- 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 bea 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. Write a program that decrypts the file produced by the program in above.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 in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter. You can assume that the file is filled with only lowercase letters and only the letters from a-z are present! Write the result in a new file to be created by the program! Errors when opening and closing the files must be caught Data.txt I love my moneyPlease in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter.

- Prog 1. File Encryption: 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 each character in the input file into a code, and then writing the coded characters out to a second file. The second file will be a version of the first file but written in a secret code. In Notepad or something similar, you will create a file with text in it. It should be several lines long. Your program should read the file character by character and make some change to the character before writing that character to a second new encrypted file. See program 13-8 to see how to read and write one character at a time. You may come up with an encryption technique of your own or use something simple like adding 10 to the ASCII code of each character in the file before it is written to the second file.Write a program that writes user input to a text file and then reads the contents from that file. You will need to perform the following steps. Prompt the user for the name of a file to append to and then another prompt for them to enter a sentence. Open the file they requested in append mode and write the user_sentence to this file. Don't forget to close the file when you are done writing to it (explicitly or implicitly). Open the file you just wrote to in read mode and read the contents of the file. Print the complete file contents to the console/shell. Provide comments in your code to explain the logic used. Ensure your program works as expected by testing it with different sentences.Simple Encryption. Write a java program that reads from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. For example, Shift size: 1 Message read from the file: Hello Encrypted message: Ifmmp
- Write a C# program that reads a text file and outputs the contains to the screen. The text file should be created outside of your code. Your program should do the following: Create a StreamReader that will read your text file for example // Open the input file for reading using (StreamReader reader = new StreamReader("input.txt")) Output each line from the text file Output one last line that says: "THE END OF FILE"Write a program that asks the user for the name of a text file. The program should display the last 10 lines of the file on the screen (the “tail” of the file). If the file has less than 10 lines, the entire file is displayed, with a message that the entire file has been displayed. The program should do this by seeking to the end of the file and then backing up to the tenth line from the end.Text messaging is a popular means of communication. Many abbreviations are in common use but are not appropriate for formal communication. Suppose the abbreviations are stored, one to a line, in a text file named abbreviations.txt. For example, the file might contain these lines
