Explanation of Solution
File:
When a data needs to be used for a program for a later use, it can be stored in the form of a file. The data present in the file can be used by the program whenever required.
Closing a file:
Closing a file is the reverse operation of opening a file. The file that is opened by a program will close when it gets shut down.
Reason for a program to close a file after its usage:
There are two reasons for a program closing its file after the usage and the reasons are described below:
- The data that is stored in a temporary data store called as file-buffer are written to the file.
- File buffer is a small “holing section” which holds file-bound data first...
