Suppose that you write a subclass of Insect named Ant. You add a new method named doSomething to the Ant class. You write a client class that instantiates an Ant object and invokes the doSomething method. Which of the following Ant declarations willnot permit this? (2 points)I. Insect a = new Ant ();II. Ant a = new Ant ();III. Ant a = new Insect ();1) I only2) II only3) III only4) I and II only5) I and III only
Answers
Answer:
5) I and III only
Explanation:
From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.

c. DTE and DCE describes the interface and direction of data flow between devices; a single device may have both types of interfaces.
Explanation:
DTE stands for Data Terminal Equipment. It is a device that initiates or controls a device's serial connection. The term DCE stands for Data Communications Equipment. It is a device that is used to a modem or other communication interfaces to the DTE device. DTE is a communication receptor, while DCE is a communication broadcaster or distributor.
3. Circular, array-backed queue In the following class, which you are to complete, the backing array will be created and populated with Nones in the __init__ method, and the head and tail indexes set to sentinel values (you shouldn't need to modify __init__). Enqueuing and Dequeuing items will take place at the tail and head, with tail and head tracking the position of the most recently enqueued item and that of the next item to dequeue, respectively. To simplify testing, your implementation should make sure that when dequeuing an item its slot in the array is reset to None, and when the queue is emptied its head and tail attributes should be set to -1.

Answer and Explanation:
A spreadsheet is an interactive computer application for the analysis and storage of data. The database is a collection of data and accessed from the computer system. This is the main difference between spreadsheets and databases. The spreadsheet is accessed by the user and the database is accessed by the user. The database can store more data than a spreadsheet. The spreadsheet is used for tasks and used in enterprises to store the data. Spreadsheet and database are two methods and the main difference is the computer application that helps to arrange, manage and calculate the data. The database is a collection of data and organized to access easily. Spreadsheet applications were the first spreadsheet on the mainframe. Database stores and manipulates the data easily. The database maintains the data and stores the records of teachers and courses. The spreadsheet is the computer application and analyzing the data in table form.

The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.
Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.

Pokemon *ptr;
ptr = new Pokemon[6];
Answer:
delete ptr;
Explanation:
The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.
The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).

d. L(x, y), (L(y, x) ^ L(A, B))
Answers
Answer:
Unification may be a process by which two logical individual atomic expressions, identical by replacing with a correct substitution. within the unification process, two literals are taken as input and made identical using the substitution process. There are some rules of substitution that has got to be kept in mind:
The predicate symbol must be an equivalent for substitution to require place.
The number of arguments that are present in both expressions must be equivalent.
Two similar variables can't be present within the same expression
Explanation:
a. American (Bob), American (y):-
In this scenario, Unification is feasible consistent with the principle. The substitution list is going to be [y/Bob].
b. Enemy (Nono, America), Enemy(x,y):-
In this scenario, the Unification is feasible consistent with the principles. The substitution list is going to be [x/Nono, y/America].
c. Weapon (Missile), soldTo (Missile, y), Weapon (x), soldTo (x, Nono):-
In this scenario, the Unification isn't possible because the predicate is different i.e. Weapon and soldTo.
d. L(x, y), (L(y, x) ^ L(A, B)):-
In this scenario, Unification isn't possible because the number of arguments is different within the given expression

Write a java program that reads a list of integers and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is:
5 2 4 6 8 10
the output is:
10,8,6,4,2,
To achieve the above, first read the integers into an array. Then output the array in reverse.
Answers
Answer:
Explanation:
using namespace std;
#include <iostream>
int Go()
{
int N;
int A[20];
cout << " How many integers do you have ??? :>";
cin >> N;
if (N>20) { N=20; }
for (int iLoop=0; iLoop<N; iLoop++)
{
cout << "Input integer # " << (iLoop+1) << " :>";
cin >> A[iLoop];

A Java program that reads a list of integers and outputs them in reverse is written as,
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end

}
Given that,
Write a Java program that reads a list of integers and outputs those integers in reverse.
Here, The input begins with an integer indicating the number of integers that follow.
For coding simplicity, follow each output integer by a comma, including the last one.
So, A Java program that reads a list of integers and outputs them in reverse:
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer

Operating Platform:-
In terms of platforms, there are differences between, mobile games and pc games within the way it's used, the operator, the most event play, the sport design, and even the way the sport work. we all know that each one the games on console platforms, PC and mobile, have their own characteristic which has advantages and disadvantages All platforms compete to win the rating for the sake of their platform continuity.
Operating system architectures:-
Arm: not powerful compared to x86 has many limitations maximum possibility on arm arch is mobile gaming.
X86: very powerful, huge development so easy to develop games on platforms like unity and unreal, huge hardware compatibility and support
Storage management:-
On the storage side, we've few choices where HDD is slow and too old even a replacement console using SSD. so SSD is the suggested choice. But wait SSD have also many options like SATA and nvme.
Memory management:-
As recommended windows, Each process on 32-bit Microsoft Windows has its own virtual address space that permits addressing up to 4 gigabytes of memory. Each process on 64-bit Windows features a virtual address space of 8 terabytes. All threads of a process can access its virtual address space. However, threads cannot access memory that belongs to a different process.
Distributed systems and networks:-
Network-based multi-user interaction systems like network games typically include a database shared among the players that are physically distributed and interact with each other over the network. Currently, network game developers need to implement the shared database and inter-player communications from scratch.
Security:-
As security side every game, there's an excellent risk that, within the heat of the instant, data are going to be transmitted that you simply better keep to yourself. There are many threats to your IT.
Define on the whole data protection matters when developing games software may cause significant competitive advantages. Data controllers are obliged under the GDPR to attenuate data collection and processing, using, as an example , anonymization or pseudonymization of private data where feasible.

The manager of the Super Supermarket would like to be able to compute the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weight in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables: ItemName Pounds Ounces PoundPrice TotalPrice UnitPriceYou will need the following formulas: UnitPrice = PoundPrice/16 TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answers
Answer:
The program in Python is as follows:
name = input("Name of item: ")
PoundPrice = int(input("Pound Price: "))
Pounds = int(input("Weight (pounds): "))
Ounces = int(input("Weight (ounce): "))
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
print("Unit Price:",UnitPrice)
print("Total Price:",TotalPrice)
Explanation:
This gets the name of the item
name = input("Name of item: ")
This gets the pound price
PoundPrice = int(input("Pound Price: "))
This gets the weight in pounds
Pounds = int(input("Weight (pounds): "))
This gets the weight in ounces
Ounces = int(input("Weight (ounce): "))
This calculates the unit price
UnitPrice = PoundPrice/16
This calculates the total price
TotalPrice = PoundPrice * (Pounds + Ounces/16)
This prints the unit price
print("Unit Price:",UnitPrice)
This prints the total price
print("Total Price:",TotalPrice)

This ultimately implies that, search engine optimization (SEO) helps individuals and business firms to maximize the amount of traffic generated by their website i.e strategically placing their website at the top of the results returned by a search engine through the use of algorithms, keywords and phrases, hierarchy, website updates etc.
Hence, search engine optimization (SEO) is focused on improving the ranking in user searches by simply increasing the probability (chances) of a specific website emerging at the top of a web search.
Typically, this is achieved through the proper use of descriptive page titles and heading tags with appropriate keywords.
Generally, the conversion rate is mainly designed to be the highest for keyword searches classified as buyers because they're the main source of revenue for a business and by extension profits.
