Answer:
Explanation:
/* From the information provided, For now will consider the name of table as TRIPGUIDES*/
/*In all the answers below, the syntax is based on Oracle SQL. In case of usage of other database queries, answer may vary to some extent*/
1.
Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name
/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/
2.
Select R.Reservation_ID, R.Trip_ID , R.NUM_PERSONS from Reservation R, Customer C where C.Customer_Num=R.Customer_Num and C.LAST_NAME='Goff' and C.FIRST_NAME='Ryan'
/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field
*/
3.
Select T.TRIP_NAME from TRIP T,GUIDE G,TRIPGUIDES TG where T.TRIP_ID=TG.TRIP_ID and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Abrams' and G.FIRST_NAME='Miles'
/*
Here,we choose three tables TRIP,GUIDE and TRIPGUIDES. Here we selected those trips where we have guides as Miles Abrms in the GUIDES table and equated Trip_id from TRIPGUIDES to TRIP.TRIP_Name so that can have the desired results
*/
4.
Select T.TRIP_NAME
from TRIP T,TRIPGUIDES TG ,G.GUIDE
where T.TRIP_ID=TG.TRIP_ID and T.TYPE='Biking' and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Boyers' and G.FIRST_NAME='Rita'
/*
In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.
*/
5.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='2016-07-23' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
/*
The explaination for this one will be equivalent to the previous question where we just equated the desired columns where we equiated the desired columns in respective fields and also equated the common entities like trip ids and customer ids so that can join tables properly
*/
/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the
dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='7/23/2016' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
*/
6.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION R WHERE R.TRIP_ID IN
{SELECT TRIP_ID FROM TRIP T WHERE STATE='ME'}
/*
In the above question, we firstly extracted all the trip id's which are having locations as maine. Now we have the list of all the trip_id's that have location maine. Now we just need to extract the reservation ids for the same which can be trivally done by simply using the in clause stating print all the tuples whose id's are there in the list of inner query. Remember, IN always checks in the set of values.
*/
7.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION WHERE
EXISTS {SELECT TRIP_ID FROM TRIP T WHERE STATE='ME' and R.TRIP_ID=T.TRIP_ID}
/*
Unlike IN, Exist returns either true or false based on existance of any tuple in the condition provided. In the question above, firstly we checked for the possibilities if there is a trip in state ME and TRIP_IDs are common. Then we selected reservation ID, trip ID and Trip dates for all queries that returns true for inner query
*/
8.
SELECT G.LAST_NAME,G.FIRST_NAME FROM GUIDE WHERE G.GUIDE_NUM IN
{
SELECT DISTINCT TG.GUIDE_NUM FROM TRIPGUIDES TG WHERE TG.TRIPID IN {
SELECT T.TRIP_ID FROM TRIP T WHERE T.TYPE='Paddling'
}
}
/*
We have used here double nested IN queries. Firstly we selected all the trips which had paddling type (from the inner most queries). Using the same, we get the list of guides,(basically got the list of guide_numbers) of all the guides eds which were on trips with trip id we got from the inner most queries. Now that we have all the guide_Nums that were on trip with type paddling, we can simply use the query select last name and first name of all the guides which are having guide nums in the list returned by middle query.

Fill in multiple blanks for [x], [y], [z]. Consider a given TCP connection between host A and host B. Host B has received all from A all bytes up to and including byte number 2000. Suppose host A then sends three segments to host B back-to-back. The first, second and third segments contain 50, 600 and 100 bytes of user data respectively. In the first segment, the sequence number is 2001, the source port number is 80, and the destination port number is 12000. If the first segment, then third segment, then second segment arrive at host B in that order, consider the acknowledgment sent by B in response to receiving the third segment. What is the acknowledgement number [x], source port number [y] and destination port number [z] of that acknowledgement
In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
Complete the implementation of the following methods:__init__hasNext()next()getFirstToken()getNextToken()nextChar()skipWhiteSpace()getInteger()
From method names, I am compelled to believe you are creating some sort of a Lexer object. Generally you implement Lexer with stratified design. First consumption of characters, then tokens (made out of characters), then optionally constructs made out of tokens.
Hope this helps.
Register the countChars event handler to handle the keydown event for the textarea tag. Note: The function counts the number of characters in the textarea.
Do not enter anything in the HTML file, put your code in the JavaScript section where it says "Your solution goes here"
1 klabel for-"userName">user name: 2
3
Answer:
Explanation:
The following Javascript code is added in the Javascript section where it says "Your solution goes here" and counts the current number of characters in the text within the textArea tag. A preview can be seen in the attached image below. The code grabs the pre-created variable textareaElement and attached the onkeypress event to it. Once a key is pressed it saves the number of characters in a variable and then returns it to the user.
var textareaElement = document.getElementById("userName");
function textChanged(event) {
document.getElementById("stringLength").innerHTML = event.target.value.length;
}
// Your solution goes here
textareaElement.onkeypress = function() {
let numOfCharacters = textareaElement.value.length;
return numOfCharacters;
};
Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.
Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}

Suppose that a queue is implemented using a circular array of size 12. What is the value of last after the following operations?
10 enqueue operations
5 dequeue operations
6 enqueue operations
10 dequeue operations
8 enqueue operations
2 dequeue operations
3 enqueue operations
Last = 10
Answer:
10
Explanation:
An enqueue operation is a function that adds an element(value) to a queue array. A dequeue operations removes an element from a queue array. Queue arrays follow a first-in-first-out approach, so elements that are first stored in the queue are removed/accessed first(enqueue operations add elements at the rear of the queue array).
The following operations leave 10 elements in the queue of array size 12 after its done:
10 enqueue operations= adds 10 elements
5 dequeue operations= removes 5 elements( 5 elements left in queue)
6 enqueue operations= adds 6 elements(11 elements in queue)
10 dequeue operations= removes 10 elements(1 element left in queue)
8 enqueue operations= adds 8 elements(9 elements in queue)
2 dequeue operations= removes 2 elements(7 elements left in queue)
3 enqueue operations= adds 3 elements(10 elements in queue)
Therefore there are 10 elements in the queue after enqueue and dequeue operations.

Assign courseStudent's name with Smith, age with 20, and ID with 9999. Use the print member function and a separate cout statement to output courseStudents's data. End with a newline. Sample output from the given program:
#include
#include
using namespace std;
class PersonData {
public:
void SetName(string userName) {
lastName = userName;
};
void SetAge(int numYears) {
ageYears = numYears;
};
// Other parts omitted
void PrintAll() {
cout << "Name: " << lastName;
cout << ", Age: " << ageYears;
};
private:
int ageYears;
string lastName;
};
class StudentData: public PersonData {
public:
void SetID(int studentId) {
idNum = studentId;
};
int GetID() {
return idNum;
};
private:
int idNum;
};
int main() {
StudentData courseStudent;
/* Your solution goes here */
return 0;
}
Answer:
Replace /* Your solution goes here */
with the following:
courseStudent.SetName("Smith");
courseStudent.SetAge(20);
courseStudent.SetID(9999);
courseStudent.PrintAll();
cout <<courseStudent.GetID();
Explanation:
From the given code segment, we have the following methods defined under the StudentData class;
SetName -> It receives name from the main
SetAge -> It receives age from the main
SetID --> It receives ID from the main and passes it to GetID method
printID --> Prints all the required output.
So, we have:
Pass name to setName
courseStudent.SetName("Smith");
Pass age to setAge
courseStudent.SetAge(20);
Pass ID to setID
courseStudent.SetID(9999);
Print all necessary outputs
courseStudent.PrintAll();
Manually print the student ID
cout <<courseStudent.GetID();
A security administrator currently spends a large amount of time on common security tasks, such aa report generation, phishing investigations, and user provisioning and deprovisioning This prevents the administrator from spending time on other security projects.

Analyze the following code:
// Enter an integer Scanner input = new Scanner(System.in);
int number = input.nextInt(); if (number <= 0) System.out.println(number);
1) The if statement is wrong, because it does not have the else clause;
2) System.out.println(number); must be placed inside braces;
3) If number is zero, number is displayed;
4) If number is positive, number is displayed.
5) number entered from the input cannot be negative.
Answer:
3) If number is zero, number is displayed;
Explanation:
The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement. Therefore, the only statement in the question that is actually true would be ...
3) If number is zero, number is displayed;
Answer:
If number is zero, number is displayed
Explanation:
Given
The above code segment
Required
What is true about the code segment
Analyzing the options, we have:
(1) Wrong statement because there is no else clause
The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program
Hence, (1) is false
(2) The print statement must be in { }
There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.
Hence, (2) is false
(3) number is displayed, if input is 0
In the analysis of the program, we have: number <=0
i.e. the if statement is true for only inputs less than 0 or 0.
Hence, number will be printed and (3) is false
(4) number is displayed for positive inputs
The valid inputs have been explained in (3) above;
Hence, (4) is false.
(5) is also false

what is the process by which we can control what parts of a program can acccess the members of class
Answer:
Encapsulation.
Explanation:
Information hiding involves using private fields within classes and it's a feature found in all object-oriented languages such as Java, Python, C#, Ruby etc.
In object-oriented programming language, a process known as encapsulation is used for the restrictions of the internal data of a software program from the outside code, therefore preventing an unauthorized direct access to the codes. This is achieved through the use of classes.
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.
A _____ is a systematic and methodical evaluation of the exposure of assets to attackers, forces of nature, or any other entity that is a potential harm.
Answer:
Vulnerability assessment
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
