Write a C++ program to find if a given array of integers is sorted in a descending order. The program should print "SORTED" if the array is sorted in a descending order and "UNSORTED" otherwise. Keep in mind that the program should print "SORTED" or "UNSORTED" only once.
Answer:
The cpp program for the given scenario is as follows.
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
//boolean variable declared and initialized
bool sorted=true;
//integer array declared and initialized
int arr[] = {1, 2, 3, 4, 5};
//integer variables declared and initialized to length of the array, arr
int len = std::end(arr) - std::begin(arr);
//array tested for being sorted
for(int idx=0; idx<len-1; idx++)
{
if(arr[idx] < arr[idx+1])
{
sorted=false;
break;
}
}
//message displayed
if(sorted == false)
cout<< "UNSORTED" <<endl;
else
cout<< "UNSORTED" <<endl;
return 0;
}
OUTPUT
UNSORTED
Explanation:
1. An integer array, arr, is declared and initialized as shown.
int arr[] = {1, 2, 3, 4, 5};
2. An integer variable, len, is declared and initialized to the size of the array created above.
int len = std::end(arr) - std::begin(arr);
3. A Boolean variable, sorted, is declared and initialized to true.
bool sorted=true;
4. All the variables and array are declared inside main().
5. Inside for loop, the array, arr, is tested for being sorted or unsorted. The for loop executes over an integer variable, idx, which ranges from 0 till the length of the array, arr.
6. The array is assumed to be sorted if all the elements of the array are in descending order.
7. If the elements of the array are in ascending order, the Boolean variable, sorted, is assigned the value false and for loop is exited using break keyword. The testing is done using if statement.
8. Based on the value of the Boolean variable, sorted, a message is displayed to the user.
9. The program can be tested for any size of the array and for any order of the elements, ascending or descending. The program can also be tested for array of other numeric data type including float and double.
10. All the code is written inside the main().
11. The length of the array is found using begin() and end() methods as shown previously. For this, the iterator header file is included in the program.
A(n) ________ is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Computers in a LAN are configured to use a symmetric key cipher within the LAN to avoid hardware address spoofing. This means that each computer share a different key with every other computer in the LAN. If there are 100 computers in this LAN, each computer must have at least:
a. 100 cipher keys
b. 99 cipher keys
c. 4950 cipher keys
d. 100000 cipher keys
Answer:
The correct answer is option (c) 4950 cipher keys
Explanation:
Solution
Given that:
From the given question we have that if there are 100 computers in a LAN, then each computer should have how many keys.
Now,
The number of computers available = 100
The number of keys used in symmetric key cipher for N parties is given as follows:
= N(N-1)/2
= 100 * (100 -1)/2
= 50 * 99
= 4950 cipher keys
In this assignment, you will develop a C++ program and a flowchart that calculates a cost to replace all tablets and desktop computers in a business. Customers paying cash get a ten percent discount applied to the total cost of the computers (desktop and tablets). Customers financing the purchase incur a fifteen percent finance charge based on the total cost of the computers (desktop and tablets). Tablets costs $320.00 each and desktops costs $800.00 each. The tax is 75% (.075).
Requirements:
⦁ Use the following variables of the appropriate type: name of company selling the computers, the cost per each type of computer, number of computers to be purchased, discount if paying cash, sales tax rate. Tablets =$320 each and desktop computers = $800.00 each. Sales Tax Rate = .075, Discount Percent = .10, and Finance Charge = .15.
⦁ Variable names must be descriptive.
⦁ Use additional variables to hold subtotals and totals.
⦁ For customers paying cash, the discount should be subtracted from the total computer cost.
⦁ For customers financing the purchase, the finance charge should be added to the total computer cost.
⦁ The body of your program must use variables only; there should not be any "hard coded" values in the output statements. An example of hardcoding is
***Cost of tablets = 4 * 320****.
⦁ Use cout to output the values of the variables to the console. Your cout statement MUST use the variables to display the values
⦁ Display the cost of the computers, tax and average cost per computer. The average cost will be the total cost divided by the number of computers purchased. Display the discount if the customer decides to pay cash or the finance charge if the customer finances the purchase.
⦁ Output must be labelled and easy to read as shown in the sample output below.
⦁ Program must be documented with the following:
⦁ // Name
⦁ // Date
⦁ // Program Name
⦁ // Description
⦁ Develop a flowchart
Hints:
Total cost of computers = cost per tablet * number of tablets purchased + cost per desktop * number of desktops purchased
Calculate the cost if paying cash or financing
Calculate the tax
Average cost per computer = Total computer cost divided by the number of computers purchased
Answer:

Transaction is an action or series of actions the execution of which should lead to a consistent database state from another consistent database state. Discuss which properties that transactions should have for their correct executions. Provide two examples to support your answer.
Explanation:
A transaction is a very small system unit that can contain many low-level tasks. A transaction in a database system should maintain, Atomicity, Consistency, Isolation, and Durability − these are commonly known as ACID properties − in order to ensure accuracy, completeness, and integrity of the data.
An example of a simple transaction is as below, Suppose a bank employee transfers Rs 500 from A's account to B's account.
A’s Account
Open_Account(A)
Old_Balance = A.balance
New_Balance = Old_Balance - 500
A.balance = New_Balance
Close_Account(A)
B’s Account
Open_Account(B)
Old_Balance = B.balance
New_Balance = Old_Balance + 500
B.balance = New_Balance
Close_Account(B)

For this project, you have to write 3 functions. C++
1. remove_adjacent_digits. This takes in 2 arguments, a std::vector, and a std::vector of the same size. You need to return a std::vector, where each of the strings no longer has any digits that are equal to, one more, or one less, than the corresponding integer in the 2nd vector.
2. sort_by_internal_numbers. This takes in a single argument, a std::vector, and you need to return a std::vector, which is sorted as if only the digits of each string is used to make a number.
3. sort_by_length_2nd_last_digit. This takes in a std::vector>. It returns a vector of the same type as the input, which is sorted, first by the length of the string in the pair, and if they are the same length, then the second last digit of the int.
See the test cases for examples of each of the above functions.
You need to submit a single file called main.cpp that contains all these functions. You can (and should) write additional functions as well. There is no need for a main function.
No loops (for, while, etc) are allowed. You must use only STL algorithms for this project.

The degree of a point in a triangulation is the number of edges incident to it. Give an example of a set of n points in the plane such that, no matter how the set is triangulated, there is always a point whose degree is n−1.
Answer:
squarepentagonExplanation:
The vertices of a square is one such set of points. Either diagonal will bring the degree of the points involved to 3 = 4-1.
The vertices of a regular pentagon is another such set of points. After joining the points in a convex hull, any interior connection will create a triangle and a quadrilateral. The diagonal of the quadrilateral will bring the degree of at least one of the points to 4 = 5-1.
Suppose you have 9 coins and one of them is heavier than others. Other 8 coins weight equally. You are also given a balance. Develop and algorithm to determine the heavy coin using only two measurements with the help of the balance. Clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
Answer:
Following are the algorithm to this question:
Find_Heavier_Coins(Coin[9]):
i) Let Coin[] Array represent all Coins.
ii) Divide coin[] into 3 parallel bundles and each has three coins, example 0-2, 3-5, 6-8 indicate a1 a2 a3
iii) Randomly select any two bundles and place them in balance [say a1 and a2]
iv) If Weigh of a1 and a2 has same:
// checking that if a3 has heavier coin
Choose any two 6-8 coins and place them onto balance [say 6 and 8]
If those who weigh has the same weight:
Third coin is coin heavier [say 7]
else:
The coin [6 or 8] is the one which is heavier on the balance
else:
//The coin has the package which would be heavier on the balance [say a1]
Select any two coins on balance from of the heavier package [say 0 and 1]
If they weigh the same weight:
Third coin is coin heavier [say 2]
else:
The coin that is heavier on the balance is the [or 0]
Explanation:
In the above-given algorithm code, a method Find_Heavier_Coins is declared which passes a coin[] array variable in its parameters. In the next step, if conditional block is used that checks the values which can be described as follows:
In the first, if block is used that checks a1 and a2 values and uses another if block in this it will print a3 value, else it will print 6 to 8 value. In the another, if the block it will check third coins value and prints its value if it is not correct it will print first coin valueProgramming CRe-type the code and fix any errors.

8 will be saved in variable c. This is only possible using the plus sign.
The plus sign also has other function such as string concatenation but this function is language dependent (i.e. some programming languages do not use + for string concatenation).
Conclusively, the built in function of the plus sign is for numeric addition
Look at these examples:- • Men are not emotional. • Women are too emotional. • Jewish people are good business people. • The French are great lovers. • Old people are useless. • Young people are sex mad. • Black people are poor. • Thin people are self-disciplined. • Fat people are clumsy. • Rock stars are drug addicts. To what extent do you agree with these statements? Make a note of which ones you agree with
Answer:
None
Explanation:
These are all stereotypes. Sure, there are definitely some people who fit their stereotypes, but not all. It's just a generalization at the end of the day. I can't really agree with any of them due to the fact that it's all stereotyping.
Perhaps you feel differently, and believe that some of these example are true. I can't though, sorry. Hope this take helps.
You are a network technician for a small corporate network that supports 1000 Mbps (Gigabit) Ethernet. The manager in the Executive Office says that his network connection has gone down frequently over the past few days. He replaced his Ethernet cable, but the connection problem has continued. Now his network connection is either down or very slow at all times. He wants you to install a new 1000 Mbps Ethernet network card in his workstation to see if that solves the problem.
If the new card does not resolve the issue, you will need to perform troubleshooting tasks to find the cause of the issue and confirm that the problem is fixed after you implement a solution. Following are some troubleshooting tasks you can try:
• Use the Network and Sharing Center and the ipconfig command on the Exec workstation to check for a network connection or an IP address.
• Look at the adapter settings to see the status of the Ethernet connection.
• Use the ping command to see if the workstation can communicate with the server in the Networking Closet. (See the exhibit for the IP address.)
• View the network activity lights for all networking devices to check for dead connections. In this lab, your task is to complete the following:
1. Install a new Ethernet adapter in one of the open slots in the Exec workstation per the manager's request.
2. Make sure that the new adapter is connected to the wall outlet with a cable that supports Gigabit Ethernet.
3. Resolve any other issues you find using the known good spare components on the Shelf to fix the problem and restore the manager's internet connection.
After you replace the network adapter and resolve the issues you found while troubleshooting, use the Network and Sharing Center to confirm that the workstation is connected to the network and the internet

Answer:
The step by step explanation
Explanation:
Before doing anything, the first thing to do is to select the 100BaseTX network adapter and reconnect the Cat5e cable. The 100BaseTX network adapter supports Fast
Ethernet which is all that is required.
Now do the following steps:
Step one
In Office 2, switch to the motherboard view of the computer (turning off the workstation as necessary).
Step two
On the Shelf, expand the Network Adapters category.
Step three
Identify the network adapter that supports Fast Ethernet 100BaseTX. Drag the network adapter from the Shelf to a
free PCI slot on the computer.
Step four
To connect the computer to the network, switch to the back view of the computer.
Step five
Drag the Cat5 cable connector from the motherboard's NIC to the port of the 100BaseTX network adapter.
Step six
To verify the connection to the local network and the Internet, switch to the front view of the computer.
Step seven
Click the power button on the computer case.
Step eight
After the workstation's operating system is loaded, click the networking icon in the notification area and click
Open Network and Sharing Center. The diagram should indicate an active connection to the network and the
Internet.
For one to be able to confirm the speed of the connection, it can be done by clicking the Local Area Connection link in the Network and
Sharing Center.
Java programing:
Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert)
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
/* Your solution goes here */
System.out.println("Testing completed");
return;
}
}
__________
Answer:
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
System.out.println("3, expecting 27, got: " + cubeNum(3));
System.out.println("-1, expecting -1, got: " + cubeNum(-1));
System.out.println("Testing completed");
return;
}
}
Explanation:
Added statements are highlighted.
Since the cubeNum function calculates the cube of the given number and we are asked to write two statements to test inputs 3 and -1, pass the parameters 3 and -1 to the function called cubeNum and print the results using print statements
