Write a function which sorts the queue in order from the smallest value to the largest value. This should be a modified version of bubble sort.
Answer:
#include <iostream>
using namespace std;
void swap(int *a,int *b){ //function to interchange values of 2 variables
int temp=*a;
*a=*b;
*b=temp;
}
void sort(int queue[],int n)
{
int i,j;
for(i=0;i<n;i++) //to implement bubble sort
{
for(j=0;j<n-i-1;j++)
{
if(queue[j]>queue[j+1])
swap(queue[j],queue[j+1]); //to swap values of these 2 variables
}
}
}
int main()
{
int queue[]={6,4,2,9,5,1};
int n=sizeof(queue)/4; //to find length of array
sort(queue,n);
for(int i=0;i<n;i++)
cout<<queue[i]<<" ";
return 0;
}
OUTPUT :
1 2 4 5 6 9
Explanation:
In the above code, Queue is implemented using an array and then passed to a function sort, so that the queue can be sorted in ascending order. In the sort function, in each pass 2 adjacent values are compared and if lower index value is greater than the higher one they are swapped using a swap function that is created to interchange the values of 2 variables.
An organization is granted the block 130.56.0.0/16. The administrator wants to create 1024 subnets.
A. Find the subnet mask.
B. Find the number of addresses in each subnet.
C. Find the first and last addresses in subnet 1.
D. Find the first and last addresses in subnet 1024.
Answer:
A. 255.255.255.192
B. 62 address
C. First 130.56.0.1 and last 130.56.0.62
D. First 130.56.255.193 and last 130.56.255.254
Explanation:
A. We have a class b address, we know that because end in 130.56.0.0/16
We want 1024 subsets this is equal 2^10 = 1024.
Then we sum both decimal number 10 + 16 = 26, we can represent in subnet mask like 255.255.255.192.
B. We already have used 26 bits, in total 32, we must use the rest of the bits for the address
32 - 26 = 6
2^6 = 64, but we use two per subnet cannot be allocated and subnet mask.
We have in total 62 address.
C. We have 62 address for logic the last address is 130.56.0.62, and the first one is 130.56.0.1, because we cannot use the 130.56.0.0
D. We could represent these address from this mask 255.255.255.192 where First address is 130.56.255.193 and the last 130.56.255.254.

2. Penetration testing is a particularly important contributor to the incident management process. Explain why that is the case, and provide examples of how penetration test results can be used to improve the incident response process.
Any test practices end-user he or she does by step by step process for quality testing. Some end-user will have a checklist to do while testing any software or hardware installing.
A hacking end-user has to do the test process if he or she has to follow some steps during testing.
Explanation:
This process is called penetration testing, in other words, it is called pen-testing.
1. In the digital world, security plays an important role. Before any potential incidents taking place, security threats have to handle properly. Before hacking takes place for pc or workstation or desktop, the end-user has to identify and take proper action.
Mostly all threats happen in c:\users\appdata folder in windows operating system
2. Penetration testing is used to for hacking purpose testing.
a. Step by step method is followed.
b. Best practice testing on network security, computer system, web system and find vulnerability check.
c. The pen test method is involved in legal achievements on network
d. To identify vulnerability assessment inside a network
Identifying threats through potential incidents is key to proactively securing systems against cyber-attacks. Penetration testing plays a crucial role by uncovering vulnerabilities and informing incident response enhancements, ultimately strengthening an organization's security framework.
Importance of Threat Identification in Security
Identifying potential incidents, which represent threats that have not yet occurred, is critical for maintaining security. Identifying a threat helps in proactive risk management, allowing organizations to implement protective measures before an incident occurs. Recognizing threats is essential because it allows for the design of robust systems that can defend against potential cyber-attacks and avoid vulnerabilities that could be exploited.
Role of Penetration Testing in Incident Management
Penetration testing is a simulated cyberattack used to test the robustness of a system against real-world attack scenarios. By finding and exploiting vulnerabilities, security analysts can identify weak points in an organization's networks and systems. Results from penetration testing can then inform improvements in the incident response process, by recommending security enhancements to mitigate identified risks, and by preparing organizations to respond more effectively to future incidents.
Utilization of Penetration Testing Results
The use of penetration test results is integral in strengthening the incident response process. By understanding the vulnerabilities and the methods by which a system can be compromised, organizations can better plan for and respond to incidents, thus enhancing their overall security posture. Furthermore, penetration testing educates users about security practices, contributes to the continuous surveillance and upgrading of security infrastructure, and underlines the importance of avoiding complacency in cybersecurity.
_____ allow you to logically separate ports in switches to create subdomains without wiring your network as physical subdomains. This is particularly helpful in office situations where seating does not determine the role of the user.
Answer:
The correct answer for the following question is VLAN.
Explanation:
It stands for Virtue Logical Area Network which allows you to group port on a switch logically. VLANs can be extend across (a period of time) multiple switches means you used to express on port that you're in that VLAN by changing the VLAN number.
We have the ability to improve our security with VLANs by controlling what VLAN is accessing with the other network of VLANs. So that this network is particularly helpful in office situation to create subdomain without wiring physical domain as your network.
What does the following loop do?int[] a = {6, 1, 9, 5, 12, 3};int len = a.length;int x = 0;for (int i = 0; i < len; i++)if (a[i] % 2 == 0) x++;System.out.println(x);1. Sums the even elements in a.2. Finds the largest value in a.3. Counts the even elements in a.4. Finds the smallest value in a.
Answer:
The answer is "Option 3"
Explanation:
The description of the above java code can be given as:
In the given code an array initialized elements in the next line an integer variable that is "len" is define this variable holds a length of the array and another variable "x" is defined that holds value 0. Then we use loop in loop a conditional statement is used that checks in array if any number is even. If this condition is true so the value of x variable increases by 1 and prints its value.A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt
Answer:
Python file with appropriate comments given below
Explanation:
#Take the input file name
filename=input('Enter the input file name: ')
#Open the input file
inputFile = open(filename,"r+")
#Define the dictionary.
list={}
#Read and split the file using for loop
for word in inputFile.read().split():
#Check the word to be or not in file.
if word not in list:
list[word] = 1
#increment by 1
else:
list[word] += 1
#Close the file.
inputFile.close();
#print a line
print();
#The word are sorted as per their ASCII value.
fori in sorted(list):
#print the unique words and their
#frequencies in alphabetical order.
print("{0} {1} ".format(i, list[i]));
The program which produces a sorted output of words and frequency based on a read on text file is written in python 3 thus :
filename = input('Enter the your file name : ')
#accepts user input for name of file
input_file = open(filename,"r+")
#open input file in read mode
list= dict()
#initialize an empty dictionary
for word in input_file.read().split():
#Read each line and split the file using for loop
if word not in list:
list[word] = 1
#increment by 1
else:
list[word] += 1
#if word already exists in dictionary increase frequency by 1, if not assign a frequency of 1
input_file.close();
#close the file
for i in sorted(list):
print("{0} {1} ".format(i, list[i]));
#loop through and display the word and its corresponding frequency

Consider the following base and derived class declarations: class BaseClass { public: void BaseAlpha(); private: void BaseBeta(); float baseField; }; class DerivedClass : public BaseClass { public: void DerivedAlpha(); void DerivedBeta(); private: int derivedField; }; For each class, do the following:
a) List all private data members.
b) List all private data members that the class's member functions can reference directly.
c) List all functions that the class's member functions can invoke.
d) List all member functions that a client of the class may invoke.
Final answer:
The private data members of BaseClass and DerivedClass are baseField and derivedField, respectively. Member functions of BaseClass can directly reference baseField and call BaseAlpha(), while DerivedClass member functions can access derivedField and can invoke DerivedAlpha(), DerivedBeta(), and the inherited BaseAlpha(). Clients may call BaseAlpha() for BaseClass and DerivedAlpha(), DerivedBeta(), and the inherited BaseAlpha() for DerivedClass.
Explanation:
Private Data Members and Member Functions in C++ Classes
In the given C++ classes, the private data members and member functions that can be accessed are:
BaseClass
a) Private data members: float baseField
b) Can reference directly: float baseField
c) Member functions can invoke: void BaseAlpha()
d) Client may invoke: void BaseAlpha()
DerivedClass
a) Private data members: int derivedField
b) Can reference directly: int derivedField
c) Member functions can invoke: void DerivedAlpha(), void DerivedBeta(), and inherited void BaseAlpha()
d) Client may invoke: void DerivedAlpha(), void DerivedBeta(), and inherited void BaseAlpha()
Note that private member functions are not listed as they cannot be accessed outside of the class definition. Also, the derived class has access to all of its own members as well as the public and protected members of its base class.

Following are the program in c++ language
#include <iostream> // header file
using namespace std; // namespace
void largest(int a[], int size); // function declaration
int main() // main method
{
int arr[30],n,count1=0; // variable declaration
cout<<" enter the size elements in array:";
cin>>n; // read the input by user
cout<<"enter array elements:";
for(int k=0;k<n;k++) // iterating over the loop
cin>>arr[k]; // read the elements in the array
largest(arr,n); // calling function largest
return 0;
}
void largest(int a[], int n1) // function definition
{
int i, maximum, second,count=0; // variable declaration
if(n1<2) // checkiing the condition
{
cout<<"invalid input"; // print the message
return;
}
else
{
maximum =INT8_MIN; // store the minimum value of an object
second=INT8_MIN; //store the minimum value of an object
for(i = 0;i<n1; i ++) // iterating over the loop
{
if (a[i]>maximum) // comparing the condition
{
second = maximum; // store the maximum value in the second variable
maximum = a[i];
count++; // increment the count
}
else if (a[i] > second && a[i] != maximum)
{
second = a[i];
count++;
}
}
}
if(count<2)
{
cout<<"Maximum value:"<<maximum; // display the maximum value
cout<<" all the value are equal";
}
else

Explanation:
Following are the description of program
In this program, we create a function largest which calculated the largest and the second largest element in the array.Firstly check the size of elements in the if block. If the size is less then 2 then an invalid messages will be printed on console otherwise the control moves to the else block.In the else block it stores the minimum value of an object in a maximum and second variable by using INT8_MIN function. After that iterating the loop and find the largest and second-largest element in the array .In this loop, we used the if-else block and find the largest and second-largest element.Finally, print the largest and second-largest elements in the arrayAssume all memory accesses are cache hit. 20% of the Load instructions are followed by a dependent computational instruction, and 30% of the computational instructions are also followed by a dependent computational instruction. 20% of the branch instructions are unconditional, while 80% are conditional. 40% of the conditional branches are taken, 60% are not taken. The penalty for taking the branch is one cycle. If data forwarding is allowed, what is the instruction throughput for pipelined execution?

Using Structured Query Language (SQL), create a query that gets the following data from the sakila database:
Actor Last Name, Actor First Name, Film Title
For all actors with a last name that begins with M
In alphabetical order by Actor's Last Name
Queries to get data from sakila database using Structured Query Languange (SQL):
Assuming that you have created a Database already, with tables in it, containing at least 50 records and these fields:
ACTOR_LASTNAME, ACTOR_FIRSTNAME, FILM_TITLE
Take note that the database and table name is both "sakila".
1. We can fetch, display or get data using SELECT command or query. Let's type the command like this:
SELECT ACTOR_LASTNAME, ACTOR_FIRSTNAME, FILM_TITLE FROM sakila
The command above is called SELECT command that would allow you to display records inside your table. Normally SQL programmers would execute SELECT * command, but since we are just required to display three (3) columns only, then we could just select the column names for our data display. Your columns are: SELECT ACTOR_LASTNAME, ACTOR_FIRSTNAME and FILM_TITLE.
2. For the second command or query, we can execute this:
SELECT ACTOR_LASTNAME FROM sakila WHERE ACTOR_LASTNAME 'M%' ORDER BY ACTOR_LASTNAME .
The select where command is like a conditional statement (IF). Where is the statement used to display ACTOR_LASTNAME field starting with letter M. The ORDER BY command is the arrangement of the names in alphabetical order.

Explanation:
Here, we define a function "sum()" and pass an argument "tu" which stores the tuple type value, inside the function.
Set the if conditional statement to check condition is the length of the tuple is 0 then, return 0.Otherwise, call and return the sum of the tuple which is recursively calculated and close the function.Finally, set the tuple type variable "tu" and initialize the value in it then, print and call the function sum.
Final answer:
A recursive function in Python can be written to calculate the sum of the elements of a tuple by adding the first element to the sum of the remaining elements until an empty tuple is reached, which has a sum of 0.
Explanation:
In Python, tuples are immutable sequences of elements, typically used to store collections of heterogeneous data. A recursive function for summing the elements of a tuple can be defined by considering the base case of an empty tuple having a sum of 0. If the tuple is not empty, the sum is computed by adding the first element of the tuple to the sum of the remaining tuple elements.
The recursive function defined below takes a tuple as an argument and calculates the sum of its elements:
def sum_of_elements(a_tuple):
if not a_tuple: # Base case: empty tuple
return 0
else:
return a_tuple[0] + sum_of_elements(a_tuple[1:]) # Recursive case
This recursive approach is an example of how tuples can be processed in Python. It leverages the fact that tuples can be indexed and sliced, and we are able to recursively reduce the problem size by considering the tuple without its first element.
If you pass the array ar to the method m() like this, m(ar); the element ar[0] :
A. will be changed by the method m()
B. cannot be changed by the method m()
C. may be changed by the method m(), but not necessarily
D. None of these
Answer: (B)
Explanation:
Any changes on array made inside the function m() will only affect the ar[] present inside the function that means its scope is only within the function. The original array ar[] outside the fuction's scope won't change.
Give pseudocode for an algorithm that removes all negative values from an array, preserving the order of the remaining elements.
Answer:
Begin.
WRITE ''enter test array''
READ test array
test [ ] = new_int [ ] { enter test array here, separated by comma}
int [ ] positives = Arrays.stream(test). filter(x -> x >= 0).toArray();
System. out. println( " Positive array");
for (int i : positives) {
System.out.print(i+ "\t"); }
WRITE positive array
End

The pseudocode for the alogirithm has been simplified above, it is implemented in Java 8
Describe how tuples can be useful with loops over lists and dictionaries, and give Python code examples. Create your own code examples.
Answer:
The explained gives the merits of tuples over the lists and dictionaries.
Explanation:
Tuples can be used to store the related attributes in a single object without creating a custom class, or without creating parallel lists..
For example, if we want to store the name and marks of a student together, We can store it in a list of tuples simply:
data = [('Jack', 90), ('Rochell', 56), ('Amy', 75)]
# to print each person's info:
for (name, marks) in data:
print(name, 'has', marks, 'marks')
# the zip function is used to zip 2 lists together..
Suppose the above data was in 2 parallel lists:
names = ['Jack', 'Rochell', 'Amy']
marks = [90, 56, 75]
# then we can print same output using below syntax:
for (name, marks) in zip(names, marks):
print(name, 'has', marks, 'marks')
# The enumerate function assigns the indices to individual elements of list..
# If we wanted to give a index to each student, we could do below:
for (index, name) in enumerate(names):
print(index, ':', name)
# The items method is used in dictionary, Where it returns the key value pair of
# the dictionary in tuple format
# If the above tuple list was in dictionary format like below:
marksDict = {'Jack': 90, 'Rochell': 56, 'Amy': 75}
# Then using the dictionary, we can print same output with below code:
for (name, marks) in marksDict.items():
print(name, 'has', marks, 'marks')
Tuples are useful for looping over lists and dictionaries because of their immutability and hashable properties. They help maintain data integrity and efficiency.
Tuples are immutable sequences in Python, and they are often used when looping over lists and dictionaries to maintain data integrity and utilize their hashable properties in dictionaries.
Here are some examples,
Looping with Tuples Over Lists
When looping over a list of tuples, you can easily unpack the elements for use within the loop.
Here's a simple example,
students = [("John", 85), ("Jane", 92), ("Dave", 78)]
for name, score in students:
print(f"Student: {name}, Score: {score}")
This code will output:
Student: John, Score: 85
Student: Jane, Score: 92
Student: Dave, Score: 78
Looping with Tuples Over Dictionaries
In dictionaries, tuples can be useful as keys because they are immutable and hashable. You can also convert dictionary items into tuples to easily iterate over them.
Here's an example,
grades = {"John": 85, "Jane": 92, "Dave": 78}
for name, score in grades.items():
print(f"Student: {name}, Score: {score}")
This code will produce the same output as the previous example. Using tuples in this way helps preserve data integrity and allows for efficient key-value pair iteration.
What kind of app or technology would you like to create? Why ?
Answer:
i would like to create an app that reminds old people or people with cancer to take their medications....
Explanation:
why: i would like to make this because my friends sister was 7 and had died from cancer due to not taking her medication...also i would like to because older people tend to forget or the have Alzheimer Disease and/or dementia and they cant remember to take their pills.
