- Challenge 7
File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file.
- Challenge 8
Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file
please use c#
Be sure to thoroughly document your coding, explaining what you did and why you did it. Comments should explain what your code does (each line or each block of lines...etc.)
17.3 (File of Student Grades) Create a program that stores student grades in a text file. The file should contain the name, ID number, class taken and grade of every student. Allow the user to load a grade file and display its contents in a read-only TextBox. The entries should be displayed in the following format:

The program should output the student name, the five test scores, and the average test score. Output the average test score withtwo decimal places.

A sample input is:Andrew Miller 87.50 89 65.75 37 98.50 Output: The student name, the five test scores, and the average of the five test scores, saved to a file. The program needs to read a student’s first and last name and five test scores. Therefore, you need two variables to store the student name and five variables to store the five test scores. To find theaverage, you must add the five test scores and then divide the sum by 5. Thus, you need a variable to store the average test score.

To write to the file, use the print statement with the optional file argument thatspecifies the file to write to. When done writing, close the file to make sure all the changes are saved.Remember, if writefile.txt already exists, its contents will be overwritten.arrow_forward
