Step by step
Solved in 2 steps
- Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.C# Write, compile, and test a console application 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 file's size, you can create a System.IO.FileInfo 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;Line Numbers 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. Python
- C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.#function read file and display reportdef displayAverage(fileName):#open the fileinfile = open(fileName, "r")#variable declaration and initializationtotal = 0count = 0#read filefor num in infile:total = total + float(num)count = count + 1#close the fileinfile.close()#calculate averageaverage = total / count#display the resultprint("Average {:.1f}".format(average)) #method callingdisplayAverage("numbers.txt")The function fopen return NULL when: An error occurred while opening the file. An error occurred while reading the file. An error occurred while closing the file. An error occurred while compiling the file.
- getline(myfile,str); * 2 points writes a line of text str from the file myfile reads a line of text to str from the file myfile writes a character str to the file myfile reads a character str from the file myfileAverage Number of WordsIf you have downloaded the source code from the Computer Science Portal you will find a filenamed text.txt in the Chapter 08 folder. The text that is in the file is stored as one sentenceper line. Write a program that reads the file’s contents and calculates the average number ofwords per sentence.(You can access the Computer Science Portal at www.pearsonhighered.com/gaddis.)python function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)
- Word List File Writer: Write a program that asks the user how many words they would like to write to a file, andthen asks the user to enter that many words, one at a time. The words should be writtento a file (in python)File Attributes 5. File attributes (a) File name: file name is a very important file attribute When a file changes name, it seems to change its identity (just like when you change your name) The oldest file naming we may remember is the 8 +3 convention in DOS (in DOS, all file names can NOT be bigger than 8 characters, special characters like spaces were not allowed etc.). So a file like C:\\Program Files\\Adobe\\Photoshop can cause problems in DOS, and it has to be represented in different ways using strange character like~ (tilde). Elaborate on your understanding of file names or file naming in different operating systems (Windows, Mac, Linux etc.). For example, some OS like NTFS may allow longer file name, allow space, and even allow non English like characters such as Chinese file names. Is there a maximum length of file names (can you have a file name of 1,000 characters long?) (b) File creation date and modification date. File can be created and modified using different ways of…C++ Visual Studio 2019 Write a program that asks the user for the name of a file. The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example: George Rolland 127 Academy Street Brasstown, NC 28706 If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. The line numbers should NOT be reset for each screen. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric…
