Homework Answers
File class: It is a class that named as a file class which it represents the files and directories, this class is used for the creation of the file or directories. The object can be represented as the particular file which is desighnated to the particular one which is arranged in the disk or something else. In this we can manipulate the files also.
Sequential Acess File: Sequential access file means group of data or files or directories which is arranged in a sequential order that helps us to take out or keep the data in order so that we will have a clear view. It will help us to access the data in a scheduled manner. Updating is somewhat risk that means overwriting the data. We can represent internally formatted data.
