Answer:
Question 1: The pseudocode is as follows:
int n = 70;
int intArray[n];
for(int i = 0; i< n; i++){
print("Input "+(i+1)+": ")
input intArray[i];
}
Question 2: Advantages of array
Indexing in arrays in easyIt can be used to store multiple values of the same typeIt can be used for 2 dimensional inputsExplanation:
Question 1
This declares and initializes the length of the array
int n = 70;
This declares the array
int intArray[n];
This iterates through the length of the array
for(int i = 0; i< n; i++){
This prompts the user for inputs
print("Input "+(i+1)+": ")
This gets input for each element of the array
input intArray[i];
}
Question 2
Indexing: Elements of the array can easily be accessed through the index of the element.
For instance, an element at index 2 of array intArray can be accessed using: intArray[2]
Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.
2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).
An illustration is:
intArray[2][2] = {[0,1],[3,5]}
The above array has 2 rows, 2 columns and 4 elements in total.

Write a C++ program that reads a number and determines whether the number is positive, negative or zero using Switch operator method
Answer:
#include <iostream>
using namespace std;
template <typename T> int sgn(T val) {
return (T(0) < val) - (val < T(0));
}
int main()
{
cout << "Enter a number: ";
int number;
cin >> number;
switch (sgn(number)) {
case -1: cout << "The number is negative";
break;
case 0: cout << "The number is zero";
break;
case 1: cout << "The number is positive";
break;
}
}
Explanation:
You need the special sgn() function because a switch() statement can only choose from a list of discrete values (cases).

Suppose that in a 00-11 knapsack problem, the order of the items when sorted by increasing weight is the same as their order when sorted by decreasing value. Give an efficient algorithm to find an optimal solution to this variant of the knapsack problem, and argue that your algorithm is correct.
Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.
Question 6 Which of the following statements about datasets used in Machine Learning is NOT true? 1 point Testing data is data the model has never seen before and is used to evaluate how good the model is Training subset is the data used to train the algorithm Validation data subset is used to validate results and fine-tune the algorithm's parameters Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is
Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters

You are designing an application at work that transmits data records to another building in the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds
Is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? Show all your work.
Solution :
It is given that an application is used to transmit a data record form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.
a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.
b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer. So for this the line of transmission can be either wired or wireless.
Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

find the summation of even number between (2,n)
Answer:
The program in python is as follows:
n = int(input("n: "))
sum = 0
for i in range(2,n+1):
if i%2 == 0:
sum+=i
print(sum)
Explanation:
This gets input n
n = int(input("n: "))
This initializes sum to 0
sum = 0
This iterates through n
for i in range(2,n+1):
This checks if current digit is even
if i%2 == 0:
If yes, take the sum of the digit
sum+=i
Print the calculated even sum

mention 3 components that can be found at the back and front of the system unit
Answer:
Back
Power port, USB port, Game port
Front
Power button, USB port, Audio outlet
Explanation:
There are several components that can be found on the system unit.
In most (if not all) computer system units, you will find more component at the back side than the front side.
Some of the components that can be found at the back are:
Ports for peripherals such as the keyboard, mouse, monitor, USB ports, power port, etc.
Some of the components that can be found at the back are:
The power button, cd rom, audio usb ports, several audio outlets, video port, parallel ports, etc.
Note that there are more components on the system units. The listed ones are just a fraction of the whole components
JavaAssignmentFirst, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "BackwardsStrings" (without the quotation marks) that:Prompts the user at the command line for one 3-character string.Then (after the user inputs that first 3-character string) prompts the user for another 3-character string.Then prints out the two input strings with a space between them.Finally prints on a separate line the two input strings 'in reverse' (see example below) with a space between them.So, for example, if the first string is 'usr' and the second string is 'bin', your program would output something like the following:The two strings you entered are: usr bin.The two strings in reverse are: nib rsu.Note that the reversed SECOND string comes FIRST when printing the strings in reverse.my result/*Name: Saima SultanaLab:PA - BackwardsStrings (Group 2)*/package backwardsstrings;import java.util.Scanner;public class BackwardsStrings { public static void main(String[] args) { //variables String first, second; // TODO code application logic here StringBuilder firstReversed= new StringBuilder(); StringBuilder secondReversed= new StringBuilder(); Scanner input = new Scanner(System.in); // read strings first=input.nextLine(); second=input.nextLine(); // print out the input strings System.out.println("The two string you entered are:"+ first+" "+second+"."); // reverse the strings for ( int i=first.length()-1;i>=0; i--) firstReversed.append(first.charAt(i)); for ( int i=second.length()-1;i>=0; i--) secondReversed.append(second.charAt(i));// print out the reverse string System.out.println("The two strings in reverse are:"+secondReversed+" "+ firstReversed+ ".");}}
Answer:
Your program would run without error if you declared the first and second string variables before using them:

Program to print two strings in forward and reversed order
The program you added is correct. The only thing that needs to be done is variable declarations (because variables that are not declared cannot be used).
So, you need to declared first and second as strings. This can be done as follows:
(1) Only declaration
String first, second;
(2) Declaration and inputs
String first=input.nextLine();
String second=input.nextLine();

Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.
Proactive:
Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}
(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:
The following Python program should print the sum of all the even numbers from 0 to 10 (inclusive), but it has two bugs:
x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1

Answer:
tempF = (tempC * 1.8) + 32;
Explanation:
Required
Correct the error in the program
The error is due to tempF not been initialized or being calculated
Correct the error by writing the formula for tempF before tempF was printed
tempF = (tempC * 1.8) + 32;
Writing the formula ensures that tempF is initialized with the expected equivalent value for tempC
