Answer:
The Power Button
Explanation:
There should be a power button on the side of your computer. You might need to press it and hold it, but it varies on different computers. If you are using a new Mac, press and hold down the same button you use for Touch ID.
Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading.
Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern.
For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example:
Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext = "WKH FDW LV YLVLEOH DW PLGQLIJKW"
The keys to decrypt this message are the shift number and the direction. The shift value can be any integer from 0 - 25. The above example uses shift = 3 and the shift direction is right or direction = 'r'.
Complete the CipherTest class by adding a constructor to initialize a cipher item. The constructor should initialize the shift to 0, and the direction to 'r' for right shift. If the constructor is called with a shift value, and direction, the constructor should assign each instance attribute with the appropriate parameter value.
Complete the following TODO's: (1) create input for text, shift value, and direction (use lower( )) to keep l and r lower case (2) create a cipher item and use the constructor with the above input values (3) use control structures to call shifttoright() if direction is right and call shifttoleft if direction is left. Make sure you print out the return encrypted message inside the control structures.
We can create the encrypted text by using the ord ( ) function. This function will return an integer that represents the Unicode code point of the character. Character are represented by different values for upp/er and lower case so an 'a' returns the integer 97. By using the unicode value we can add and subtract our shift value represented by an integer.
The given program accepts as input a text string as our message to be encrypted, a shift value, and a direction of 'l' for left and 'r' for right. The program creates a cipher item using the input values. The program outputs the encrypted message based on the shift value and the direction provided.
Ex: If the input is text = "Cryptography is fun!", shift = 4, and direction = l.
The output is:
The output of the text if the shift= 4 and the direction = l would be: Y.N.U.L.P.K.C.N.W.L.D.U E.O B.Q.J
What is Cryptography?This refers to the art of writing and solving codes through the use of ciphertext.
Hence, we can see that the ciphertext we have is that there is a shift of 4 and it moves in the leftward direction thus, using the letters of the English alphabet, we would encode this and the output is: Y.N.U.L.P.K.C.N.W.L.D.U E.O B.Q.J

Explanation:
It was a slow trend initially though, as I/O ports and disk controllers
This is your code. >>> A = [21, 'dog', 'red'] >>> B = [35, 'cat', 'blue'] >>> C = [12, 'fish', 'green'] >>> e = [A,B,C] How do you refer to 'green'? e(2, 2) e(2, 2) e(2)(2) e(2)(2) e[2][2] e[2][2] e[2, 2] e[2, 2]
So the final list is
e=[A,B,C]Then
e=[[21,'dog','red'],[35,'Cat','blue'],[12,'fish','green']]green is inside a nested list of index 2
C is at index 2 alsoHence required reference is
e[2][2]The probability of event A occurring is 10/10. The probability of event B occurring is 0/10. What is the entropy of this system? Please show work.
The events A and B are the outcomes of the probabilities in the system
The entropy of the system is 0
How to determine the entropy?The probabilities are given as:
P(A) = 10/10
P(B) = 0/10
The entropy is calculated using:
[tex]H(x) = -\sum \limits^{n}_{i = 1} p_i * \log_2(p_i)[/tex]
So, we have
[tex]H(x) = -10/10 * \log_2(10/10) - 0/10 * \log_2(0/10)[/tex]
Evaluate the products
[tex]H(x) = -\log_2(10/10) - 0[/tex]
Evaluate the sum
[tex]H(x) = -\log_2(10/10)[/tex]
Evaluate the quotient
[tex]H(x) =- \log_2(1)[/tex]
Express 1 as 2^0
[tex]H(x) =- \log_2(2^0)[/tex]
Apply the power rule of logarithm
[tex]H(x) =- 0\log_2(2)[/tex]
Evaluate the product
H(x) =0
Hence, the entropy of the system is 0

In this lab, you add a loop and the statements that make up the loop body to a C++ program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed.
The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X
Variables have been declared for you, and the input and output statements have been written.
Instructions
Ensure the source code file named LeftOrRight.cpp is open in the code editor.
Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class.
Execute the program by clicking the Run button and using the data listed above and verify that the output is correct.
// LeftOrRight.cpp - This program calculates the total number of left-handed and right-handed
// students in a class.
// Input: L for left-handed; R for right handed; X to quit.
// Output: Prints the number of left-handed students and the number of right-handed students.
#include
#include
using namespace std;
int main()
{
string leftOrRight = ""; // L or R for one student.
int rightTotal = 0; // Number of right-handed students.
int leftTotal = 0; // Number of left-handed students.
// This is the work done in the housekeeping() function
cout << "Enter an L if you are left-handed, a R if you are right-handed or X to quit: ";
cin >> leftOrRight;
// This is the work done in the detailLoop() function
// Write your loop here.
// This is the work done in the endOfJob() function
// Output number of left or right-handed students.
cout << "Number of left-handed students: " << leftTotal << endl;
cout << "Number of right-handed students: " << rightTotal << endl;
return 0;
}
Answer:
#include <iostream>
#include <string>
// R, R, R, L, L, L, R, L, R, R, L, X ==> 6R 5L X
void getLeftOrRight(std::string &l_or_r, int &total_l, int &total_r) {
// notice how the above line matches: getLeftOrRight(leftOrRight, leftTotal, rightTotal);
// the values provided from the loop are given nicknames for this function getLeftOrRight()
if (l_or_r == "L") { // left-handed
total_l++;
} else if (l_or_r == "R") { // right-handed
total_r++;
} else { // quit
// option must be "X" (quit), so we do nothing!
}
return; // we return nothing, which is why the function is void
}
int main() {
std::string leftOrRight = ""; // L or R for one student.
int rightTotal = 0; // Number of right-handed students.
int leftTotal = 0; // Number of left-handed students.
while (leftOrRight != "X") { // whilst the user hasn't chosen "X" to quit
std::cout << "Pick an option:" << std::endl;
std::cout << "\t[L] left-handed\n\t[R] right-handed\n\t[X] quit\n\t--> ";
std::cin >> leftOrRight; // store the user's option in the variable
getLeftOrRight(leftOrRight, leftTotal, rightTotal); // call a function, and provide it the 3 arguments
}
std::cout << "Number of left-handed students: " << leftTotal << std::endl;
std::cout << "Number of right-handed students: " << rightTotal << std::endl;
return 0;
}
Explanation:
This is my take on the question! I had no idea what was meant by the housekeeping(), detailLoop(), endOfJob() functions provided in their source code.
What my code does should be pretty explanatory via the comments and variable names within it — but feel free to make a comment to ask for more info! I've attached a screenshot of my code because I think it's easier to read when it's syntax highlighted with colors.
In this code, the while loop continues to execute as long as the user enters something other than 'X'.
You need to write a loop that repeatedly takes input from the user and updates the leftTotal and rightTotal variables based on the input until the user enters 'X' to quit.
Here's the completed code:
#include <iostream>
using namespace std;
int main()
{
string leftOrRight = ""; // L or R for one student.
int rightTotal = 0; // Number of right-handed students.
int leftTotal = 0; // Number of left-handed students.
cout << "Enter an L if you are left-handed, a R if you are right-handed or X to quit: ";
cin >> leftOrRight;
// Write your loop here.
while (leftOrRight != "X") {
if (leftOrRight == "L") {
leftTotal++;
} else if (leftOrRight == "R") {
rightTotal++;
}
cout << "Enter an L if you are left-handed, a R if you are right-handed or X to quit: ";
cin >> leftOrRight;
}
cout << "Number of left-handed students: " << leftTotal << endl;
cout << "Number of right-handed students: " << rightTotal << endl;
return 0;
}
In this code, the while loop continues to execute as long as the user enters something other than 'X'.
Inside the loop, the input is checked for either 'L' or 'R', and the appropriate total variable is incremented accordingly.
The loop then prompts the user for input again until the user decides to quit by entering 'X'.
Finally, the code displays the total number of left-handed and right-handed students.
