Each line in the output file should begin with the line number, followed by a colon and a space,followed by the line from the input file.

- What is the difference between a text and a binary file? Can you use a text editor to see a text or binary file?arrow_forwardCan you load the contents of a file into memory without doing any explicit copying?arrow_forwardProg 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.arrow_forward
- Explain in your own words: a.) What does it mean to append data to a file? b.) How do you open a file so that new data will be written to the end of the file’s existing data?arrow_forward1. Create a program that writes an Integer object to a stream and reads this object from the stream. 2. Simple Encryption. Read 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: Ifmmparrow_forwardProblem: Encode the file by adding 5 to every byte in the file.

Errors when opening and closing the files must be caught!arrow_forward
- WriteaC++programthatpromptstheusertoenterafilenamethatcontains the total mark of students. Each line in the input file contains a student name followed by the student’s total mark. The program should ask the user for the passing threshold (i.e. student whose total mark is greater than or equal the threshold will pass the course) and copy the students who pass the course to a new file (the name of the output file is specified by the user). Moreover, the output file should be format so that all the marks are displayed with two digits after the decimal point. The width for the names and marks fields should be eight and seven, respectively. A sample input and output files are shown below (the passing mark in this sample is assumed to be 60).

He wants an MIPS assembly program that allows him to enter each student’s projects and test scores. He assigns 3 projects and 2 tests. Each project is worth 50 points, and each test is worth 100 points. The program should calculate and display the student number, student scores, and points total for each student. Develop an algorithm to solve this problem for Professor Adam. Create the source file. Assemble your code. Run the program. Submit a print for the source file. Submit a print of the output report for the 10 studentsarrow_forwardUse 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. Menu options can be chosen in any order and are…arrow_forward
