(Geometry: area of a triangle)
Write a C++ program that prompts the user to enter three points (x1, y1), (x2, y2), (x3, y3) of a triangle and displays its area.
The formula for computing the area of a triangle is:
s = (side1 + side2 + side3) / 2
area = square root of s(s - side1)(s - side2)(s - side3)

Sample Run:
Enter three points for a triangle: 1.5 -3.4 4.6 5 9.5 -3.4
The area of the triangle is 33.6

The following statements are true about cyberbullying: Cyberbullying uses electronic communication to bully a person. Cyberbullying hurts real people even though we can't always see their reactions.

The use of mobile phones, instant messaging, e-mail or social networking sites to intimidate or harass someone is known as cyberbullying.

The correct answer is "I and IV." Statement I is true because cyberbullying is defined as using electronic communication to bully a person.

Statement IV is also true because even though we may not be able to see the victim's reactions online, cyberbullying can still have real-life consequences and can hurt the victim emotionally or mentally.

Statement II is false because cyberbullying is a crime in many states, and statement III is also false because instances of cyberbullying can affect the victim's digital footprint.

Hence, the correct statements are "I and IV".

var applesToBuy = readLine("How many apples would you lik

e? ");

Explanation:

It asks the user to enter answer the question and it stores the answer into the applesToBuy variable.

Its right dont worry.

In the given scenario, if we use "InputStream" class object that inputs value from the user-end, in which we use "readInt" keyword. In Java, this function of the DataInputStream class reads 4 input bytes and returns an integer value. This method takes the next 4 bits from the input stream, transforms them to integers, and would then returns.

And the wrong choice can be defined as follows:

Therefore, the answer is "Option 3", which is  "var applesToBuy - readInt("How many apples would you like?");".

An Ethernet interface may be defined as a type of interface that involves a circuit board or card installed in a personal computer or workstation, as a network client.

A networking interface allows a computer or mobile device to connect to a local area network (LAN) using Ethernet as the transmission mechanism.

A network interface is the point of interconnection between a computer and a private or public network. A network interface is generally a network interface card (NIC) but does not have to have a physical form. Instead, the network interface can be implemented in software.

If the employee's assignment file from home has a virus, it can infect the company computer when it is opened at work. Option A

Bringing a flash drive with personal files and connecting it to a company computer introduces a potential risk to the company's network and systems. Here's why:

Virus Transmission: If the employee's assignment file contains a virus, malware, or any other malicious software, it can easily spread to the company's computer when the file is accessed. The virus could then infect the company's network, compromise data, or disrupt operations.

Lack of Antivirus Scanning: While some flash drives may have built-in antivirus protection, it is not foolproof. Flash drives can still be carriers of malware, and relying solely on their built-in protection is not sufficient. The company's computer may not have the same level of security measures or antivirus software to scan the files properly.

Intranet Security vs. External Threats: While intranet networks are generally more secure than external networks, they are not completely immune to risks. Intranets can still be vulnerable to internal threats, including infected files brought in from external sources.

Uncontrolled External Connections: Although the question mentions the company operating on an intranet network, it doesn't specify that the computer is not connected to the internet. If the employee connects to the internet using the company's computer, there is an added risk of exposing the network to external threats. Option A

Here is an algorithm in C++ that prompts the user to input the list price of the car and prints the least amount that the dealer would accept for the car:

#include <iostream>

using namespace std;

int main() {

   double list_price, dealer_cost, min_accepted_price;

   const double DEALER_COST_PERCENTAGE = 0.85;

   const double MIN_ACCEPTED_PRICE_OVER_COST = 500;

   cout << "Enter the list price of the car: ";

   cin >> list_price;

   dealer_cost = list_price * DEALER_COST_PERCENTAGE;

   min_accepted_price = dealer_cost + MIN_ACCEPTED_PRICE_OVER_COST;

   cout << "The least amount the dealer would accept for the car is: $" << min_accepted_price << endl;

   return 0;

}

The algorithm starts by including the library iostream and declaring the namespaces. Then it declares the variables that will be used in the program (list_price, dealer_cost, min_accepted_price) and the constants that will be used (DEALER_COST_PERCENTAGE and MIN_ACCEPTED_PRICE_OVER_COST). Then it prompts the user to enter the list price of the car. Next, it calculates the dealer's cost by multiplying the list price by the dealer cost percentage and the minimum amount the dealer would accept by adding the dealer's cost to the minimum accepted price over cost. Finally, it prints the least amount the dealer would accept for the car.

The program manages and controls the seats sold and available for a theatre session.

It starts by displaying a welcome message and a menu with several options, including buying a ticket, printing the seating area, canceling a ticket, listing available seats, saving and loading from a file, and sorting tickets by price.

Each option is implemented as a separate method. The program keeps track of the seats that have been sold and the seats that are still available using three arrays, one for each row. It displays the seating area using 'X' for sold seats and 'O' for available seats, and includes the stage.

The program allows users to buy and cancel tickets, list available seats, and save/load data to/from a file.

Since you work at a print shop that produces marketing materials, and your manager asks you to install a new printer. The drivers that is best is PCL, because it can be used in the office to print physical document while the Postcript can only be used for online document or pdf and since it is office job, PCL is the best.

PCL use depends on the device. This indicates that certain printed data, typically graphical data like fill areas, underlines, or fonts, is created by the drivers for this language by using the printer hardware. As a result, the print job can be processed by the computer fast and effectively. The production and processing of page data must then be finished by the printer.

Note that If you typically print from "Office" programs in general, use the PCL driver. If you wish to print PDFs more quickly or use professional DTP and graphics tools for the majority of your printing, pick the PostScript driver.
