File access methods: The data contents that are present in a file can be accessed by the following two ways: • Sequential access • Random access or direct access Sequential access file: In sequential access method, the contents of the file are accessed from the beginning to the end. • The contents of the file can be read only in order; skipping contents between files is not possible. • It must read the contents from the beginning of the file, which takes more time. Temporary file: The purpose of a temporary file is to allocate a file for temporary usage. It is used to hold data temporarily for implementation of program.

Program Plan Intro

File access methods:

The data contents that are present in a file can be accessed by the following two ways:

• Sequential access

• Random access or direct access

Sequential access file:

In sequential access method, the contents of the file are accessed from the beginning to the end.

• The contents of the file can be read only in order; skipping contents between files is not possible.

• It must read the contents from the beginning of the file, which takes more time.

Temporary file:

The purpose of a temporary file is to allocate a file for temporary usage. It is used to hold data temporarily for implementation of program.
