Describe the mode that each of the following statements causes a file to be opened in:
file.open(“info.dat”, ios::in | ios::out);
file.open(“info.dat”, ios::in | ios::app);
file.open(“info.dat”, ios::in | ios::out | ios::ate);
file.open(“info.dat”, ios::in | ios::out | ios: :binary);

- Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;arrow_forwardWhich of the following opens the employ.txt file and allows the computer to write new data to the end of the files existing data? a. outFile = I0.File.AddText("employ.txt") b. outFile = I0.File.AppendText("employ.txt") c. outFile = I0.File.InsertText("employ.txt") d. outFile = I0.File.WriteText("employ.txt")arrow_forwardDescribe the mode that each of the following statements causes a file to beopened in.fi l e .open("in fo .dat ", io s: :infile.open("info.dat", io s: :infile.open("info.dat", io s: :infile.open("info.dat", io s: :inios: :out);ios::app);ios: :out I ios: :a te );ios::out I ios::binary);arrow_forward
- A file contains only spaces, commas, colons, digits, and newlines in the following frequencies: colon (100), space (605), newline (100), comma (705), 0 (431), 1 (242), 2 (176), 3 (59), 4 (185), 5 (250), 6 (174), 7 (199), 8 (205), 9 (217). Construct Huffman code.arrow_forwardWrite a program that creates the following three files; dataplus.txt dataminus.txt zeros.txt The program should read each line of the data.txt file and perform the following; If the line contains a positive number, that number should be written to the dataplus.txt file If the line contains a negative number, that number should be written to the dataminus.txt file If the line contains the value 0, do not write the value to a file. Instead, keep a count of the number of times 0 is read from the data.txt file After all the lines have been read from the data.txt file, the program should write the count of zeros to the zeros.txt file. The code is below does not work:arrow_forwardexampleOne This program reads data from a physical file, create a reference to the file, perform a computation, display the result, close the file. package chario; import java.util.Scanner; import java.io.*; //public class Chario { // public static void main(String[] args) throws IOException { File file1 = new File("fileOne.txt"); //Create a reference to the physical file /* Use Notepad to create a text file named fileOne.txt which must be in the same directory that src is in To find src, open your project in NetBeans and hover its name, which is in the top left just below the Projects menu; this will display the path to your project My project path is, yours will be different I:\\Ajava\161\WPPractice\IO\charstream\chario My fileOne.txt is located in chario */ Scanner getit = new Scanner( file1 ); // connect a Scanner to the file int num, square; num = getit.nextInt(); square = num * num ; System.out.println("The square of " + num + " is " + square); getit.close(); //Close the stream…arrow_forward
- Chapter 4. PC #14. Line Numbers (page 265) Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. I should be easily type input1.txt and easily print out the output. Test Case 1 Please enter the file name or type QUIT to exit:\nquitENTER Test Case 2 Please enter the file name or type QUIT to exit:\nbadfilename.txtENTERFile: badfilename.txt does not exist.\nPlease enter the file name again or type QUIT to exit:\nquitENTER Test Case 3 Please enter the file name or type QUIT to exit: \ninput1.txt ENTER1: a\n2: b\n3: c\n4: d\narrow_forwardin 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(); } }arrow_forwardWrite a function, WriteFile(), that saves information to a text file. The function receives a string value (obtained from Question 3.2) that is written to the text file. The function does not return any value to the calling statement.Store the output text file as Output.txt.The output must be added on a new line to the text file each time without erasing any existing The above functions (ReadFile(), Decode(), and WriteFile()) must now be implemented in the main program in the following order:1. Create a list of type character, i.e. the data type that is stored in the list is text.2. Read the contents of the file to the lists with ReadFile(). Display the number of lines that are read from the text file.3. Decode each card number with the Decode() function by passing the list to the function.4. As each card number is decoded, write the information to an output file with WriteFile(). The WriteFile() function should be called from within the Decode() function.arrow_forward
- Which example uses the SOLID SRP principle correctly and does not violate it? (A or B) A. public class DatabaseParser { ParseDirectoryMapFile(); // parse directory map fileParsePasswordFile(); // parse user fileParseReviewDataFile(); // parse review data fileParseTeamFile(); // parse team CalculateGrade(); CalulateRelativeGrade(); } B public class DatabaseParser { ParseDirectoryMapFile(); // parse directory map fileParsePasswordFile(); // parse user fileParseReviewDataFile(); // parse review data fileParseTeamFile(); // parse team file} // seperately with the following: public class Calculator{ CalculateGrade(); CalulateRelativeGrade(); }arrow_forwardExamine the following three functions that take as argument a file name and return the extension of that file. For instance, if the file name is 'myfile.tar.gz' the returned value of the function should be 'gz'. If the file name has no extention, i.e. when the file name is just 'myfile', the function should return an empty string. def get_extension1(filename): return(filename.split(".")[-1]) def get_extension2(filename): import os.path return(os.path.splitext(filename)[1]) def get_extension3(filename): return filename[filename.rfind('.'):][1:] Which of the these functions are doing exactly what they are supposed to do according to the description above? get_extension3 only get_extension2 only None of them. get_extension1 onlyarrow_forwardQ1: Suppose that the file (rectangle.txt) shown in the figure was stored in the default path, this file contain the length and width of unknown number of rectangles.
