Write a program that produces a Caesar cipher of a given message string. A Caesar cipher is formed by rotating each letter of a message by a given amount. For example, if your rotate by 3, every A becomes D; every B becomes E; and so on. Toward the end of the alphabet, you wrap around: X becomes A; Y becomes B; and Z becomes C. Your program should prompt for a message and an amount by which to rotate each letter and should output the encoded message.
Answer:
Here is the JAVA program that produces Caeser cipher o given message string:
import java.util.Scanner; //to accept input from user
public class Main {
public static void main(String args[]) { //start of main function
Scanner input = new Scanner(System.in); //creates object of Scanner
System.out.println("Enter the message : "); //prompts user to enter a plaintext (message)
String message = input.nextLine(); //reads the input message
System.out.println("Enter the amount by which by which to rotate each letter : "); //prompts user to enter value of shift to rotate each character according to shift
int rotate = input.nextInt(); // reads the amount to rotate from user
String encoded_m = ""; // to store the cipher text
char letter; // to store the character
for(int i=0; i < message.length();i++) { // iterates through the message string until the length of the message string is reached
letter = message.charAt(i); // method charAt() returns the character at index i in a message and stores it to letter variable
if(letter >= 'a' && letter <= 'z') { //if letter is between small a and z
letter = (char) (letter + rotate); //shift/rotate the letter
if(letter > 'z') { //if letter is greater than lower case z
letter = (char) (letter+'a'-'z'-1); } // re-rotate to starting position
encoded_m = encoded_m + letter;} //compute the cipher text by adding the letter to the the encoded message
else if(letter >= 'A' && letter <= 'Z') { //if letter is between capital A and Z
letter = (char) (letter + rotate); //shift letter
if(letter > 'Z') { //if letter is greater than upper case Z
letter = (char) (letter+'A'-'Z'-1);} // re-rotate to starting position
encoded_m = encoded_m + letter;} //computes encoded message
else {
encoded_m = encoded_m + letter; } } //computes encoded message
System.out.println("Encoded message : " + encoded_m.toUpperCase()); }} //displays the cipher text (encoded message) in upper case letters
Explanation:
The program prompts the user to enter a message. This is a plaintext. Next the program prompts the user to enter an amount by which to rotate each letter. This is basically the value of shift. Next the program has a for loop that iterates through each character of the message string. At each iteration it uses charAt() which returns the character of message string at i-th index. This character is checked by if condition which checks if the character/letter is an upper or lowercase letter. Next the statement letter = (char) (letter + rotate); is used to shift the letter up to the value of rotate and store it in letter variable. This letter is then added to the variable encoded_m. At each iteration the same procedure is repeated. After the loop breaks, the statement System.out.println("Encoded message : " + encoded_m.toUpperCase()); displays the entire cipher text stored in encoded_m in uppercase letters on the output screen.
The logic of the program is explained here with an example in the attached document.
In this exercise we have to use the computer language knowledge in JAVA to write the code as:
the code is in the attached image.
In a more easy way we have that the code will be:
import java.util.Scanner;
public class Main {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.println("Enter the message : ");
String message = input.nextLine();
System.out.println("Enter the amount by which by which to rotate each letter : ");
int rotate = input.nextInt();
String encoded_m = "";
char letter;
for(int i=0; i < message.length();i++) {
letter = message.charAt(i);
if(letter >= 'a' && letter <= 'z') {
letter = (char) (letter + rotate);
if(letter > 'z') {
letter = (char) (letter+'a'-'z'-1); }
encoded_m = encoded_m + letter;}
else if(letter >= 'A' && letter <= 'Z') {
letter = (char) (letter + rotate);
if(letter > 'Z') {
letter = (char) (letter+'A'-'Z'-1);}
encoded_m = encoded_m + letter;}
else {
encoded_m = encoded_m + letter; } }
System.out.println("Encoded message : " + encoded_m.toUpperCase()); }}

Now that we understand Copyright, what would need to change in order for the scenario from the warm-up to be okay?
Answer:
I will develop a CREATIVE COMMONS LICENSE
Explanation:
Based on the scenario given what i would need to change for the scenario from the warm-up to be okay is for me develop CREATIVE COMMONS LICENSE and the reason why I would develop this type of license is that it will enable people or the public to freely make use of my work or have free licence to the work that I have created by freely using it on their own products which will enables them to sell their work which have my own work on them easily and freely without any form of restrictions.
Copyright allows the creator or owner of a property (usually intellectual property) to have an absolute right over his property.
What needs to be done in this scenario is to create a creative common license.
In copyright, creative common license allows the members of the public to make use of an intellectual property for free, while the owner still retains the ownership and right, over the property.
When the creative common license is done, the seller of the T-shirt can sell the T-shirt without remitting any incentive to you; however, the seller gives you credit and recognition for the image.

A DBMS commonly receives data update requests from application programs.A. TrueB. False
Answer:
A. True
Explanation:
DBMS is an acronym for database management system and it can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Some examples of a database management system (DBMS) are RDBMS, Oracle, SQL server, PostgreSQL, dBASE, Clipper, MySQL, Microsoft Access, etc.
A DBMS commonly receives data update requests from application programs through the Open Database Connectivity ( ODBC ) driver in case of communication with other database management softwares.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Write a program that simulates a lottery. The program should havean array of five integers named lottery, and shouldgenerate a random number in the range of 0 through 9 for eachelement in the array. The user should enter five digits whichshould be stored in an integer array named user. Theprogram is to compare the corresponding elements in the two arraysand keep a count of the digits that match. For example, thefollowing shows the lottery array and the user array with samplenumbers stored in each. There are two matching digits (elements 2and 4).
lottery array: 7,4,9,1,3
user array: 4,2,9,7,3
The program should display the random numbers stored in the lotteryarray and the number of matching digits. If all the digits match,display a message proclaiming the user as a grand prize winner.
Answer:
Here is the C++ program that simulates lottery:
#include<iostream> //to use input output functions
using namespace std; //to access objects cin cout
int main(){ //start of main function
int size= 5; // size of arrays
int range = 10; //range of random numbers from 0 to 9
int user[size]; // user array
int lottery[size]; // lottery array
for(int i=0;i<size;i++) //iterates through the array
lottery[i]=rand()%range; // generates random number in specified range
cout<<"Enter "<<size<<" digits: "; //prompts user to enter 5 digits
for(int i=0;i<size;i++) //loops through the user array
cin>>user[i]; //reads input digits from user
int match=0; //stores number of matching digits
for(int i=0;i<size;i++) //iterates through array to compare user and lottery arrays
if(user[i]==lottery[i]) //if digit at i-th index of user array matches to that of lottery array
match++; //increments count of matching digits by 1
cout<<"Lottery array: "; // display digits of lottery array
for(int i=0;i<size;i++) //iterates through elements of lottery array
cout<<lottery[i]<<" "; //prints elements of lottery array with a space between them
cout<<endl; //prints a new line
cout<<" User array: "; // prints digits of user array
for(int i=0;i<size;i++) //iterates through elements of user array
cout<<user[i]<<" "; //prints elements of user array
cout<<endl; // prints a new line
if(match==size){ //if all the digits match
cout<<"Congratulations. You are a grand prize winner! "; }//displays this message proclaiming the user as a grand prize winner
else{ // if all digits of user array do not match with lottery array digits
cout<<"Number of digits matched: "<<match<<endl; //displays the number of matched digits
cout<<"Sorry! Better luck next time!" ; //displays this message when all digits don't match
}
}
Explanation:
If you want to keep the size and range fixed then you can use #define before the main() function to give a constant value to size and range as:
#define size 5
#define range 10
The program uses rand() function in order to generate random numbers for lottery array in the range of 0 through 9.
Then the program declares a user array with size = 5 and prompts user to enter 5 digits to stores in user array.
Next the program matches each digit of user array to the corresponding digit of lottery array and if the two digits match then the program increments the match variable by 1 to count the matched digits. For example, lets say lottery has the following elements:
lottery: 7,4,9,1,3
Lets say user array has following elements input by user at console
user: 4,2,9,7,3
Now at first iteration the digit 7 at 0-th index of lottery array is matched to the digit 4 at 0-th index of user array. This index is specified using variable i. These means the first element of lottery array is matched with first element of user array. As these digits are not equal so they don't match and the variable i is incremented to point to the position of next digit.
Now at second iteration the digit 4 in lottery array is matched to the digit 2 of user array. As these digits are not equal so they don't match and the variable i is incremented.
at third iteration the digit 9 in lottery array is matched to the digit 9 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 1
Now at fourth iteration the digit 1 in lottery array is matched to the digit 7 of user array. As these digits are not equal so they don't match and the variable i is incremented. The value of match also remains the same i.e. 1
at fifth iteration the digit 3 in lottery array is matched to the digit 3 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 2
Next the loop ends because the value of exceeds 5 which is the size of the array.
Next if(match==size) statement has an if condition which checks if all digits match. This is checked by comparing the count of match variable to the size of the array. The value of match is 2 and value of size is 5 so this means that all the digits do not match. Hence this condition evaluates to false. So the statement in if part will not execute and program moves to the statement: cout<<"Number of digits matched: "<<match<<endl; which displays the value of match variable i.e. 2 as:
Number of digits matched: 2
followed by statement cout<<"Sorry! Better luck next time!" ; which displays the message:
Sorry! Better luck next time!

A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk and the profit of each carton of milk vary from farm to farm. Write a program that prompts the user to enter: The total amount of milk produced in the morning. The cost of producing one liter of milk. The profit on each carton of milk. The program then outputs: The number of milk cartons needed to hold milk. Round your answer to the nearest integer. The cost of producing milk. The profit for producing milk.
Answer:
milk_produced = float(input("Enter the total amount of milk produced in the morning: "))
liter_cost = float(input("Enter the cost of producing one liter of milk: "))
carton_profit = float(input("Enter the profit on each carton of milk: "))
carton_needed = round(milk_produced / 3.78)
cost = milk_produced * liter_cost
profit = carton_profit * carton_needed
print("The number of milk cartons needed to hold milk is " + str(carton_needed))
print("The cost of producing milk is " + str(cost))
print("The profit for producing milk is " + str(profit))
Explanation:
*The code is in Python.
Ask the user to enter milk_produced, liter_cost and carton_profit
Calculate the number of milk cartons needed, divide the milk_produced by the capacity (3.78) of a cartoon and round the result
Calculate the cost, multiply the milk_produced by liter_cost
Calculate the profit, multiply the carton_profit by carton_needed
Print the results
Write a program that prompts the user to input an integer that represents the money in cents. The program will the calculate the smallest combination of coins that the user has. For example, 42 cents is 1 quarter, 1 dime, 1 nickel, and 2 pennies. Similarly, 49 cents is 1 quarter, 2 dimes, and 4 pennies
Answer:
The program in Python is as follows:
cents = int(input("Cent: "))
quarter = int(cents/25)
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
dime = int(cents/10)
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
nickel = int(cents/5)
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
penny = cents - nickel * 5
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")
Explanation:
This line prompts user for input in cents
cents = int(input("Cent: "))
This line calculates the number of quarters in the input amount
quarter = int(cents/25)
This following if statement prints the calculated quarters
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
This line calculates the number of dime in the input amount
dime = int(cents/10)
This following if statement prints the calculated dime
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
This line calculates the number of nickels in the input amount
nickel = int(cents/5)
This following if statement prints the calculated nickels
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
This line calculates the number of pennies in the input amount
penny = cents - nickel * 5
This following if statement prints the calculated pennies
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")

Vulnerability of.
Explanation:
In this scenario, your network administrator finds a virus in the network software. Fortunately, she was able to eliminate it before it resulted in a denial-of-service attack, which would have prevented legitimate users of the networked database from gaining access to the records needed. It turns out that the network software did not have adequate security protections in place. The fact that this virus was successfully inserted into the network software points to a vulnerability of the network software.
In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Some of the ways to prevent vulnerability in a network are;
1. Ensure you use a very strong password with complexity through the use of alphanumerics.
2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.

Using computer software, compare the 2016 year-to-date sales through February to the 2017 year-to-date sales through February for each manufacturer by computing the difference. Using computer software, sort the list of the manufacturers in order of largest to smallest difference in year-to-date sales. Which manufacturers are in the top five with increased sales
Incomplete question. Here's a similar question found in the attachments.
Answer:
General Motors Corp, Chrysler, Ford Motor Company, Toyota Motors sales USA Inc, Nissan North America Inc.
Explanation:
By, using the MS Excel computer software, you would be able to compare the 2016 year-to-date sales through February 2017 year-to-date sales for each manufacturer.
Simply copy the data into the data cells of MS Excel, next use the =sum formula (which should have a minus sign; For example, =SUM (B5 - E5) would give you the difference between the 2016 sales and 2017 sales, only if sales for 2016 is found in column B row 5 and sales for 2017 in column E row 5).
Thus, the results obtained can further be evaluated to determine the manufacturers in the top five with increased sales.
Which of the following is NOT an advantage to using inheritance?
a. Code that is shared between classes needs to be written only once.
b. Similar classes can be made to behave consistently.
c. Enhancements to a base class will automatically be applied to derived classes.
d. One big superclass can be used instead of many little classes.
Answer:
D)One big superclass can be used instead of many little classes.
Explanation:
Inheritance could be described as getting new class on another existing class with almost same execution,
inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.
The advantages of using inheritance includes but not limited to
✓ Code that is shared between classes needs to be written only once.
✓Similar classes can be made to behave consistently.
✓ Enhancements to a base class will automatically be applied to derived classes.
A major disadvantage of inheritance is that child/children classes depends on parent class, hence a change in the parent class will affect the child class, therefore option C is the correction option.
Inheritance is a type of programming concept where by a class (Child) can inheritance methods, properties of another class (Parent).
Inheritance allows us to reuse of code, one advantage of Inheritance is that the code that is already present in base class need not be rewritten in the child class.
The different types of Inheritance are:
Single Inheritance.Multiple Inheritance.Multi-Level Inheritance.Hierarchical Inheritance.Hybrid Inheritance.Learn more:
