If i took my SIM card out of my phone and put it in a router then connect the router and my phone with Ethernet cable would the ping change?
Answer:
The ping will change.
Explanation:
Assuming you mean ping from device with SIM card to another host (no mater what host), the ping will change. Ping changes even on the same device because network speed and performance of all the nodes on the route changes continuously. However, if two of your devices (phone & router) are configured differently (use different routing under the hood), then it will also affect the ping.
I'm using Visual Studio to make a grocery app for school that includes usernames and passwords. I'm given all the code then it tells me to use search arrays to implement two functions. They should return true if the username and password is found in the arrays. But i can't seem to get the function and arrays right. Below is the code and I'm supposed to implement the array in the two empty functions at the bottom. Would really appreciate some help here, thanks
Module Main
Friend blnLoggedIn As Boolean
Dim arrUsernames() As String = {"Admin", "Clerk", "Manager"}
Dim arrPasswords() As String = {"password", "password2", "password3"}
Sub Login(username As String, password As String)
blnLoggedIn = False
If VerifyUsername(username) And VerifyPassword(password) Then
'Find index for username
Dim userIndex As Integer
For loopIndex = 0 To arrUsernames.Length - 1
If arrUsernames(loopIndex) = username Then
userIndex = loopIndex
Exit For
End If
Next
'Check for password match
If arrPasswords(userIndex) = password Then
blnLoggedIn = True
Else
MessageBox.Show("Incorrect password.")
End If
End If
End Sub
Function VerifyUsername(username As String) As Boolean
End Function
Function VerifyPassword(password As String) As Boolean
End Function
End Module
Answer:
VB:
Public Function VerifyUsername(ByVal username As String) As Boolean
For positionInUsernameArray As Integer = 0 To arrUsername.Length - 1
If positionInUsernameArray = arrUsername.Length Then Exit For
If username = arrUsername(positionInUsernameArray) Then
Return True
Else
Continue For
End If
Next
Return False
End Function
Public Function VerifyPassword(ByVal password As String) As Boolean
For positionInUsernameArray As Integer = 0 To arrPassword.Length - 1
If positionInUsernameArray = arrPassword.Length Then Exit For
If password = arrPassword(positionInUsernameArray) Then
Return True
Else
Continue For
End If
Next
Return False
End Function
C#:
sealed class Main
{
internal bool blnLoggedIn;
string[] arrUsername = new string[] { "Admin", "Clerk", "Manager" };
string[] arrPassword = new string[] { "password", "password2", "password3" };
public void Login(string username, string passowrd)
{
blnLoggedIn = false;
if (VerifyUsername(username) && VerifyPassword(passowrd))
{
// Find index for username
int userIndex = 0;
for (int loopIndex = 0; loopIndex <= arrUsername.Length - 1; loopIndex++)
{
if (arrUsername[loopIndex] == username)
{
userIndex = Convert.ToInt32(loopIndex);
break;
}
else continue;
}
// Check for password match
if (arrPassword[userIndex] == passowrd)
blnLoggedIn = true;
else
MessageBox.Show("Incorrect password");
}
}
public bool VerifyUsername(string username)
{
for (int positionInUsernameArray = 0; positionInUsernameArray <= arrUsername.Length - 1; positionInUsernameArray++)
{
if (positionInUsernameArray == arrUsername.Length)
break;
if (username == arrUsername[positionInUsernameArray])
return true;
else continue;
}
return false;
}
public bool VerifyPassword(string password)
{
for (int positionInUsernameArray = 0; positionInUsernameArray <= arrPassword.Length - 1; positionInUsernameArray++)
{
if (positionInUsernameArray == arrPassword.Length)
break;
if (password == arrPassword[positionInUsernameArray])
return true;
else continue;
}
return false;
}
}
Explanation:
First I created a for loop with a "positionInUsernameArray" and singed it a value of 0. Next I stated while positionInUsernameArraywas less than or equal to arrUsername.Length - 1, positionInUsernameArraywould increment.
Once the base for loop was in place I created two if statements. The first if statement determines if positionInUsernameArray is equal to arrUsername.Length, if so, the for loop breaks and the method returns false. The second if statement determines if the parameter is equal to the position in the arrUsername array, if so, the method would return true, otherwise the for loop will restart.
For the "VerifyPassword" method, I used the same method as "VerifyUsername" just I changed the variable names.
Hope this helped :) If it didn't please let me know what happened so I can fix the code.
Have a good day!

Write a Java program to create a class called Cars. The class should include three instance variables: makes (type: String), models (type: String), and years (type: int); and two methods: a constructor() to initialize three variables and a show() to display the information of a car. Write a class called TestCars to test the class Cars. This class should be able to read the makes, models, and years of three cars from screen input, create three-car objects using the constructor() and display each car's make, model, and years using the show(). (5pts)
Answer:
Explanation:
This code was written in Java. It creates the Cars class with the requested variables and methods. It also creates the TestCars class which asks the user for the necessary inputs and then creates three Cars objects and passes the input values to the constructors. Finally, it uses the show() method on each object to call the information. A test has been created and the output can be seen in the attached image below.
import java.util.Scanner;
class TestCars{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter Car Make: ");
String make1 = in.next();
System.out.print("Enter Car Model: ");
String model1 = in.next();
System.out.print("Enter Car Year: ");
int year1 = in.nextInt();
System.out.print("Enter Car Make: ");
String make2 = in.next();
System.out.print("Enter Car Model: ");
String model2 = in.next();
System.out.print("Enter Car Year: ");
int year2 = in.nextInt();
System.out.print("Enter Car Make: ");
String make3 = in.next();
System.out.print("Enter Car Model: ");
String model3 = in.next();
System.out.print("Enter Car Year: ");
int year3 = in.nextInt();
Cars car1 = new Cars(make1, model1, year1);
Cars car2 = new Cars(make2, model2, year2);
Cars car3 = new Cars(make3, model3, year3);
car1.show();
car2.show();
car3.show();
}

class Cars {
String makes, models;
int years;
public Cars(String makes, String models, int years) {
this.makes = makes;
this.models = models;
this.years = years;
}
public void show() {

When you are making multiples of a brownie recipe, you cannot - without great difficulty - use a fraction of an egg. The calculate_eggs function uses the ceil function in the math module to always round up and provide the total number of eggs you need on hand to make your recipe.
1. On Line 2, import just the ceil function from the math module
2. On Line 6, call the ceil function to calculate 0.6*servings
When you run the code, it should match the output under Desired Output
# Import ceil function only from the math module
import math.ceil
# Define Function
def calculate_eggs(servings):
total_eggs = (0.6*servings)
return total_eggs
# Call Function
print(calculate_eggs(14))
Desired Output = You need 9 eggs
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Answer:
Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a space, including the last one.

The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is: 7
the out put is :fibonacci(7) is 13
import java.util.Scanner;
public class LabProgram {
public static int fibonacci(int n) {
/* Type your code here. */
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int startNum;
System.out.println("Enter your number: ");
startNum = scnr.nextInt();
System.out.println("fibonnaci(" + startNum + ") is " + fibonacci(startNum));
}
}
You could use recursion to write java method for computing fibonacci numbers. Though it will be inefficient for n > about 50, it will work.
public static int fibonacci(int n) {
if (n < 0) { return -1; }
if (n < 2) { return n; }
else { return fibonacci(n-1)+fibonacci(n-2); }
}

The current term of a Fibonacci series is derived by adding the two previous terms of its sequence; and the first two terms are 0 and 1.
The code segment (without comments) that completes the program is as follows:
int T1 = 0, T2 = 1, cT;
if (n < 0){
return -1; }
for (int i = 2; i <= n; i++) {
cT = T1 + T2;
T1 = T2;
T2 = cT; }
return T2;
With comments (to explain each line)
/*This declares the first term (T1), the second term (T2) and the current term (CT).
T1 and T2 are also initialized to 0 and 1, respectively
*/
int T1 = 0, T2 = 1, cT;
//This returns -1, if n is negative
if (n < 0){ return -1;
}
//The following iterates through n
for (int i = 2; i <= n; i++) {
//This calculates cT
cT = T1 + T2;
//This passes T2 to T1
T1 = T2;
//This passes cT to T2
T2 = cT;
}
//This returns the required term of the Fibonacci series
return T2;
At the end of the program, the nth term of the series would be returned to the main method for output.

Write a program that asks the user to enter 5 test scores. The program will display a letter grade for each test score and an average grade for the test scores entered. Three functions are needed for this program.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double average(double s1, double s2, double s3, double s4, double s5){
double avg = (s1 + s2 + s3 + s4 + s5)/5;
return avg;}
char lGrade(double score){
char grade;
if(score>= 90 && score <= 100){ grade ='A'; }
else if(score>= 80 && score <= 89){ grade ='B'; }
else if(score>= 70 && score <= 79){ grade ='C'; }
else if(score>= 60 && score <= 69){ grade ='D'; }
else if(score < 60){ grade ='F'; }
return grade;}
int main(){
double s1,s2,s3,s4,s5;
cin>>s1>>s2>>s3>>s4>>s5;
double avg = average(s1,s2,s3,s4,s5);
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
cout<<avg<<" "<<lGrade(avg)<<endl;
return 0;}
Explanation:
The three functions to include in the program are not stated; so, I used the following functions in the program
1. The main function
2. average function
3. Letter grade function
The average function begins here
double average(double s1, double s2, double s3, double s4, double s5){
This calculates the average
double avg = (s1 + s2 + s3 + s4 + s5)/5;
This returns the calculated average
return avg;}
The letter grade function begins here
char lGrade(double score){
This declares the grade
char grade;
If score is between 90 and 100 (inclusive), grade is A
if(score>= 90 && score <= 100){ grade ='A'; }
If score is between 00 and 89 (inclusive), grade is B
else if(score>= 80 && score <= 89){ grade ='B'; }
If score is between 70 and 79 (inclusive), grade is C
else if(score>= 70 && score <= 79){ grade ='C'; }
If score is between 60 and 69 (inclusive), grade is D
else if(score>= 60 && score <= 69){ grade ='D'; }
If score is less than 60, grade is F
else if(score < 60){ grade ='F'; }
This returns the calculated grade
return grade;}
The main begins here
int main(){
This declares the 5 scores
double s1,s2,s3,s4,s5;
This gets input for the 5 scores
cin>>s1>>s2>>s3>>s4>>s5;
This calls the average function for average
double avg = average(s1,s2,s3,s4,s5);
This calls the letter grade function for the 5 scores
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
This calls the average function for the average
cout<<avg<<" "<<lGrade(avg)<<endl;

Answer:
2575
Explanation:
you just multiply.
1) Declare an ArrayList named numberList that stores objects of Integer type. Write a loop to assign first 11 elements values: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024. Do not use Math.pow method. Assign first element value 1. Determine each next element from the previous one in the number List. Print number List by using for-each loop.
Answer:
Explanation:
The following is written in Java and uses a for loop to add 10 elements to the ArrayList since the first element is manually added as 1. Then it calculates each element by multiplying the previous element (saved in count) by 2. The program works perfectly and without bugs. A test output can be seen in the attached image below.
import java.util.ArrayList;

public static void main(String[] args) {
ArrayList<Integer> numberList = new ArrayList<>();
numberList.add(0, 1);
int count = 1;
for (int i = 1; i < 11; i++) {
numberList.add(i, (count * 2));
count = count * 2;
}
for (Integer i : numberList) {
System.out.println(i);

Lab Experiment
Field Experiment
Natural Experiment.
Answer:
Experimental research for individuals in the physical sciences and many other fields is the best-known kind of research design. The main reason is that experimental research is a typical scientific experiment, similar to that carried out in secondary schools.
Explanation:
The types of research designs are determined by how the researchers assign subjects to various conditions and groups. They are of three different types: pre-experimental, almost experimental, and real experimental research.
Pre-experimental Research Design:-
In pre-experimental research, the effect of the application of a supposedly changing independent variable is observed by either a group or different dependent groups. It is the simplest form of experimental design and does not involve a control group.
Quasi-experimental Research Design:-
The term "almost" refers to partial, half, or pseudo. The quasi-experimental research therefore resembles, but not the same, the real experimental research. The participants are not assigned randomly in quasi-examples and are therefore used in environments that are difficult or unable to randomize.
True Experimental Research Design:-
To confirm or refute a hypothesis, real experimental research is based on statistical analyses. It is the most exact experimental type and can be performed on two randomly assigned subjects with, or without a pretest.
The true experimental design of the research must include a control group, a variable that the researcher can manipulate and the distribution must be random.

Write a program that defines an array of integers and a pointer to an integer. Make the pointer point to the beginning of the array. Then, fill the array with values using the pointer (Note: Do NOT use the array name.). Enhance the program by prompting the user for the values, again using the pointer, not the array name. Use pointer subscript notation to reference the values in the array.

The total sales for all the weeks. (Should print 1 value)
The average weekly sales. (Should print 1 value)
The week with the highest amount in sales. (Should print 1 week #)
The week with the lowest amount in sales. (Should print 1 week #)
The file contains the dollars amount of sales that a retail store made each day for a number of weeks. Each line in the file contains thirty five numbers, which are sales numbers for five weeks. The number are separated by space. Each line in the file represents a separate store.

I'm going to try and help you with this question.
Explanation:
Just give me a few minutes.
Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150
Answer:
Explanation:
The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.
function primes(n) {
//Boolean Array to check which numbers from 1 to n are prime
const boolArr = new Array(n + 1);
boolArr.fill(true);
boolArr[0] = boolArr[1] = false;
for (let i = 2; i <= Math.sqrt(n); i++) {
for (let j = 2; i * j <= n; j++) {
boolArr[i * j] = false;
}
}
//New Array for Only the Prime Numbers
const primeNums = new Array();
for (let x = 0; x <= boolArr.length; x++) {
if (boolArr[x] === true) {
primeNums.push(x);
}
}
return primeNums;
}
alert(primes(150));
Question: Name the person who originally introduced the idea of patterns as a solution design concept.
Answer:
architect Christopher Alexander is the person who originally introduced the idea of patterns as a solution design concept.
The person who originally introduced the idea of patterns as a solution design concept named as Christopher Alexander who was an architect.
What is architecture?Architecture is referred to as an innovative technique or artwork based on buildings or physical structures that aims at creating cultural values for upcoming generations to understand the importance of history.
The external layout can be made to best support human existence and health by using a collection of hereditary solutions known as the "pattern language." It creates a set of helpful relationships by combining geometry and social behavior patterns.
Christopher Alexander, a British-American engineer and design theorist of Austrian heritage, is renowned for his several works on the design and construction process introduced the idea of patterns as a solution design concept.

State the Data types with two examples each
Answer:
A string, for example, is a data type that is used to classify text and an integer is a data type used to classify whole numbers. When a programming language allows a variable of one data type to be used as if it were a value of another data type, the language is said to be weakly typed. Hope it help's! :D
