Step by step
Solved in 3 steps with 2 images
- Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = False1. Write a program that opens an output file with the filename my_name.txt, writes your name to the file, then closes the file. 2. Write a program that opens the my_name.txt file that was created by the program in problem 1, reads your name from the file, displays the name on the screen, then closes the file. Write code that does the following: opens an output file with the filename number_list.What is the file pointer?
- All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…In Python do the following: Writing to Files: write code to write to a file called ‘writefile.txt’To write in a file we first have to open the file. That is what the first line should do so that Pythoncreates a file object to represent the file, and give the object the name f (variable). We use this variableto refer to the file. To write to the file, use the print statement with the optional file argument thatspecifies the file to write to. When done writing, close the file to make sure all the changes are saved.Remember, if writefile.txt already exists, its contents will be overwritten.Q.Create a program that adds line numbers to a given file. The name of the input file will be read from the user, as will the name of the new file that your program will create. Each line in the output file should begin with the line number, followed by a colon and a space,followed by the line from the input file. Coding language python Don't use pointers and arrays keep the program as simple as possible Paste the screenshots of full program with output
- You are given a String variable named file. It contains the name of a one-line file. Write a sequence of statements that make an exact copy of the file and give it the same name but with the string ".cpy" attached to the filename. Make sure that the data written to the file has been flushed from its buffer and that any system resources used during the course of running these statements have been released.(Do not concern yourself with any possible exceptions here-- assume they are handled elsewhere.)d) Handle the file while reading with an exception best suited.Given an initialised variable fileName, write a sequence of statements that creates a file with the name specified by fileName and a single line containing "This Is File: " followed by the file's name. Verify that the data written to the file has been purged from its buffer and that all system resources consumed by these statements have been released. (Do not worry about any potential exceptions here; assume that they are handled elsewhere.)
- Chapter 4. Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file. The program should read all the numbers from the given file and display the total and average of all numbers in the following format (three decimal digits): Total: nnnnn.nnn Average: nnnnn.nnn Class name: FileTotalAndAverage Here is a working code but please modify it so it passes the test cases because I run it it does not work: Also I do not need Goodbye. I run it through Hypergrade which has all the test cases and it does not pass. It says 0 out of 7 passed import java.io.File; //importing java.io.Fileimport java.io.FileNotFoundException; //importing FileNotFoundException for exception handlingimport java.util.Scanner; //importing Scanner for user inputpublic class FileTotalAndAverage { //class FileTotalAndAverage public static void main(String[] args) throws FileNotFoundException { Scanner keyboard = new Scanner(System.in); //declaring and…Explain in your own words: a.) What does it mean to append data to a file? b.) How do you open a file so that new data will be written to the end of the file’s existing data?a.
