When an object reference is passed as a parameter to a method, modifying the members of that object from inside the method will result in a change to that object as seen from the client.
a. True
b. False
Answer:
A) True
Explanation:
Objects are known as reference types, meaning that they are always accessed by references, not copied. When a method is called, passing an object to it, Java passes a reference of that object to the method and when that reference is modified, the changes can be seen in the object itself. Therefore a mutable object can be mutated anywhere- either from where it is created or by a method it is passed to. Hence the need to always use privacy modifier keywords such as public, private or protected, to determine the exposure of class properties and methods.

As Assembly language code runs on a CPU invoking functions and using the stack, it is clear that CPU registers are
Answer:
shared resources.
Explanation:
Assembly language is a low-level language that is used commonly in programming operating systems in large systems or in single task algorithms in embedded systems.
Its files are compiled in a CPU, using available resources like registers, buses, etc. All the content of the assembly program are read and compiled before execution.
The functions and statements invoked in the program shares the resources by duplicating the content of the registers in variables.
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
print(list(cartesian([A,B])))

Write a function called count_occurrences that takes two strings. The second string should only be one character long. The function should return how many times the second string occurs in the first string.
Answer:
Here is the Python function:
def count_occurrences (string1 , string2): # method that takes two strings as parameter and returns how many times second string occurs in first
count = 0 #counts number of occurrence of string2 in string1
for word in string1: #iterates through each word of the string1
for character in word: #iterates through each character of each word in string1
if character == string2: # checks if the character in string1 is equal to the character of string2
count = count + 1 #adds 1 to the count of string2 in string1
return count #returns number of times the string2 occurs in string1
#in order to check the working of the function add the following lines to the code:
first_str = input("Enter the first string: ") #prompts user to enter first string
second_str = input("Enter the second string (one character long): ") #prompts user to enter second string which should be one character long
occurrence = count_occurrences(first_str,second_str) #calls count_occurrences method by passing both strings to it
print(second_str,"occurs",occurrence,"times in",first_str) #prints how many times the second_str occurs in the first_str on output screen
Explanation:
The program is well explained in the comments added to each statement of the above code. I will explain the program with an example:
Suppose
string1 = "hello world"
string2 = 'l'
So the method count_occurrences() should return how many times l occurs in hello world.
count is used to count the number of occurrences of l in hello world. It is initialized to 0.
The first loop iterates through each word of string1. The first word of string1 is "hello"
The second loop iterates through each character/letter of each word. So the first letter of "hello" word is 'h'.
The if condition if character == string2: checks if the character is equal to string2 i.e. l.
character = "h"
string2 = "l"
The are not equal so the program moves to the next character of word hello which is e. The if condition again evaluates to false because e is not equal to l. So the program moves to the next character of word hello which is l.
This time the if condition evaluates to true because
character = "l"
string2 = "l"
character == string2
l == l
So the if part is executed which has the following statement:
count = count + 1
So the count is added to 1. count was 0 previously. Now
count = 1
Next the program moves to the next character of word hello which is l. This time the if condition evaluates to true because the character l matches with string2. So count is again incremented to 1. count = 2.
Next the program moves to the next character of word hello which is o. The if condition evaluates to false as o does not match with string2 i.e. l. So the count remains 2.
Next the first loop moves to the next word of the string1 = "world". The inner (second) for loop iterates through each character of "world" from "w" to "d" and checks if any character is equal to string2. Only one character is equal to string2 in "world". So count is incremented to 1. Hence count = 3
After the loop ends the statement return count returns the number of times string2 occurs in the string1. So the output is:
l occurs 3 times in hello world
Answer:
def count_occurrences(sentence, thing_to_count):
times = 0
for word in sentence:
for letter in word:
if letter == thing_to_count: times += 1
return times

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

A "responsive design" for mobile applications is a design that responds to a user's: A. digital device and screen size. B. needs. C. location. D. voice commands. E. gestures .
Answer:
A. digital device and screen size.
Explanation:
A "responsive design" for mobile applications is a design that responds to a user's digital device and screen size.
In Computer programming, a responsive web design makes it possible for various websites to change layouts in accordance with the user's digital device and screen size.
Hence, an end user's behavior and environment influences the outcome of their content and layout in a responsive design for mobile applications and websites.
This ultimately implies that, a responsive design is a strategic approach which enables websites to display or render properly with respect to the digital device and screen size of the user.
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:

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.

Write a statement to create a Google Guava Multimap instance which contains student ids as keys and the associated values are student profiles.
Answer: provided in the explanation section
Explanation:
Note: take note for indentation so as to prevent error.
So we import com.google.common.collect.Multimap;
import java.util.Collection;
import java.util.Map;
class Main {
public static void main(String[] args) {
// key as studentId and List of Profile as value.
Multimap<String,Profile> multimap = ArrayListMultimap.create();
multimap.put("id1", new ExamProfile("examStudentId1"));
multimap.put("id1", new ELearningProfile("userId1"));
multimap.put("id2", new ExamProfile("examStudentId2"));
multimap.put("id2", new ELearningProfile("userId2"));
// print the data now.
for (Map.Entry<String, Collection<Profile>> entry : multimap.entrySet()) {
String key = entry.getKey();
Collection<String> value = multimap.get(key);
System.out.println(key + ":" + value);
}
}
}
// assuming String as the studentId.
// assuming Profile as the interface. And Profile can multiple implementations that would be
// specific to student.
interface Profile {
}
class ExamProfile implements Profile {
private String examStudentId;
public ExamProfile(String examStudentId) {
this.examStudentId = examStudentId;
}
}
class ELearningProfile implements Profile {
private String userId;
public ELearningProfile(String userId) {
this.userId = userId;
}
}
This code is able to iterate through all entries in the Google Guava multimap and display all the students name in the associated students profile.

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; }
Explanation:
The program is well explained in the comments added to each line of the code. The program uses fstream object inData to access the grades.txt file. It gets and extracts the contents of the file using get() method, reads and extracts averages from file using the stream extraction operator. Then program displays the names along with their averages from grades.txt on output screen.
The grades.txt file, program and its output is attached.
