A: I have answered all three subparts of the question in step 2.
write a visual basic code to illustrate how tp perform the following in sequential access files
- open a sequential file
- read a sequetial file
- write asequetial file
Step by step
Solved in 2 steps
- (Data processing) a. Write a C++ program that opens a file and displays its contents with line numbers. That is, the program should print the number 1 before displaying the first line, print the number 2 before displaying the second line, and so on for each line in the file. b. Modify the program written in Exercise 6a to list the file’s contents on the printer assigned to your computer.Given the following, write a code SEGMENT that does the following: Creates a string variable to store a file name (to be entered by the user) Requests the input file name from the user and stores the name in a variable Opens the input file using the entered file name Tests the STATE of the file open. If the file does not open, output a message to the user exit the program Be sure to: Include the necessary header files Declare necessary variablesStoring data in a file can help the permanent storage of data. While trying to enter data in multiple lines program terminates on \n°. Explain with the help of a code how will you read and write the data in a file in multiple lines.
- In Python Write a program that reads the contents of a text file and inserts the line numbers at the beginning of each line, then rewrites the file contentsDesign an application that can be used to read DVD titles from a text file. You do not have to write to the file, only write code to read the titles of DVDs from a text file called DVD.txtLine 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
- Write Visual basic codes to illustrate how to perform the following in Sequential Access files; a) open a sequantial file b) read a sequantial file c) write a sequancial fileTo set up a file to perform file I/O, you must declare Group of answer choices at least one variable to write to the file. one or more file stream objects. a string array to store the file contents. All of these None of theseWord 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)
- #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")In python file operations, mode is used for creating a new fileThe File class contains file input and output operations. In other words, you can use the File class to read and write content from and to files. True False
