Answer:
a)
Account account = new Account();
b)
Account account = new Account(firstName, age);
c)
account.Age = newAge;
d)
int count = Account.Count;
Explanation:
a)
new is the keyword which is used to create an object.
Account is the class name.
account is the name of an object of class Account.
account object is created to access the class Account.
Account() is the constructor of Account class. This is the default constructor and it has no parameters. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.
b)
Account is the class name.
account is the name of an object of class Account.
Account() is the constructor of Account class. This is the parameterized constructor and it has two parameters i.e. firstName and age. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.
c)
account.Age = newAge;
Here account is the object name. The Age property to access and update the private field of the Account class is set to the variable named newAge.
d)
This int count = Account.Count; statement gets the value of a public static field named Count that’s defined in the Account class, and stores the value in a new int variable named count.

Add each element in origList with the corresponding value in offsetAmount. Print each sum followed by a space. Ex: If origList = {40, 50, 60, 70} and offsetAmount = {5, 7, 3, 0}, print:45 57 63 70 #include using namespace std;int main() {const int NUM_VALS = 4;int origList[NUM_VALS];int offsetAmount[NUM_VALS];int i = 0;origList[0] = 40;origList[1] = 50;origList[2] = 60;origList[3] = 70;offsetAmount[0] = 5;offsetAmount[1] = 7;offsetAmount[2] = 3;offsetAmount[3] = 0;// your solution goes here
Answer:
Complete the program with the following code segment
for(int i =0;i<=3;i++)
{
cout<<offsetAmount[i]+origList[i]<<" ";
}
return 0;
}
Explanation:
The following line is an iteration of variable i from 1 to 3; It iterates through elements of origList and offsetAmount
for(int i =0;i<=3;i++){
This adds and prints the corresponding elements of origList and offsetAmount
cout<<offsetAmount[i]+origList[i]<<" ";
} The iteration ends here

Write an interactive program to calculate the volume and surface area of a three-dimensional object.
Answer:
I am writing a Python program:
pi=3.14 #the value of pi is set to 3.14
radius = float(input("Enter the radius of sphere: ")) #prompts user to enter the radius of sphere
surface_area = 4 * pi * radius **2 #computes surface area of sphere
volume = (4.0/3.0) * (pi * radius ** 3) #computes volume of sphere
print("Surface Area of sphere is: ", surface_area) #prints the surface area
print("Volume of sphere is: {:.2f}".format(volume)) #prints the volume
Explanation:
Please see the attachment for the complete interactive code.
The first three lines of print statement in the attached image give a brief description of the program.
Next the program assigns 3.14 as the value of π (pi). Then the program prompts the user to enter the radius. Then it computes the surface area and volume of sphere using the formulas. Then it prints the resultant values of surface area and volume on output screen.
The psuedocode for this program is given below:
PROGRAM SphereVolume
pi=3.14
NUMBER radius, surface_area, volume
INPUT radius
COMPUTE volume = (4/3) * pi* radius ^3
COMPUTE surface_area = 4 * pi * radius ^ 2
OUTPUT volume , surface_area
END
Although Python provides us with many list methods, it is good practice and very instructive to think about how they are implemented. Implement a Python methods that works like the following: a. count b. in: return True if the item is in the list c. reverse d. index: return -1 if the item is not in the list e. insert
Answer:
Here are the methods:
a) count
def count(object, list):
counter = 0
for i in list:
if i == object:
counter = counter + 1
return counter
b) in : return True if the item is in the list
def include(object, list):
for i in list:
if i == object:
return True
return False
c) reverse
def reverse(list):
first = 0
last = len(list)-1
while first<last:
list[first] , list[last] = list[last] , list[first]
first = first + 1
last = last - 1
return list
d) index: return -1 if the item is not in the list
def index(object, list):
for x in range(len(list)):
if list[x] == object:
return x
return -1
e) insert
def insert(object, index, list):
return list[:index] + [object] + list[index:]
Explanation:
a)
The method count takes object and a list as parameters and returns the number of times that object appears in the list.
counter variable is used to count the number of times object appears in list.
Suppose
list = [1,1,2,1,3,4,4,5,6]
object = 1
The for loop i.e. for i in list iterates through each item in the list
if condition if i == object inside for loop checks if the item of list at i-th position is equal to the object. So for the above example, this condition checks if 1 is present in the list. If this condition evaluates to true then the value of counter is incremented to 1 otherwise the loop keeps iterating through the list searching for the occurrence of object (1) in the list.
After the complete list is moved through, the return counter statement returns the number of times object (i.e. 1 in the example) occurred in the list ( i.e. [1,1,2,1,3,4,4,5,6] ) As 1 appears thrice in the list so the output is 3.
b)
The method include takes two parameters i.e. object and list as parameters and returns True if the object is present in the list otherwise returns False. Here i have not named the function as in because in is a reserved keyword in Python so i used include as method name.
For example if list = [1,2,3,4] and object = 3
for loop for i in list iterates through each item of the list and the if condition if i == object checks if the item at i-th position of the list is equal to the specified object. This means for the above example the loop iterates through each number in the list and checks if the number at i-th position in the list is equal to 3 (object). When this if condition evaluates to true, the method returns True as output otherwise returns False in output ( if 3 is not found in the list). As object 3 is present in the list so the output is True.
c) reverse method takes a list as parameter and returns the list in reverse order.
Suppose list = [1,2,3,4,5,6]
The function has two variables i.e. first that is the first item of the list and last which is the last item of the list. Value of first is initialized to 0 and value of last is initialized to len(list)-1 where len(list) = 6 and 6-1=5 so last=5 for the above example. These are basically used as index variables to point to the first and last items of list.
The while loop executes until the value of first exceeds that of last.
Inside the while loop the statement list[first] , list[last] = list[last] , list[first] interchanges the values of elements of the list which are positioned at first and last. After each interchange the first is incremented to 1 and last is decremented to 1.
For example at first iteration:
first = 0
last = 5
list[0] , list[5] = list[5] , list[0]
This means in the list [1,2,3,4,5,6] The first element 1 is interchanged with last element 6. Then the value of first is incremented and first = 1, last = 4 to point at the elements 2 and 5 of the list and then exchanges them too.
This process goes on until while condition evaluates to false. When the loop breaks statement return list returns the reversed list.
d) The method index takes object and list as parameters and returns the index of the object/item if it is found in the list otherwise returns -1
For example list = [1,2,4,5,6] and object = 3
for loop i.e. for x in range(len(list)): moves through each item of the list until the end of the list is reached. if statement if list[x] == object: checks if the x-th index of the list is equal to the object. If it is true returns the index position of the list where the object is found otherwise returns -1. For the above examples 3 is not in the list so the output is -1
e) insert
The insert function takes as argument the object to be inserted, the index where the object is to be inserted and the list in which the object is to be inserted.
For example list = [0, 1, 2, 4, 5, 6] and object = 3 and index = 3
3 is to be inserted in list [1,2,4,5] at index position 3 of the list. The statement:
return list[:index] + [object] + list[index:]
list[:index] is a sub list that contains items from start to the index position. For above example:
list[:index] = [0, 1, 2]
list[index:] is a sub list that contains items from index position to end of the list.
list[index:] = [4, 5, 6]
[object] = [3]
So above statement becomes:
[0, 1, 2] + [3] + [4, 5, 6]
So the output is:
[0, 1, 2, 3, 4, 5, 6]
g Write a method that accepts a String object as an argument and displays its contents backward. For instance, if the string argument is "gravity" the method should display -"ytivarg". Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Answer:
The program written in C++ is as follows; (See Explanation Section for explanation)
#include <iostream>
using namespace std;
void revstring(string word)
{
string stringreverse = "";
for(int i = word.length() - 1; i>=0; i--)
{
stringreverse+=word[i];
}
cout<<stringreverse;
}
int main()
{
string user_input;
cout << "Enter a string: ";
getline (std::cin, user_input);
getstring(user_input);
return 0;
}
Explanation:
The method starts here
void getstring(string word)
{
This line initializes a string variable to an empty string
string stringreverse = "";
This iteration iterates through the character of the user input from the last to the first
for(int i = word.length() - 1; i>=0; i--) {
stringreverse+=word[i];
}
This line prints the reversed string
cout<<stringreverse;
}
The main method starts here
int main()
{
This line declares a string variable for user input
string user_input;
This line prompts the user for input
cout << "Enter a string: ";
This line gets user input
getline (std::cin, user_input);
This line passes the input string to the method
revstring(user_input);
return 0;
}

You are the network administrator for your company. A user reports that he cannot access network resources from his computer. He was able to access the resources yesterday. While troubleshooting his computer, you find that his computer is issued an Automatic Private IP Addressing (APIPA) address. All the network equipment in the user's computer is functioning properly because you are able to access the user's computer from a remote computer. What is most likely the problem
Answer:
the issued Automatic Private IP Addressing (APIPA) address.
Explanation:
Since we are told that the user was able to access the network resources yesterday, and all the network equipment in the user's computer is functioning properly, there is a very high possibility that because the user's computer has been issued an Automatic Private IP Addressing (APIPA) address, it affected his computer's ability to connect to a public network.
This is the case because private network IP addresses are known to prevent inflow and outflow of data onto public networks.

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:
• The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
• The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
• The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.
Demonstrate the class in a program that asks the user for the quantity of items being purchased and then displays the sale’s subtotal, amount of sales tax and total.
Answer:
Following are the code to this question:
import java.util.*; //import package for user input
class RetailItem//defining class RetailItem
{
private String desc;//defining String variable
private int unit;//defining integer variable
private double prices;//defining double variable
RetailItem()//defining default Constructor
{
//Constructor body
}
Output:
The Sub Total value: 199.75
The Sales Tax value: 11.985
The Total value: $211.735
Explanation:
In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.
In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.
In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

Answer:
The correct query is;
select * from EMPLOYEE where Employee_Name = 'JOE' or Employee_Name = 'Joe' or Employee_Name = 'joe';
where EMPLOYEE refer to the table name and type attribute name is Employee_Name
Explanation:
Here, the first thing we will do is to assume the name of the table.
Let’s assume the table name is EMPLOYEE, where the column i.e attribute from which we will be extracting our information is Employee_Name
The correct query to get the piece of information we are looking for will be;
select * from EMPLOYEE where Employee_Name = 'JOE' or Employee_Name = 'Joe' or Employee_Name = 'joe';
