defining Integer class object
public synchronized static void main(String[] args)//defining main method
{
Threads t = new Threads();//defining threads class object
System.out.println("What is sum ?" + t.s);//print value with message
}
Threads()//defining default constructor
{
ExecutorService exe = Executors.newFixedThreadPool(1000);//defining ExecutorService class object
System.out.println("With SYNCHRONIZATION........");//print message
for(int i = 1; i <= 1000; i++)//defining a for loop
{
exe.execute(new SumTask2());//calling execute method
System.out.println("At Thread " + i +" Sum= " + s + " , ");//print message with value

int value = s.intValue() + 1;//defining variable value that calls intvalue which is increment by 1

Output:
Please find the attached file.
Explanation:
In this code, a Threads class is defined in which an integer class object and the main method is declared that creates the Threads class object and calls its values.
Outside the method, the default constructor is declared that creates the "ExecutorService" and prints its message, and use a for loop that calls execute method which prints its value with the message.
In the class, a while loop is declared that calls "isTerminated" method, and outside the class "SumTask2" that inherits Runnable class and defined the run method and define a variable "value" that calls "intvalue" method which is increment by 1 and define s variable that holds method value.

Databases on related subjects that you want to integrate may have different numbers of columns or rows. An attribute named 'weight' may be in different units in different databases. There may be discrepancies between entries in two different databases for the same actual real-life entity (e.g. for an employee).

Two different databases may have different column names for the same actual information (e.g. customer ID vs customer-id).
There may be discrepancies between entries in two different databases for the same actual real-life entity (e.g. for an employee).
Explanation:
Data integration aims at consolidating data from disparate sources into a single dataset provide users with consistent access to data that will meet their various needs. However, the process of data integration faces many challenges. One of the challenges is disparate data formats and sources. There is also the velocity or speed at which data are gathered. For successful data integration, the different datasets need to be cleaned and updated with quality data.
Switched Ethernet, similar to shared Ethernet, must incorporate CSMA/CD to handle data collisions. True False
Answers
Answer:
False
Explanation:
The Carrier-sense multiple access with collision detection (CSMA/CD) technology was used in pioneer Ethernet to allow for local area networking. Carrier-sensing aids transmission while the collision detection feature recognizes interfering transmissions from other stations and signals a jam. This means that transmission of the frame must temporarily stop until the interfering signal is abated.
The advent of Ethernet Switches resulted in a displacement of the CSMA/CD functionality.

Explanation:
The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.
The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).

Answers
Answer:

Explanation:
Given
The attached code segment
Required
The output
The first and second lines initialize num2 to 32 and num1 to 12, respectively.
Next, the remainder is calculated on line 3
[tex]rem = 32\%12[/tex]
[tex]rem = 8[/tex]
Then the while loop is repeated as long as rem > 0.
At first, we have:
[tex]num2 = 32[/tex]
[tex]num1 = 12[/tex]
[tex]rem = 8[/tex]
The first iteration gives:
[tex]num2 = 12[/tex]
[tex]num1 = 8[/tex]
[tex]rem = 12\%8 = 4[/tex]
Is 4 > 0? Yes; The loop is executed again.
This gives:
[tex]num2 = 8[/tex]
[tex]num1 = 4[/tex]
[tex]rem = 8\%4=0[/tex]
Is 0 > 0? No; The loop is executed
The last statement prints the last value of num1;
In the last loop, we have:
[tex]num1 = 4[/tex]
Hence, the output is 4
