files) Encode the file by adding 5 to every byte in the file. Write a program that prompts the user to enter an input filename and an output filename and saves the encrypted version of the input file to the output file.

Chapter 4. PC #6. File Letter Counter (page 264) Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Class name: FileLetterCounter Hints: Hint 1. To read a single character from the keyboard, you need to read a full line and then take the first character in position 0. Hint 2. To count the occurrences of a given characters in a file you need to read the file line-by-line using a while loop, then for each line check all characters in all positions and increment the character counter for each occurrence. This will require to have a for-loop nested inside the while-loop.

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 variables

Q1: Write a python code to read data from a file "file1.txt" and then write the data to another "file "file2.txt 4:30

When an input file is opened, its read position is initially set to the first item in the file. True or False

Use pseudocode to design a program that opens an output file with the external name my_name.dat, writes your name to the file, and then closes the file.

Given a set of values in a file, find the largest number in that set and output the value. Use sentinel controlled while loop. Choose a valid sentinel value. c++  language

Pls help ASAP

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.

assume the file data.dat contains a sequence of binary data. write a program that does the following: displays the first 5 bytes stored in the file. each byte should be displayed on a separate line. starting with byte 0, displays every even-numbered byte in the file. (in other words, display byte 0, byte 2, byte 4, and so on.) each byte should be displayed on a separate line. starting with byte 1, displays every odd-numbered byte in the file. (in other words, display byte 1, byte 3, byte 5, and so on.) each byte should be displayed on a separate line. displays the last 5 bytes stored in the file, in reverse order. (display the last byte, then the next-to-last byte, and so on.) each byte should be displayed on a separate line. handle exceptions in the following manner: if a filenotfoundexception is thrown, the program should display the string "file error". if an eofexception is thrown, the program should display the string "eof error". if any other exception is thrown, the program…
