When passing a stream to a function, it must always be pass-by-__________.
a) value
b) address
c) reference
d) class
e) function
Answer:
C) Reference
Explanation:
Stream objects are usually passed to functions as parameters, similar to other kind of objects. When passing a stream parameter, it must always be pass-by-reference.
This means that a reference to the original object is being passed to the function and not the copy of the object. As such, the object can be modified within the function. Also, if the object is large or has a large memory, copying it may be inefficient as regards the memory space and the time.
Therefore, object references point to the same object even when they are passed to functions.

Consider a set A = {a1, . . . , an} and a collection B1, B2, . . . , Bm of subsets of A (i.e., Bi ⊆ A for each i). We say that a set H ⊆ A is a hitting set for the collection B1, B2, . . . , Bm if H contains at least one element from each Bi – that is, if H ∩ Bi is not empty for each i (so H "hits" all the sets of Bi). We define the Hitting Set Problem as follows. We are given a set A = {a1, . . . , an}, a collection B1, B2, . . . , Bm of subsets of A, and an non-negative integer k. We are asked: is there a hitting set H ⊆ A for B1, B2, . . . , Bm so that the size of H is at most k? Prove that the Hitting Set problem is NP-complete
Answer:
Explanation:
This is actually quite straight forward to solve, first lets be mindful of the explanation so with this basis we can tackle future problems.
The solution may very well may be appeared in the accompanying manner:
This solution needs to display that the set H-one can without much of a stretch confirm in polynomial-time if H is of size k and meets every one of the sets B1.....Bm .
We lessen from Vertex Cover.Consider an example of the Vertex-Cover issue chart G=(V,E) and a positive whole number k.We map it to an occurrence of the hitting set issue as follows.The set An is of vertices V.
Also we know that For each edge e has a place with E we have a set Se Consisting of two end-purposes of e.It is anything but difficult to see that a lot of vertices S is a vertex front of G iff the relating components from a hitting set in the hitting set case.
Following are the illustration to the given question:
The solution must demonstrate that only if H is of size k and overlaps each one of the sets B1.....Bm, can one simply verify it in time complexity.You start with Vertex Cover and decrease from there.Considering the Vertex-Cover issue graph G = (V, E) with a positive integer k as an example.As shown below, we map this to a hitting set issue case V are the vertices of set A.It has the set Se that includes 2 end-points of e for each edge of e belonging to E.A vertex set "S" covers vertex "G" if the matching members from a hitting set were present in the striking setting instance.Learn more set:

Answer:
Here is the C++ program:
#include <fstream> //to create, write and read a file
#include <iostream> // to use input output functions
using namespace std; //to access objects like cin cout
const int MAXNAME = 20; //MAXNAME is set to 20 as a constant
int main(){ //start of main() function
ifstream inData; //creates an object of ifstream class
inData.open("grades.txt"); //uses that object to access and opens the text file using open() method
char name[MAXNAME + 1]; // holds the names
float average; //stores the average
inData.get(name,MAXNAME+1); //Extracts names characters from the file and stores them as a c-string until MAXNAME+1 characters have been extracted
while (inData){ //iterates through the file
inData >> average; //reads averages from file using the stream extraction operator
cout << name << " has a(n) " << average << " average." << endl; //prints the names along with their averages
inData.ignore(50,'\n'); //ignores 50 characters and resumes when new line character is reached. It is used to clear characters from input buffer
inData.get(name,MAXNAME+1);} //keeps extracting names from file
return 0; }

Define a method printAll() for class PetData that prints output as follows with inputs "Fluffy", 5, and 4444. Hint: Make use of the base class' printAll() method.
Name: Fluffy, Age: 5, ID: 4444
// ===== Code from file AnimalData.java =====
public class AnimalData {
private int ageYears;
private String fullName;
public void setName(String givenName) {
fullName = givenName;
}
public void setAge(int numYears) {
ageYears = numYears;
}
// Other parts omitted
public void printAll() {
System.out.print("Name: " + fullName);
System.out.print(", Age: " + ageYears);
}
}
// ===== end =====
// ===== Code from file PetData.java =====
public class PetData extends AnimalData {
private int idNum;
public void setID(int petID) {
idNum = petID;
}
// FIXME: Add printAll() member function
/* Your solution goes here */
}
// ===== end =====
// ===== Code from file BasicDerivedOverride.java =====
import java.util.Scanner;
public class BasicDerivedOverride {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
PetData userPet = new PetData();
String userName;
int userAge;
int userID;
userName = scnr.next();
userAge = scnr.nextInt();
userID = scnr.nextInt();
userPet.setName(userName);
userPet.setAge (userAge);
userPet.setID (userID);
userPet.printAll();
System.out.println("");
}
}
// ===== end =====
Answer:
public void printAll(){ // member function petAll()
super.printAll(); // calls printAll() method of the superclass (base class) AnimalData using super keyword
System.out.print(", ID: " + idNum);} // prints the ID stored in the idNum data member of the PetData class
Explanation:
Here is the complete PetData class:
public class PetData extends AnimalData { //
private int idNum;
public void setID(int petID) {
idNum = petID; }
// FIXME: Add printAll() member function
/* Your solution goes here */
public void printAll(){
super.printAll();
System.out.print(", ID: " + idNum);} }
PetData class is a subclass which is inherited from the base class AnimalData.
This class has a private data member which is the variable idNum which is used to store the ID value.
It has a member function setID with parameter petID which is the idNum. This method basically acts as a mutator and sets the user ID.
This class has another method printAll() that uses super keyword to access the method printAll() of the base class which is AnimalData
super basically refers to the base class objects.
Here the super keyword is used with the method name of subclass PetData in order to eliminate the confusion between the method printAll() of AnimalData and PetData since both have the same method name.
In the main() method the use is prompted to enter values for userName, UserAge and UserID. Lets say user enters Fluffy as user name, 5 as user age and 4444 as userID. Then the statement userPet.printAll(); calls printAll() method of PetData class as userPet is the object of PetData class.
When this method is called, this method calls printAll() of AnimalData class which prints the Name and Age and printAll() of PetData class prints the ID. Hence the program gives the following output:
Name: Fluffy, Age: 5, ID: 4444
The program illustrates the use of methods.
Methods are used to group related codes together, so that they function as one, after being called/invoked
The printAll() method, where comments are used to explain each line is as follows:
//This defines the printAll() method
public void printAll(){
//This calls the base class of the printAll() method
super.printAll();
//This prints the required output
System.out.print(idNum);

Confidentiality, integrity, and availability (C-I-A) are large components of access control. Integrity is __________. ensuring that a system is accessible when needed defining risk associated with a subject accessing an object ensuring that a system is not changed by a subject that is not authorized to do so ensuring that the right information is seen only by subjects that are authorized to see it
Answer: ensuring that a system is not changed by a subject that is not authorized to do so
Explanation: Access control refers to pribcues which are employed in the bid thlo ensure the security of data and information. It provides the ability to authenticate and authorize access to information and data thereby preventing unwarranted access and tampering of the information. Integrity in terms of data security and access control is is concerned with modification to an existing or original data by unauthorized sources. When unauthorized addition or subtraction occurs on a data, the integrity of such data has been compromised. Therefore, authorization is required whenever a source is about to access certain information whereby only those with the right authorization code will be allowed, Inputting an incorrect pass code after a certain number of tries may result in system lock down as access control detects a a possible intrusion
John is analyzing an attack against his company in which the attacker found comments embedded in HTML code that provided the clues needed to exploit a software vulnerability. Using the STRIDE model, what type of attack did he uncover?
Answer:
Information Disclosure
Explanation:
Hello, the fact that the attacker was able to gather information from within the embedded HTML code suggests that the original developer did not properly store information, revealing potential issues or vulnerabilities in his/her design.
The STRIDE model stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.
Using the STRIDE model, one would say this would be a simple information disclosure attack, since the attacker used retrieved information to breach the system.

Compute their Cartesian product, AxB of two lists. Each list has no more than 10 numbers.
For example, given the two input lists:
A = [1,2]
B = [3,4]
then the Cartesian product output should be:
AxB = [(1,3),(1,4),(2,3),(2,4)]
Answer:
The program written in Python is as follows: (See Attachments for source file and output)
def cartesian(AB):
if not AB:
yield ()
else:
for newlist in AB[0]:
for product in cartesian(AB[1:]):
yield (newlist,)+product
A = []
B = []
alist = int(input("Number of items in list A (10 max): "))
while(alist>10):
alist = int(input("Number of items in list A (10 max): "))
blist = int(input("Number of items in list B (10 max): "))
while(blist>10):
blist = int(input("Number of items in list B (10 max): "))
print("Input for List A")
for i in range(alist):
userinput = int(input(": "))
A.append(userinput)
print("Input for List B")
for i in range(blist):
userinput = int(input(": "))
B.append(userinput)
print(list(cartesian([A,B])))
Explanation:
The function to print the Cartesian product is defined here
def cartesian(AB):
This following if condition returns the function while without destroying lists A and B
if not AB:
yield ()
If otherwise
else:
The following iteration generates and prints the Cartesian products
for newlist in AB[0]:
for product in cartesian(AB[1:]):
yield (newlist,)+product
The main method starts here
The next two lines creates two empty lists A and B
A = []
B = []
The next line prompts user for length of list A
alist = int(input("Number of items in list A (10 max): "))
The following iteration ensures that length of list A is no more than 10
while(alist>10):
alist = int(input("Number of items in list A (10 max): "))
The next line prompts user for length of list B
blist = int(input("Number of items in list B (10 max): "))
The following iteration ensures that length of list B is no more than 10
while(blist>10):
blist = int(input("Number of items in list B (10 max): "))
The next 4 lines prompts user for input and gets the input for List A
print("Input for List A")
for i in range(alist):
userinput = int(input(": "))
A.append(userinput)
The next 4 lines prompts user for input and gets the input for List B
print("Input for List B")
for i in range(blist):
userinput = int(input(": "))
B.append(userinput)
This line calls the function to print the Cartesian product
