Technician A says that high pressure in recycled refrigerant is only caused by air contamination. Technician B says that recycle

hjlf

Answer:

a. A only

Explanation:

When air, is in excess of allowable amounts, it can cause the system to operate at pressures that are higher than normal. This means that the recycled refrigerant is operating at high pressure. Thus Technician A is correct.

However, Technician B is incorrect because unlike reclaimed refrigerants where the process strip the refrigerant of impurities making it to meet the standards of a new refrigerant, the recycled refrigerant is not as pure as it's contaminants are only reduced.

Therefore, only technician A is correct.

Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number an

Zanzabum

Answer:

See explaination

Explanation:

/File: ValidateCheckDigits.java

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import java.util.Scanner;

public class ValidateCheckDigits {

public static void main(String[] args) {

String fileName = "numbers.txt"; //input file name

String validFileName = "valid_numbers.txt"; // file name of the output file

//Open the input file for reading and output file for writing

try(Scanner fileScanner = new Scanner( new File(fileName));

BufferedWriter fileWriter = new BufferedWriter( new FileWriter(validFileName))) {

//Until we have lines to be read in the input file

while(fileScanner.hasNextLine()) {

//Read each line

String line = fileScanner.nextLine().trim();

//calculate the sum of first 5 digits

int sum = 0;

for(int i = 0; i < 5; i++) {

sum += Integer.parseInt( line.charAt(i) + "");

}

//Get the last digit

int lastDigit = Integer.parseInt(line.charAt(5)+"");

//Check if the remainder of the sum when divided by 10 is equal to last digit

if(sum%10 == lastDigit) {

//write the number in each line

fileWriter.write(line);

fileWriter.newLine();

System.out.println("Writing valid number to file: " + line);

}

System.out.println("Verifying valid numbers completed.");

} catch(IOException ex ) {

System.err.println("Error: Unable to read or write to the file. Check if the input file exists in the same directory.");

Write C++ code to open a document with the name Hello.txt, place the message "Hello, World!" in the document, and exit the docum

gavmur [86]

Answer:

#include<iostream>

#include<fstream>

using namespace std;

int main()

{

ofstream out;

out.open("Hello.txt");

out << "Hello, World!"<< endl;

out.close();

ifstream in;

in.open("Hello.txt");

while(in.good()){

string line;

in >> line;

cout << line << endl;

}

in.close();

return 0;

}

Explanation:

Step 1:

Add all your preprocessor files directive, #include is known as the preprocessor is used to load files needed to run the code.

#include<iostream>: it provides basic input and output services for C++ programs.

#include<fstream>:used to open a file for writing and reading

using namespace std; means you'll be using namespace std means that you are going to use classes or functions (if any) from "std" namespace

Step 2:

ofstream out; his is used to create files and write data to the file

out.open("Hello.txt"); a new file "HELLO.txt" has been created

out << "Hello, World!"<< endl; "Hello World!" has now been writen to the file

out.close(); The file is now closed

This second step opens a new file and writes hello world to the file then closes it.

Step 3:

ifstream in; ifstream in c++ is a stream class which stands for input file stream a is used for reading data from file.

in.open("Hello.txt"); Reopens the file without recreating it. This is a very important step because if not done properly, you might discard the file you previously created and recreate it.

while(in.good()){

in.good() is true if the previous read operation succeeded without EOF being encountered

string line; It declares a string variable line

in >> line; reads the data into the line variable

cout << line << endl; Prints out the line

reopens the file and read the message into a string variable "line". prints out line then exits out of the file.
