Program Plan Intro
File access methods:
The data contents that are present in a file can be accessed by 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 the 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 temporary file is to allocate a file for the temporary usage. It is used to hold a data temporarily for implementation of the program.
