{
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
static double charge;
static double weight;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
do
{
System.out.print("Enter the weight of the package: ");
weight = sc.nextDouble();
if(weight<=0)
System.out.println("Invalid input value!");
}while(weight<=0);
if(weight<=2)
charge=wt_2;
else if(weight<=6 && weight>2)
charge=wt_6;
else if(weight<=10 && weight>6)
charge=wt_10;
else
charge=wt_more;
System.out.println("Shipping charges for the entered weight are $"+charge);
}
}
OUTPUT
Enter the weight of the package: 0
Invalid input value!
Enter the weight of the package: 4
Shipping charges for the entered weight are $3.0
Explanation:
1. The variables to hold all the shipping charges are declared as double and initialized.
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
2. The variable to hold the user input is declared as double.
static double charge;
static double weight;
3. The variable to hold the final shipping charge is also declared as double.
4. Inside main(), an object of Scanner class is created. This is not declared static since declared inside a static method, main().
Scanner sc = new Scanner(System.in);
5. Inside do-while loop, user input is taken until a valid value is entered.
6. Outside the loop, the final shipping charge is computed using multiple if-else statements.
7. The final shipping charge is then displayed to the user.
8. All the code is written inside class since java is a purely object-oriented language.
9. The object of the class is not created since only a single class is involved.
10. The class having the main() method is declared public.
11. The program is saved with the same name as that of the class having the main() method.
12. The program will be saved as ShippingCharge.java.
13. All the variables are declared as static since they are declared outside main(), at the class level.
When implementing a physical database from a logical data model, you must consider database performance by allowing data in the database to be accessed more rapidly. In order to increase data availability, the DBA may break up data that are accessed together to be stored together. Which method will improve the performance of this structure when running queries? What are advantages and disadvantages of this method?
Answer:
A method used to improve the performance of structure when running queries is known as Partitioning indexes.
The advantages of partitioning indexes are, It enables data management operations for example, index creation and rebuilding, It increases query performance.
The disadvantages are, one cannot define the primary index of partitioned table to be unique unless the whole partitioning column set is part of the primary index definition.
Explanation:
Solution
Partitioning indexes are known as b -tress indexes that shows hon how to break up the index into separate or different partitions.
Partitioning is usually done to enhance the performance and increased availability. when data are spread over multiple partitions, one can be able to operate on one partition without affecting others. i.e to run utilities, or to take data offline.
Almost all DBMS products support partitioning, but in various ways. we must be sure to know the nuances of an individual a particular DBMS execution before partitioning.
The advantages of Partitioned indexes are as follows:
It enables data management operations for example, index creation and rebuilding
It increases performance of query
It can significantly the impact of schedule downtime for maintenance operations
Disadvantages:
The primary index of partitioned table cannot be described to be unique except if the whole partitioning column set is part of the primary index definition.
Write a program that takes in an integer in the range 10 to 100 as input. Your program should countdown from that number to 0, printing
the count each of each iteration After ten numbers have been printed to the screen, you should start a newline. The program should stop
looping at 0 and not output that value
I would suggest using a counter to cổunt how many items have been printed out and then after 10 items, print a new line character and
then reset the counter.
important: Your output should use %3d" for exact spacing and a space before and after each number that is output with newlines in order
to test correctly. In C please
Answer:
The program written in C language is as follows
#include<stdio.h>
int main()
{
//Declare digit
int digit;
//Prompt user for input
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit);
//Check if digit is within range 10 to 100
while(digit<10 || digit >100)
{
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit);
}
//Initialize counter to 0
int counter = 0;
for(int i=digit;i>0;i--)
{
printf("%3d", i); //Print individual digit
counter++;
if(counter == 10) //Check if printed digit is up to 10
{
printf("\n"); //If yes, print a new line
counter=0; //And reset counter to 0
}
}
}
Explanation:
int digit; ->This line declares digit as type int
printf("Enter any integer: [10 - 100]: "); -> This line prompts user for input
scanf("%d", &digit);-> The input us saved in digit
while(digit<10 || digit >100) {
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit); }
->The above lines checks if input number is between 10 and 100
int counter = 0; -> Declare and set a counter variable to 0
for(int i=digit;i>0;i--){ -> Iterate from user input to 0
printf("%3d", i); -> This line prints individual digits with 3 line spacing
counter++; -> This line increments counter by 1
if(counter == 10){-> This line checks if printed digit is up to 10
printf("\n"); -> If yes, a new line is printed
counter=0;} -> Reset counter to 0
} - > End of iteration

Consider the following concurrent tasks, in which each assignment statement executes atomically. Within a task, the statements occur in order. Initially, the shared variables x and y are set to 0.
Task 1 Task 2
x = 1 y = 1
a = y b = x
At the end of the concurrent tasks, the values ofa andb are examined. Which of the following must be true?
I. ( a == 0 ) ( b == 1 )
II. ( b == 0 ) ( a == 1 )
III. ( a == 1 ) ( b == 1 )
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
Answer:
(D) I and II only
Explanation:
Concurrent tasks is when there is more than one task to be performed but the order of the task is not determined. The tasks occur asynchronously which means multiple processors occur execute input instruction simultaneously. When x =1 and y = 1, the concurrent task will be performed and the a will be zero or either 1.
In which contingency plan testing strategy do individuals follow each and every IR/DR/BC procedure, including the interruption of service, restoration of data from backups, and notification of appropriate individuals?
a. Full-interruption
b. Desk check
c. Simulation
d. Structured walk-through
Answer:Full-interruption--A
Explanation: The Full-interruption is one of the major steps for a Disaster Recovery Plan, DRP which ensures businesses are not disrupted by saving valuable resources during a disaster like a data breach from fire or flood.
Although expensive and very risky especially in its simulation of a disruption, this thorough plan ensures that when a disaster occurs, the operations are shut down at the primary site and are transferred to the recovery site allowing Individuals follow every procedure, ranging from the interruption of service to the restoration of data from backups, also with the notification of appropriate individuals.

A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0' otherwise. A low battery signal, which is '0' if the laptop's battery has reached an almost empty state, and '1' otherwise. Suppose the laptop's power control system accepts a single hibernate signal which determines if the laptop should change its current operating state and shut down. If the laptop should shut down when the battery is low and its charger is unplugged, which gate could be used to produce the hibernate signal?
Answer:
The correct usage is a NOR gate which is indicated in the explanation.
Explanation:
The truth table for the given two signals, namely
p=unplugged signal
q=low battery signal
can form a truth table of following form
Here p has 2 states
1 if the power supply is connected
0 otherwise
Similarly q has 2 states
0 if the battery has reached almost zero state
1 otherwise
As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.
Using this condition, the truth table is formed as
unplugged signal | low battery signal | Hibernate Signal
0 | 0 | 1
0 | 1 | 0
1 | 0 | 0
1 | 1 | 0
Now the truth table of NOR is given as
a | b | a or b | ~(a or b)
0 | 0 | 0 | 1
0 | 1 | 1 | 0
1 | 0 | 1 | 0
1 | 1 | 1 | 0
This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.
The following numbers are inserted into a linked list in this order:
10, 20, 30, 40, 50, 60
What would the following statements display?
pCur = head->next;
cout << pCur->data << " ";
cout << pCur->next->data << endl;
a) 20 30
b) 40 50
c) 10 20
d) 30 40
Answer:
A. 20 30
Explanation:
Given
Linked list: 10, 20, 30, 40, 50, 60
Required
The output of the following code segment
pCur = head->next;
cout << pCur->data << " ";
cout << pCur->next->data << endl;
A linked list operates by the use of nodes which begins from the head to the next node, to the next, till it reaches the last;
The first line of the code segment; "pCur = head->next; " shifts the node from the head to the next node
The head node is the node at index 0 and that is 10;
This means that the focus has been shifted to the next at index 1 and that is 20;
So, pCur = 20
The next line of the code segment; cout << pCur->data << " "; prints pCur and a blank space
i.e. "20 " [Take note of the blank space after 20]
The last line "cout << pCur->next->data << endl; " contains two instructions which are
1. pCur = next->data;
2. cout<<pCur->data;
(1) shifts focus to the next node after 20 ; This gives pCur = 30
(2) prints the value of pCur
Hence, the output of the code segment is 20 30

Describe and list advantages and disadvantages of each of the following backup types:
full, differential, incremental, selective, CPD, and cloud.
Answer:
Full back up
It creates complete copy of the source of data. This feature made it to the best back up with good speed of recovery of the data and simplicity.However, because it is needed for backing up of a lot of data, it is time consuming process,Besides it also disturbs the routine application of the technologist infrastructure. In addition large capacity storage is needed for the storage of the large volume of back up with each new creation.
Incremental back up: back up work at high speed thus saves time, Little storage capacity is needed. This type of back up can be run as many time as wished.
However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.
Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.
The selective back up enable selection of certain type of file or folders for back up.
it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.
CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.
Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.
However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.

Answer:
#Declare variable to get the input
#list from the user
input_list = input()
#split the list into words by space
list = input_list.split()
#Begin for-loop to iterate each word
#to get the word frequency
for word in list:
#get the frequency for each word
frequency=list.count(word)
#print word and frequency
print(word,frequency)
Explanation:
This program that we are told to write will be done by using python programming language/ High-level programming language.
The question wants us to write a program in which the output will be as below;
hey 1
hi 2
Mark 1
hi 2
mark 1
Just by imputing hey hi mark hi mark.
Just copy and run the code below.
#Declare variable to get the input
#list from the user
input_list = input()
#split the list into words by space
list = input_list.split()
#Begin for-loop to iterate each word
#to get the word frequency
for word in list:
#get the frequency for each word
frequency=list.count(word)
#print word and frequency
print(word,frequency)
In this exercise we have to use the knowledge in computational language in python to write the following code:
We have the code can be found in the attached image.
So in an easier way we have that the code is
input_list = input()
list = input_list.split()
for word in list:
frequency=list.count(word)
print(word,frequency)

A new operating system uses passwords that consist of three characters. Each character must be a digit between 0 and 9. For example, three distinct possible passwords are 123, 416, and 999. The system uses 32-bit salt values. The system also allows one login attempt every second and never locks out users regardless of how many failed attempts occur. If an adversary has obtained a copy of the password file and conducts an offline brute-force attack by trying every password combination until the adversary obtains username and password combination. The use of a 32-bit salt value
Answer:
Brute force is technique that is used for cracking password
In this case the system uses only three characters(0-9). By applying Brute force attack in "hit and try" manner we easily crack the password.
Explanation:
Solution
There are a wide variety of password cracking mechanisms.Brute force is one of the popular password cracking technique.Brute force attack is generally used to crack small passwords.
In the given example the system uses only three characters(0-9).By using Brute force attack in "hit and try" manner we easily crack the password.There are only 10 possible passwords for this type of system.Because we can arrange 0-9 only in 10 ways.But for Systems with long passwords it is difficult to find it in hit and try manner.But instead of having plain password each password have a random salt value.
In a system of 32 bit salt value there are 2^32 different key values.
By increasing the salt value from 32 bits to 64 bits there are 2^64 different key values.It increases the time taken to crack a password for an attacker.so by changing salt value from 32 to 64 bits will make it more harder for the adversary's attack to be successful.

C++ Problem: In the bin packing problem, items of different weights (or sizes) must be packed into a finite number of bins each with the capacity C in a way that minimizes the number of bins used. The decision version of the bin packing problem (deciding if objects will fit into <= k bins) is NPcomplete. There is no known polynomial time algorithm to solve the optimization version of the bin packing problem. In this homework you will be examining three greedy approximation algorithms to solve the bin packing problem.
- First-Fit: Put each item as you come to it into the first (earliest opened) bin into which it fits. If there is no available bin then open a new bin.
- First-Fit-Decreasing: First sort the items in decreasing order by size, then use First-Fit on the resulting list.
- Best Fit: Place the items in the order in which they arrive. Place the next item into the bin which will leave the least room left over after the item is placed in the bin. If it does not fit in any bin, start a new bin.
Implement the algorithms in C++. Your program named bins.cpp should read in a text file named bin.txt with multiple test cases as explained below and output to the terminal the number of bins each algorithm calculated for each test case. Example bin.txt: The first line is the number of test cases, followed by the capacity of bins for that test case, the number of items and then the weight of each item. You can assume that the weight of an item does not exceed the capacity of a bin for that problem.

The following if statement uses an overloaded > operator to determine whether the price of a Car object is more than $5000. Car is a struct and myCar is an object of Car. Each Cor object has two variables: id (int) and price (float). As you can see in the following code, the ID of myCar is 12345 and the price is $6,000. Car myCar - [12345, 6000.); float price - 5000; if (myCar > price) cout << "My car price is more than $5,000/n": Which one of the following function prototypes is correct syntax to overload the > operator based on the if statement above. void operator> float price: O bool operator>(Car & car, float price): bool operator (float amt): bool operator> Car & your Car): None of the above
Answer:
The correct syntax to overload is bool operator (float amt): so, the third statement is right.
Explanation:
Solution
From the given question we have to find which statements is correct for the following function prototype.
Now,
Since the price of a Car object is above $5000, the car here is considered a struct and myCar is an object of Car
Both Car object consists of two variables which are id (int) and price (float)
Thus, from the given example the corresponding code says that the ID of myCar is represented as follows:
myCar - [12345, 6000);
The float price = 5000
Then,
cout << "My car price is more than $5,000/n"
Therefore the following statement bool operator (float amt): is the right syntax to overload.
During an investigation of a cybercrime, the law enforcement officers came across a computer that had the hard drive encrypted. Chose the best course of action they should take to access the data on that drive.
a. Use image filtering techniques to see what's behing the encrypted files.
b. Try to convince the owner of the computer to give you to decryption key/password.
c. Identify the encryption algorithm and attempt a brute force attack to get access to the file.
d. Disconnect the hard drive from power so the encryption key can be exposed on the next power up.
e. Try to copy the drive bit by bit so you can see the files in each directory.
Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
Three examples of parameter-parsing implementation models are: (1)________, (2)________, and (3)________.
Answer:1) Parse-by-value
2) Parse-by-reference
3) Parse-by-name
Explanation: Parameter parsing refers to a communication among procedures or functions.
The values of a variable procedure are transferred to the called procedure by some mechanisms. Different techniques of parameter-parsing include; parse-by-value, parse-by-reference, parse-by-copy restore, parse-by-name.

1. Implement the function dict_intersect, which takes two dictionaries as parameters d1 and d2, and returns a new dictionary which contains only those keys which appear in both d1 and d2, whose values are a tuple of the corresponding values from d1 and d2.
E.g., dict_intersect({'a': 'apple', 'b': 'banana'}, {'b': 'bee', 'c': 'cat'}) should return {'b': ('banana', 'bee')}
2. Implement the function consolidate, which accepts zero or more sequences in the star parameter seqs, and returns a dictionary whose keys consist of values found in those sequences, which in turn map to numbers indicating how many times each value appears across all the sequences.
E.g., consolidate([1,2,3], [1,1,1], [2,4], [1]) should return the dictionary {1: 5, 2: 2, 3: 1, 4: 1}.
Answer:
1
def dict_intersect(d1,d2): #create dictionary
d3={} #dictionaries
for key1,value1 in d1.items(): #iterate through the loop
if key1 in d2: #checking condition
d3[key1]=(d1[key1],d2[key1]) #add the items into the dictionary
return d 3
print(dict_intersect({'a': 'apple', 'b': 'banana'}, {'b': 'bee', 'c': 'cat'})) #display
2
def consolidate(*l1): #create consolidate
d3={} # create dictionary
for k in l1: #iterate through the loop
for number in k: #iterate through the loop d3[number]=d3.get(number,0)+1 #increment the value
return d 3 #return
print(consolidate([1,2,3], [1,1,1], [2,4], [1])) #display

Following are the description of program
Create a dictionary i.e"dict_intersect(d1,d2) " in this dictionary created a dictionary d3 .After that iterated the loop and check the condition .If the condition is true then add the items into the dictionary and return the dictionary d3 .Finally print them that are specified in the given question .2
Following are the description of program
Create a dictionary consolidate inside that created a dictionary "d3" .After that iterated the loop outer as well as inner loop and increment the value of items .Return the d3 dictionary and print the dictionary as specified in the given question .
Write a program that lets the Michigan Popcorn Company keep track of their sales for seven different types of popcorn they produce: plain, butter, caramel, cheese, chocolate, turtle and zebra. It should use two parallel seven-element arrays: an array of strings that holds the seven popcorn names and an array of integers that holds the number of bags of popcorn sold during the past month for each popcorn flavor. The names should be stored using an initialization list at the time the flavors array is created. The program should prompt the user to enter the number of bags sold for each flavor. Once the popcorn data has been entered, the program should produce a report for each popcorn type, total sales, and the names of the highest selling and lowest selling products. Be sure to include comments throughout your code where appropriate. Complete the C++ code using Visual Studio or Xcode, compress (zip) and upload the entire project folder to the Blackboard assignment area by clicking on the Browse My Computer button or by dragging the file inside the Attach Files box g
Answer:
#include <iostream>using namespace std;int main(){ // declare and initialize popcorn name array string popcorn_name[7] = {"plain", "butter", "caramel", "cheese", "chocolate", "turtle", "zebra"}; // declare and initialize sales array with 7 elements int sales[7]; // A loop to prompt user to enter sales for each popcorn for(int i=0; i < 7; i++){ cout<<"Enter number of sales for " + popcorn_name[i] + " :"; cin>>sales[i]; } // Find maximum sales int max = sales[0]; int maxIndex = 0; for(int j=1; j < 7; j++){ if(max < sales[j]){ max = sales[j]; maxIndex = j; } } // Find minimum sales int min = sales[0]; int minIndex = 0; for(int k=1; k < 7; k++){ if(min > sales[k]){ min = sales[k]; minIndex = k; } } // Print popcorn name and sales for(int l=0; l < 7 ; l++){ cout<<popcorn_name[l]<<"\n"; cout<<"Sales: "<< sales[l]<<"\n\n"; } // Print popcorn name with maximum and minimum sales cout<<"Highest selling: "<< popcorn_name[maxIndex]<<"\n"; cout<<"Lowest selling: "<<popcorn_name[minIndex]<<"\n"; return 0;}Explanation:
Create two arrays to hold the list of popcorn name and their sales (Line 5-8). Next prompt user to input the sales for each popcorn (Line 10-14). Get the maximum sales of the popcorn (Line 17-24) and minimum sales (Line 27-34). Print the popcorn name and sales (Line 37-40) and the popcorn name with highest and lowest selling (Line 43-44).
