File Processing

Files Defination:

-         Record is a collection of field

-         Field is a block of byte

-         Byte is collection of bit

Stream Defination:

To keep key in data from keyboard need to be saved at secondary storage device as a data file.

So without any further do lets take a look to the main part of this blog

Creating File:

So in order to use a algorithm for file i will give a screenshot of my work

If you want to create a file you also need something like lets say a database.but i will create that databse in .txt to make it ez, but you cant make the database in any diffrent type of file as long it supporting to create a text but i suggest you to create the file in .txt

As you can see at my first screenshot. In that syntax there is ‘w’,’r’

So i will explain that below:

“r”                               opening a file to be read.

            “w”                              creating a file to be written.

            “a”                               opening a File for data append.

            “r+”                             opening a File for read/write.

            “w+”                           creating file for read/write.

            “a+”                            opening a File for read/append

            “rb”                            opening a File (binary) to be read.

            “wb”               creating a file (binary) for write operation.

These are command to do with the .txt file
