Mell What is file processing in C++?
In C++ file processing, files are nothing but a sequence of bytes without any structure. A file either ends with a specific byte number maintained by the underlying platforms administrative data structure or with a marker called EOF (end-of-file). As we open a file, an object is created.
Why is file handling needed?
Here are some of the following reasons behind the popularity of file handling: Reusability: It helps in preserving the data or information generated after running the program. Large storage capacity: Using files, you need not worry about the problem of storing data in bulk.
What are the benefits of file handling?
Advantage of File-oriented system:
- Backup: It is possible to take faster and automatic back-up of database stored in files of computer-based systems.
- Compactness: It is possible to store data compactly.
- Data Retrieval:
- Editing:
- Remote Access:
- Sharing:
What are the two methods available for opening the files?
Files can be opened in two ways. They are: Using constructor function of the class. Using member function open of the class.
How does file handling work in C + +?
With file handling, the output of a program can be sent and stored in a file. A number of operations can then be applied to the data while in the file. A stream is an abstraction that represents a device where input/output operations are performed. A stream can be represented as either destination or source of characters of indefinite length.

File Handling In C++ 1 ofstream: This Stream class signifies the output file stream and is applied to create files for writing information to files 2 ifstream: This Stream class signifies the input file stream and is applied for reading information from files 3 fstream: This Stream class can be used for both read and write from/to files.
How are files stored in a C + + program?
C++ Working With Files Many real-life scenarios are there that handle a large number of data, and in such situations, you need to use some secondary storage to store the data. The data are stored in the secondary device using the concept of files. Files are the collection of related data stored in a particular area on the disk.
