Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional.
Answer:
following are the program to the given question:
Program:
x = 0#defining an integer variable that holds a value
if x < 0:#defining if that checks x less than 0
print("This number ", x, " is negative.")#print value with the message
else:#defining else block
if x > 0:#defining if that checks x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
if x < 0:#defining another if that checks x less than 0
print("This number ", x, " is negative.")
elif (x > 0):#defining elif block that check x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
Output:
Please find the attachment file.
Explanation:
In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.
In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.
In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.

Answer: Why are there so many of these?
The modern computer system has been evolutionary. Modern computers have allowed for us to complete hard tasks rather easily. With modern computers, we are able to calculate advanced equations with the click of a button. Trends in computing like RTX can rapidly improve performance, rendering, and tons of other graphical heavy actions. In September of 2018, we got the first RTX card, now in 2021, RTX has become exponentially better than what it was in 2018. With the modern computers comes quantum computers. Quantum computing is estimated to be 100 million times faster than any modern computer. IBM, the company to make the first computer stated that we are in the decade of quantum computing. And who knows? Maybe quantum computing will come sooner rather than later.

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)

{
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.

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); }
}
Hope this helps.
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 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.

Answer:
B) the arithmetic mean of a list of values
Explanation:
on Edge
The Average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.
What is the average?In its most general definition, an average can be considered as the representative number or figure from the whole list. The average of a list containing multiple values is obtained by adding all the values and dividing them up by the total number of values.
The ultimate objective of calculating the average is to discover the value that represents the whole list. Average is also known as mean, and it works as a central value in the list, which is comprehensive in nature. It works as an approximate or rough estimate, which helps us in making decisions in daily life.
Thus, the average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.

Answer:
a. it designs its own applications but doesn't customize the operating system.
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Infrastructure as a Service (IaaS).
2. Software as a Service (SaaS).
3. Platform as a Service (PaaS).
Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Some of the advantages of Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
Basically, platform as a Service (PaaS) providers (vendors) usually provide their clients (software developers) with server and data storage, operating system, data center, networking resources, etc., while the software developers design, deploy and manage their software applications.
Hence, a business should choose the platform as a service (PaaS) cloud model when it designs its own applications but doesn't customize the operating system.
Prepare an algorithm and draw a corresponding flowchart to compute the
mean value of all odd numbers between 1 and 100 inclusive.
Answer:
Algorithm :
1.START
2. sum=0 ; n=1 ; length = 1
3. sum = sum + n
4. n = n + 2
5. length = length + 1
6. Repeat steps 3, 4 and 5 until n <= 99
7. mean = sum / length
8. print(mean)
Explanation:
Sum initializes the addition of the odd numbers
n starts from 1 and increments by 2, this means every n value is a odd number
The condition n <= 99 ensures the loop isn't above range isn't above 100 ;
The length variable, counts the number of odd values
Mean is obtained by dividing the SUM by the number of odd values.

What type of address do computers use to find something on a network?
You have a contactless magnetic stripe and chip reader by Square. What type of wireless transmission does the device use to receive encrypted data
Answer:
Near field communication (NFC)
Explanation:
Near field communication (NFC) can be defined as a short-range high radio-frequency identification (RFID) wireless communication technology that is used for the exchange of data in a simple and secure form, especially for electronic devices within a distance of about 10 centimeters.
Also, Near field communication (NFC) can be used independently or in conjunction with other wireless communication technology such as Bluetooth.
Some of the areas in which Near field communication (NFC) is used are confirmation of tickets at a concert, payment of fares for public transport systems, check-in and check-out in hotels, viewing a map, etc.
Assuming you have a contactless magnetic stripe and chip reader by Square. Thus, the type of wireless transmission that this device use to receive encrypted data is near field communication (NFC).

design a relational database in EER for bike helmets and their reviews. a bike helmet has a name and color attributes. a bike company has its name (primary key) and location attributes
Answer:something you gotta do on your own
Explanation:
EER diagrams are essentially an expanded form of entity-relationship (ER) diagrams. EER models are useful tools for creating high-level model databases. By carefully examining the qualities and limitations, you may plan databases more thoroughly thanks to their improved features.
What design a relational database in EER?Set up a relationship table. Include the main keys of all involved Entities in the table as fields with the appropriate data types. Add each attribute as a table field if the relationship has any. Establish a primary key by combining the primary keys of all involved entities.
The modeling interface in MySQL Workbench is absolutely dependent on Enhanced Entity-Relationship (EER) diagrams. The relationships between the tables in your model are depicted visually in EER diagrams.
Therefore, The related diagram displays modifications performed using the Model Editor.
