The ifstream is a file stream class used for file handling. To use ifstream header file fstream is used. It is used for reading input from the file. In order to read from a file an object of type ifstream is created. The general form of how object is created is:- ifstream objectname(“filename”). Constructs an ifstream object: (1) default constructor Constructs an ifstream object that is not associated with any file. Internally, its istream base constructor is passed a pointer to a newly constructed filebuf object (the internal file stream buffer).

Introduction
This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.

Sr.No. | Method & description |
---|---|
1 | fstream::close Closes the file currently associated with the object, disassociating it from the stream. |
2 | fstream::is_open Returns whether the stream is currently associated to a file. |
3 | fstream::open Opens the file identified by argument filename, associating it with the stream object. |
4 | fstream::operator= Returns a constant iterator which points to the start of the array. |
5 | fstream::rdbuf Returns a pointer to the internal filebuf object. |
6 | fstream::swap Exchanges all internal data between x and *this. |
