Using a WHILE loop write a program that asks the user to guess your favorite number. The program should end when the user guesses correctly, but otherwise provides hints for guessing higher or lower. Use the Try/Except/Else structure to ensure that the user enters numbers. Name this program guessNumber.py

Answer:

A) expert user

Explanation:

An expert user is an experienced user who has spent considerable time using specific application programs and, therefore, it is fair to assume that this user is likely to become comfortable and familiar with the terminal's operation.

A casual user is a less experienced computer user who will generally use a computer less frequently and thus is not likely to become comfortable and familiar with the terminal's operation.

System owners and system builders are not technically users.

Therefore, the answer is A) expert user

#section 1

while True:

   try:

       major=input('Enter Major: ')

       if re.search(r'^\d{1,4}$',major):

           minor=input('Enter minor: ')

       else:

           raise

       try:

           if re.search(r'^\d{1,4}$',minor):

               sub1=input('Enter sub1: ')

           else:

               raise

           try:

               if re.search(r'^\d{1,4}$',sub1):

                   sub2=input('Enter sub2: ')

               else:

                   raise

               try:

                   if re.search(r'^\d{1,4}$',sub2):

                       break

                   else:

                       raise

               except:

                   print('enter a correct sub 2')

           except:

               print('enter a correct sub1')        

       except:

           print('Enter a correct minor ')            

   except:

        print('enter a correct Major')

#section 2

sub1= f"{int(sub1):04d}"

sub2= f"{int(sub2):04d}"

major= f"{int(major):04d}"

minor= f"{int(minor):04d}"

if major == '0000' and minor == '0000' and sub1=='0000' and sub2=='0000':

   print('INVALID!!! Acount Number')

else:

   print('-----------------------')

   print('Your Account Number is')

   print(major, minor, sub1, sub2)

   print('-----------------------')

Explanation:

The programming language used is python 3

The Regular  Expression Module was imported to allow us perform special operations on string variables.

This is the pattern that was used to check if an input was valid or invalid re.search(r'^\d{1,4}$',string)

what this pattern does is that it ensures that:

we also made use of fstrings

sub1= f"{int(sub1):04d}"

the above line of code takes 'sub1' in this case, and converts it temporarily to an integer and ensures it has a length of 4 by adding 0's in front of it to convert it to a four digit number.

These are the major though areas, but i'll explain the sections too.

#section 1

In this section the WHILE loop is used in conjunction with the TRY and EXCEPT block and the IF statement to ensure that the correct input is given.

The while loop will keep looping until the correct input is inserted  before it breaks and each input is tested in the try and except block using the if statement and the regular expression pattern I explained, as a result, you cannot input a letter, a blank space, a punctuation or numbers with length greater than 4, it has to be numbers within the range of 1-4.

#section 2

The second section converts each entry to a four digit number and checks with an if statement if the entry is all zeros (0000 0000 0000 0000) and prints invalid.

Otherwise, it prints the account number.

check the attachment to see how the script runs.

Two Python functions are defined: sumN to compute the sum of the first n natural numbers, and sumN_Cubes to compute the sum of the cubes of the first n natural numbers. A user is then prompted to input a number 'n', and the program prints out the results of both functions.

Defining Sum Functions in Python

To start with, let's define the two functions as described. The first function sumN will calculate the sum of the first n natural numbers. The second function sumN Cubes will calculate the sum of the cubes of the first n natural numbers. Then we will use these functions in a program that prompts the user for an input and prints out the results.

Here are the Python definitions:

def sumN(n):
   return sum(range(1, n+1))
def sumN_Cubes(n):
   return sum(x**3 for x in range(1, n+1))
n = int(input('Enter a number n: '))
print(f'Sum of the first {n} natural numbers is: {sumN(n)}')
print(f'Sum of the cubes of the first {n} natural numbers is: {sumN_Cubes(n)}')

The program first defines the functions using the def keyword. Then it prompts the user to enter a number and stores it as n. Lastly, it calculates and prints the results using the defined functions.a

Answer:

#include <iostream>

using namespace std;

int main()

{

   float altitude;

   cout<<"Enter alttitude in meter";

cin >>altitude;

if(altitude<0 || altitude > 50000)

{

   cout<<"Invalid value entered";

   return 0;

}

else{

   if(altitude<= 10000)

   {cout <<"In troposphere "<<endl;}

   else if(altitude>10000 && altitude<=30000)

   {cout <<"In lower stratosphere"<<endl;}

   else if(altitude>30000 && altitude<=50000)

   {cout <<"In upper stratosphere"<<endl;}

}

   return 0;

}

Explanation:

Define a float type variable. Ask user to enter altitude in meters. Store value to altitude variable.

Now check if value entered is positive and less than 5000,if its not in the range of 0-50,000 display a termination message and exit else check if it's in less than 10000, in between 10000 and 30000 or in between 30000 and 50000.

10,000 is above sea level is troposphere.

10,000-30,000 is lower stratosphere.

30,000-50,000 is upper stratosphere.

Answer:

Up to 99.99958% safer

Explanation:

Assuming the attacker knows the password restrictions (upper and lower case letters and digits only)

Lets calculate the password combinations for each possible length:

Total characters possible: [a-z]+[A-Z]+[0-9] = 62

(A) Passwords of length = 8  ->  [tex]62^8=218,340,105,584,896[/tex]

(B) Passwords of length = 7  ->  [tex]62^7=3,521,614,606,208[/tex]

(C) Passwords of length = 6  ->  [tex]62^6=56,800,235,584[/tex]

(D) Passwords of length = 5  ->  [tex]62^5=916,132,832[/tex]

If length is not known, but between 5 and 8:

(E) Passwords of length = [5-8] ->  

[tex]\sum_{5 \to 8} 62^{n} = \frac{62^9-62^5}{62-1}=221,919,436,559,520[/tex]

Finally, to compare how much safer is to keep the password length hidden, we'll calculate the percentage of (A) to (D) passwords against (E)

The formulas are:  

[tex]1-\frac{(A)}{(E)} *100 = 1.61\% safer[/tex]

[tex]1-\frac{(B)}{(E)} *100 = 98.41\% safer[/tex]

[tex]1-\frac{(C)}{(E)} *100 = 99.97\% safer[/tex]

[tex]1-\frac{(D)}{(E)} *100 = 99.99958\% safer[/tex]

Answer:  Database Architect

Explanation:

Answer:

The program to this question can be given as:

Program:

import java.util.*; //import package

public class Main //define class main.

{

public static void main(String[] args) //define main method.

{

ArrayList<String> AL1 = new ArrayList<>(); //create ArrayList object AL1.

LinkedList<String> LL2 = new LinkedList<>(); //create LinkedList object LL2.

AL1.addAll(Arrays.asList("Bihar","Andhra Pradesh","Assam","Chhattisgarh","Arunachal Pradesh","Goa","west bangol","Gujarat","Jharkhand","Karal"));//add elements in ArrayList

LL2.addAll(Arrays.asList("Bihar","Andhra Pradesh","Assam","Chhattisgarh","Arunachal Pradesh","Goa","west bangol","Gujarat","Jharkhand","Karal"));//add elements in LinkedList

Collections.sort(AL1); //sort ArrayList

Collections.sort(LL2); //sort LinkedList

System.out.println("Sorting in ArrayList and LinkedList elements :");

System.out.println("ArrayList :\n" +AL1);

System.out.println("LinkedList :\n"+LL2);

Collections.shuffle(AL1); //shuffle ArrayList

Collections.shuffle(LL2); //shuffle LinkedList

System.out.println("shuffling in ArrayList and LinkedList elements :");

System.out.println("shuffle ArrayList:\n"+AL1);

System.out.println("shuffle LinkedList:\n"+LL2);

}

}

Output:

Sorting in ArrayList and LinkedList elements :

ArrayList :

[Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Chhattisgarh, Goa, Gujarat, Jharkhand, Karal, west bangol]

LinkedList :

[Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Chhattisgarh, Goa, Gujarat, Jharkhand, Karal, west bangol]

shuffling in ArrayList and LinkedList elements :

shuffle ArrayList:

[Chhattisgarh, Jharkhand, Gujarat, Goa, west bangol, Andhra Pradesh, Arunachal Pradesh, Assam, Karal, Bihar]

shuffle LinkedList:

[Assam, Karal, Jharkhand, Bihar, Goa, Arunachal Pradesh, Andhra Pradesh, Gujarat, west bangol, Chhattisgarh]

Explanation:

In the above java program firstly we import the package then we define the main method in this method we create the ArrayList and LinkedList object that is AL1 and LL2.

In ArrayList and LinkedList we add state names then we use the sort and shuffle function. and print all values.

Here's a C++ program that reads two rectangles' lengths and widths as integer values and tests if they are similar:

#include <iostream>

#include <cmath>

using namespace std;

bool areSimilar(int length1, int width1, int length2, int width2) {

   float lengthRatio = static_cast<float>(length1) / static_cast<float>(length2);

   float widthRatio = static_cast<float>(width1) / static_cast<float>(width2);

   return lengthRatio == widthRatio;

}

int main() {

   int length1, width1, length2, width2;

   cout << "Enter the length and width of the first rectangle: ";

   cin >> length1 >> width1;

   cout << "Enter the length and width of the second rectangle: ";

   cin >> length2 >> width2;

   if (areSimilar(length1, width1, length2, width2)) {

       cout << "The two rectangles are similar." << endl;

   } else {

       cout << "The two rectangles are not similar." << endl;

   }

   return 0;

}

This program defines a function areSimilar that takes the lengths and widths of two rectangles as input and returns a boolean value indicating whether the rectangles are similar. The function calculates the ratios of the lengths and widths and checks if they are equal. If the ratios are equal, the rectangles are considered similar, and the function returns true. Otherwise, the rectangles are not similar, and the function returns false.

   print(result)

str = "chair dairy boss circuis fly dog church clue dish"

nounToplural(str)

Explanation:

We made use or Regular Expressions which is simply a special sequence of characters that helps you match or find other strings or sets of strings, by using a specialized syntax held in a pattern.

Firstly, define the function and import the regular expression module, split the text into a list and create an empty list to hold the plural list.

For every word in the list  we check with IF statements and regular expressions to find out what they end with.

 if re.findall(r"y\b", word):

           word = re.sub(r"y\b", 'ies' ,word)

           new.append(word)

The above IF block checks if a noun ends with 'y', if it does it replaces the 'y' with 'ies' and ads it to the new list.

If it does not, ot moves to the next IF/ELIF block.

In the ELIF blocks carry out a  a similar operation for "s", "ch", or "sh", in order to add "es".

Finally, 's' is added to all other cases using the ELSE block which traps any noun that did not fall under the IF or any of the ELIF blocks.

This last part of the code prints both list side by side and passes them to a new list result which is printed to the screen

result = []

   for i in text:

       for j in new:

           if new.index(j) == text.index(i):

               result.append( (i,j) )

   print(result)

I called the function and passed the string you provided in your question and attached the result of the code.

Wide area network (WAN)

Explanation:

The WAN network is a type of network that covers distances of about 100 to about 1,000 kilometers, allowing to provide connectivity to several cities or even an entire country. WAN networks can be developed by a company or an organization for private use, or even by an Internet Service Provider (ISP) to provide connectivity to all its customers. Generally, the WAN network operates point to point, so it can be defined as a switched packet network. These networks, on the other hand, can use radio or satellite communication systems.

Answer:

The code to this question can be given as:

Code:

//define code.

//conditional statements.

   if (Character.isLetter(passCode.charAt(0))) //if block

   {

       System.out.println("Alphabetic at 0"); //print message.

   }

   if (Character.isLetter(passCode.charAt(1))) //if block

   {

       System.out.println("Alphabetic at 1"); //print message.

   }

Explanation:

In this code, we define conditional statement and we use two if blocks. In both if blocks we use isLetter() function and charAt() function. The isLetter() function checks the inserted value is letter or not inside this function we use charAt() function that checks inserted value index 1 and 2 is the character or not.

The code segment is an illustration of conditional statements

Conditional statements are statements whose execution depends on the truth value of the condition.

The code segment in Java, where comments are used to explain each line is as follows:

//This checks if the first character is an alphabet.

if (Character.isLetter(passCode.charAt(0))){

   //If yes, this prints alphabetic at 0

   System.out.println("Alphabetic at 0");

}

//This checks if the second character is an alphabet.

if (Character.isLetter(passCode.charAt(1))){

   //If yes, this prints alphabetic at 1

   System.out.println("Alphabetic at 1");

}

Answer:

The correct option is Option C: It matches a new problem with a previously solved problem and its solution.

Explanation:

Case-based reasoning (CBR) is used when someone tries to solve new problems based on old problems that were similar. The person applying case-based reasoning would look for the solutions to these similar past problems and try to apply them to the new case. For example, a doctor who tries to treat a patient based on what was successful with a prior patient with a similar problem is applying case-based reasoning. In some instances, these problems are available in a database and ideally, that is how it is conceived, but it would depend on the field and the kind of problems. There is no universal global network dedicated to CBR as a whole (other than generic searches on the internet in general). One example of a specific CBR database is the European Nuclear Preparedness system called PREPARE.

Final answer:

The safeOpen() function in Python is used to open a file while handling exceptions. It returns the file object on success, or None if an error occurs, thus ensuring that the program can continue to run without crashing.

Explanation:

The function safeOpen() is designed to handle file operations within a Python program safely by attempting to open a file and returning a file object if successful, or None if an exception occurs. This function makes use of Python's built-in exception handling mechanisms to provide a secure way of accessing files. Here's an example of how you can define the safeOpen() function:
def safeOpen(filename):
   try:
       file = open(filename, 'r')
       return file
   except Exception as e:
       print("An error occurred: ", e)
       return None
In this code snippet, the try block attempts to open the specified file in read mode. If the file is opened successfully, the file object is returned. If any exception, such as FileNotFoundError or PermissionError, is raised during the attempt, the except block is executed, printing out the error message and returning None.

Final answer:

To find all .conf files in the /etc directory, use the find command and redirect the output to a file. Knowledge of navigating directories and handling file permissions is also applicable.

Explanation:

The student has asked for assistance in searching for configuration files in the directory /etc, including all of its subdirectories, that end with the .conf extension. To accomplish this task, one can use the find command in a Unix-based system. Here's an example of how this command can be structured:

find /etc -type f -name "*.conf" > s9

This command will search for all files (-type f) within the /etc directory and its subdirectories that match the name pattern (-name "*.conf") and redirect the output to a file named s9. The student is also advised on how to navigate directories using both absolute and relative paths and how to handle any 'Permission Denied' errors that may occur during the execution of the find command.

Furthermore, it is important to note that file permissions, as per Unix file system conventions, may prevent certain directories from being accessible to non-root users.

int[] a = new int[]{18,16, 15, 6, 2};

int[] b = new int[]{13, 12, 11, 7, 1};

int[] ar;

//call function

ar = sort_Array(a, b);

//print message

System.out.println("\nThe resultant array is: \n");

//set for loop to print array

for(int x=0; x<ar.length; x++)

{

System.out.print(ar[x] + " ");

}

}

}

Output:

Number of compares done: 5

The resultant array is:

18 16 15 13 12 11 7 6 2 1

Explanation:

Here, we define a class "Main" inside the class, define a function "sort_Array()"and pass two integer type array argument "a" and "b".

Finally, define the main method inside it, we set two integer type array variable and initialize elements in them then, set the for loop to print the sorted elements of the array.

Answer:

easy. i've done this with my family before. take a bike or skateboard to the park with your family. maybe invite some friends over, or just spend the day at their house. this is obviously a good time to finish any home-work if you have any left. you can make a few extra bucks by doing some extra chores done (just make sure to tell your parents about it first;)). i hate not having technology, but i mean it's not the end of the world.

Explanation:

Nowadays, we rely on technology heavily. Because of this, it can be difficult to imagine what we would do without it. However, avoiding technology for a few days can be an enriching experience.

There are many things that you can do with your family without the use of technology. For example, if you are at a different location and there is nature around, you can go camping. You can make a fire to cook, swim, look at the stars and hike. If you are in the city, you can go to a park and read, or play a sport. You can also take advantage of this experience to talk more to your family and get to know them better.

Answer:

Assembly line.

Explanation:

The interchangeable parts was a game-changing concept for the manufacturing industry during the Industrial Revolution.

It was first introduced by Eli Whitney, also the inventor of the Cotton Gin, and later was perfected by Henry Ford, who was the first to create a continuous moving assembly line. The Interchangeable parts are identical pieces created from a master model and are so similar to each other, that they can fit into any line of production of the same kind.

Thanks to these advances, the manufacturing process across all industries could be now faster, more cost-efficient, and profitable.
