Question
Chapter 11, Problem 11.15E
Program Plan Intro
- ichar, line,ifilename,ofilename, i, choice, and x are input variables
- rfptr, wfptr are the file pointers to write the data.
Program description:
The main purpose of the program is to read and write the entered text line using file pointers either using the standard input and output or using the input and output file. The program first displays the menu to the user to select the choice which does not allow to enter invalid choice. It then uses the standard input and output or file names to get the data and display the data according to user choice with the help of file pointer.

(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.
(PYTHON) A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names.
Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output.
Ex: If the input of the program is:
ParkPhotos.txt
and the contents of ParkPhotos.txt are:
Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg Redwood1980_photo.jpg…
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.

- Use Scanner and File to read input from a file. Use PrintStream and File to write output to a file. Write and call methods that accept parameters and return values to manage information flow and add structure to programs. Follow prescribed conventions for spacing, indentation, naming, and comments. Notice that if an input file is not found, either for creating a mad-lib or viewing an existing one, the user is re-prompted. No re-prompting occurs for the output file. If the output file does not already exist, it is created. If it does already exist, its contents are overwritten. (These are the default behaviors in Java.) You may assume that the output file is not the same file as the input file. When you are viewing an existing mad lib story, you are simply reading and echoing its contents to the console. You do not need to do any kind of testing to make sure that the story came from a mad lib input file; just output the file's contents.

It is highly recommended to solve ALL of the following exercises. Exercise 1: Write a Python program that reads from the user the name of two files (an input file and an output file). The program will then read each line of the input file and save it in the output file preceded with the line number and removing any of the following punctuations (., !?;:) found at the end of the line. For example, if the input file is: Mary had a little lamb; Whose fleece was white as snow; And everywhere that Mary went; The lamb was sure to go!
