4.17 LAB: Data File A comma separated value (.csv) file has been included to be used for this program. Each line contains two values, a name and a number separated by a comma (except the first line, which contains the titles for the value types). The name is that of a writer and the number refers to the number of works the writer has written. Ex. Jane Austen,6. Each line is an entry and each entry number can be updated by identifying the associated name. Once complete, the following program opens data file allWorks.csv and asks if the user wants to update entries or add new entries. All entries are stored in an array while being read in and updated. The program then writes the array to the file, overwriting the original contents. The following TODO sections must be completed. Open allWorks.csv for reading/input. Locate an entry to be updated by name (use the Java String indexOf() method) Add a new entry if the name isn't found in the file (give the entry a new number) Open file allWorks.csv for output Write contents of the array to allWorks.csv (original file is overwritten)
Answer:
import csv
def Csvreader(filename):
with open("filename", "r") as file:
content = file.csv_reader()
list_content = list(content)
file.close
return list_content
Explanation:
This is a python description of the function that reads the csv file and converts it to a list, from the list, each item can accessed with its index and updated directly. Use this to draw the same conclusion for a java program.
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);
}

Type in the above program as swap.cpp. Add a comment to include your name and date. Compile and run with different values.2. To find out why this is not working, add the following output statements to the swap function.a. cout << " beginning of swap" << x << " " << y << endl;b. cout << " end of swap" << x << " " << y << endl;Are the variables being swapped inside the swap function?3. Explain why this program is not working correctly.4. Fix the program so the swap will work. Compile and run and be sure the swap works.5. Submit a copy of the final listing and output. Also include a copy of the hierarchy chart for the program.
Answer:
Fix:
void Swap(int &x, int &y){
int temp;
temp = x;
x = y;
y = temp; }
See the explanation
Explanation:
1. swap.cpp
//Name: ABC Date: dd/mm/yyyy
#include
using namespace std;
void Swap(int x,int y); //prototype
int main(){
int num1, num2;
cout << "Please enter two numbers to swap, the same numbers will quit." << endl;
cin >> num1 >> num2;
while (num1 != num2) {
Swap(num1,num2);
cout << "After swap, the numbers are " << num1 << " " << num2 << endl;
cout << "Please enter two numbers to swap, ";
cout << "the same numbers will quit." << endl;
cin >> num1 >> num2; }
cout << "Thanks!" << endl;
return 0; }
//********************//This subroutine swaps two numbers // ********************
void Swap(int x, int y){
int temp;
temp = x;
x = y;
y = temp;}
The output of this program with num1 = 1 and num2 = 2 is:
Please enter two numbers to swap, the same numbers will quit. 1 2 After swap, the numbers are 1 2 Please enter two numbers to swap, the same numbers will quit. 1
1 Thanks!
Notice that the numbers 1 and 2 are not swapped correctly even when the Swap() method is called in the main() function.
The other numbers 1 and 1 are entered in order to quit the program.
2.
In this part first output statement a) is added to the start of Swap() method before swapping the numbers x and y and the output statement b) is added to the last after the set of operations performed to swap x and y.
void Swap(int x, int y){
cout << " beginning of swap " << x << " " << y << endl;
int temp;
temp = x;
x = y;
y = temp;
cout << " end of swap " << x << " " << y << endl; }
Lets say x = 1 and y = 2
The output of these two statements is:
beginning of swap 1 2
end of swap 2 1
This shows that the Swap() function is working correctly and swapping the two numbers x and y.
3.
The reason that the program is not working properly is that x and y are value parameters. They are like local variables and local to the Swap() function. So changes made to them have no effect on the calling functions arguments num1 and num2. That is why the result remains the same when this function is called in the main().
In these three statements of Swap() method:
int temp = x;
x = y;
y = temp;
temp is a local variable which is local to this Swap function
Similarly x=y; and y= temp statements make changes only in the local copy and not in the values of num1 and num2 which are passed to this function in main()
So for the above example where num1 = 1 and num2 = 2, the statement
cout << "After swap, the numbers are " << num1 << " " << num2 << endl;
displays:
After swap, the numbers are 1 2
This means their real values are printed as it is without swapping the values.
4.
The solution is to mark the parameters x and y of the function Swap() as reference parameters in the following way:
void Swap(int &x, int &y)
In this way the memory address of each argument num1 and num2 is passed to the Swap(). The Swap() uses this address to both access and change the values.
So Swap(num1,num2); function call passes the memory address the actual parameters.
For the reference parameter an ampersand (&) is used before the variables x and y of Swap method. Now any changed made to these variables will effect the calling function arguments num1 and num2. So if x and y are swapped then num1 and num2 are also swapped when this function is called in main().
So change the prototype of Swap function as:
void Swap(int &x,int &y);
Change the function definition as:
void Swap(int &x, int &y){
int temp;
temp = x;
x = y;
y = temp; }
Now the program gives the following output:
Please enter two numbers to swap, the same numbers will quit. 1 2 After swap, the numbers are 2 1 Please enter two numbers to swap, the same numbers will quit. 1 1 Thanks!
See now the numbers are correctly swapped. The program and its output is attached.
Define a function pyramid_volume with parameters base_length, base_width, and pyramid_height, that returns the volume of a pyramid with a rectangular base. Sample output with inputs: 4.5 2.1 3.0
Answer:
def pyramid_volume(base_length, base_width, pyramid_height):
base_area = base_length * base_width
volume = 1 / 3 * base_area * pyramid_height
return volume
Explanation:
Create a function called pyramid_volume that takes base_length, base_width, pyramid_height as parameters
The formula to calculate the volume of a pyramid is = 1/3Ah, A is the base area, h is the height
Inside the function, calculate the base area, multiply base_length with base_width. Then, calculate the volume using the formula. Return the volume
Arrays save space because all elements of an array are stored in a single memory location while a list of variables needs a separate location for each variable.
a. True
b. False
Answer:
Option A. True Is the correct answer
Explanation:
Arrays are allowed to store multiple elements of the same data type, all of them stored with the same array hence preventing the need for creating separate variables for each element. An array therefore will act as a container for storing several variables all of the same type. This offers a lot of convinience and enhances better memory space management. In java arrays are declared by:
dataType[] arrayName;
Where dataType is the datatype of elements to be stored in the arrays. This is followed by a pair of square brackets then the name of the array.
for declaration and initialization in Java, the new keyword is used as:
dataType[] arrayName = new dataType[arraySize];

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.

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.
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:

Which methods are commonly used by sysadmins to organize issues?
a. Random machine checks
b. Daily checks on each machine
c. Service monitoring alerts
Answer:
c. Service monitoring alerts
Explanation:
Given the fact that system administrators manage so many computer systems, they are equipped with service monitoring alerts that indicate when there is a problem with any of the systems and the extent or magnanimity of the problem. This is necessary so as to attract responses from the right personnel.
Metrics are deployed to gather raw data on the system's use and behavior. Monitoring compiles these data to useful information that can be stored when they meet up to some standards. The alert system sends out signals to the administrators when some acceptable standards are not met. So, the service, monitoring alerts are used by system admins to organize issues.

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

Fill in the code in bold so that the data is properly read from grades.txt. and the desired output to the screen is as follows: OUTPUT TO SCREEN DATAFILE Adara Starr has a(n) 94 average Adara Starr 94 David Starr has a(n) 91 average David Starr 91 Sophia Starr has a(n) 94 average Sophia Starr 94 Maria Starr has a(n) 91 average Maria Starr 91 Danielle DeFino has a(n) 94 average Danielle DeFino 94 Dominic DeFino has a(n) 98 average Dominic DeFino 98 McKenna DeFino has a(n) 92 average McKenna DeFino 92 Taylor McIntire has a(n) 99 average Taylor McIntire 99 Torrie McIntire has a(n) 91 average Torrie McIntire 91 Emily Garrett has a(n) 97 average Emily Garrett 97 Lauren Garrett has a(n) 92 average Lauren Garrett 92 Marlene Starr has a(n) 83 average Marlene Starr 83 Donald DeFino has a(n) 73 average Donald DeFino 73
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.
