Write a complete java program that: asks the user for a filename tests whether the file exists and tells the user if it does exist ask the user whether it should be deleted. Either delete or do not delete the file based on the user input. If they don't delete it, ask them if they would like to write to the file If they want to write, ask what they want to write to the file and write it. Make sure to provide plenty of console output dialog specifying what status/actions are taken at each step.

Chapter 4. PC #14. Line Numbers (page 265) Write a java 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 in Eclipse. 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.txtENTER1: a\n2: b\n3: c\n4: d\n

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...

JAVA Even if the condition is false at the first execution a while loop at least executes once. True False A while loop can be used both as an event-controlled loop and as a count controlled loop. True False

Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.

Create any program and then: Show file input (get your input from a file) File output (output to a file) File append (add to the end of a file) Also,Try to have your code handle an error if for example you try to read from a file that doesn’t exist.

Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Python program. You also write the statements that make up the body of the loop. Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. Instructions Make sure the file MovieGuide.py is selected and open. Write thewhile loop using a sentinel value to control the loop, and also write the statements that make up the body of the loop. Execute the program by clicking the Run button at the bottom of the screen. Input the following as star ratings: 0, 3, 4, 4, 1, 1, 2, -1 must be written with this code: """ MovieGuide.py This program allows each theater patron to enter a value from 0 to 4 indicating the number of stars that the patron awards to the Guide's featured movie of the week. The program executes...

Write a while loop that asks people why they like programming. Each time someone enters a reason, add their reason to a file that stores all the responses.

PLZZZ PYTHON PROGRAMMING ONLY (PLEASE HELP IF YOU KNOW ABOUT PYTHON AND FILES) Modify your code to print to a file instead of the console. make sure your program performs the following actions: Ask the user how many numbers they would like to enter Then prompt the user to enter a number as many times as they requested. Print the following to a file: How many numbers they entered The sum of the numbers The highest number The average of the numbers Make sure to use a try-except block and include the finally block. Describe the numbers you print. Do not just print numbers to the screen explain what each number represents. (first picture is my code second picture is of a try-except- finally example that ive done as reference )
