Assume inputFile references a StreamReader object that is associated with an open file. Which of the following loops is written in the correct general format to read all of the items from the file? Loop A: while (inputFile.EndOfStream) { // Read an item from the file. } Loop B: while (!inputFile.EndOfStream) { // Read an item from the file. }

(C#)Assume inputFile references a StreamReader object that is associated with a file that is already open. Which statement can read all the items in the file without knowing how many items the file contains? Question 9 options: while (!inputFile.EndOfStream) { } while (inputFile.EndOfStream) { } while (inputFile != EndOFStream) { } while (inputFile == EndOfStream) { }
Given file.txt that contains only one line as follows: I have a dream.

As a precaution, before using ReadLine on a StreamReader object, you should examine its EndOfStream attribute.

C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.
in java' Variables fStream and dataFS are FileInputStream and Scanner, respectively. String fileName is assigned a file's name read from input. Perform the following tasks: Assign fStream with a FileInputStream that opens the file fileName for reading. Assign dataFS with a Scanner created using fStream. Click here for example Ex: If the input is peach2.txt and: Data in file peach2.txt 4.3 then the output is: 4.3 GroceryDataProcessor.java peach1.txt peach2.txt peach3.txt public class GroceryDataProcessor { publicstaticvoidmain(String[] args) throwsIOException { Scannerscnr=newScanner(System.in); StringfileName; doublepeachWeight; FileInputStreamfStream=null; ScannerdataFS=null; fileName=scnr.next(); /* Your code goes here */ peachWeight=dataFS.nextDouble(); System.out.println(peachWeight); fStream.close(); } }

Before using the ReadLine function on a StreamReader object, it's important to make sure the property's value isn't set to "true" (meaning the object has reached the end of its stream).
. Create a text file that has number from 1 to 20. 2. Use any of the byte stream class and read the data from the text file. 3. Multiply the data that is being read in Question 2-2 with 5 and save the result in a new text file. 4. Perform object serialization.
You would use a stream's clear method to: Multiple answers: Multiple answers are accepted for this question a empty the output buffer b reset flags after a failed translation/extraction c clear the screen d clean up after a bad file open attempt e forget an end-of-file encounter before seeking back to the beginning of the stream
If a file does not exist and a program attempts to open it in append mode, what happens?
