File Handling in C++ Programming

What is file handling in C++ programming?

• Method of handling exceptions in C++

• Process of working with files

• Technique for managing memory in C++

• Approach for creating user interfaces in C++

Explain the process of file input and output in C++.

• The process of file input and output in C++ involves creating a new file, reading data from the file, and then deleting the file.

• File input and output in C++ is done by directly modifying the file's contents without opening or closing it.

• In C++, file input and output is achieved by using a single function to both read and write data to the file.

• The process of file input and output in C++ involves opening a file, reading or writing data to the file, and then closing the file.

How do you use file streams in C++?

• By including the header and using the read and write functions

• By including the header and using classes like ifstream for input and ofstream for output.

• By using the header and the cin and cout objects

• By using the header and the fopen and fclose functions

Differentiate between a text file and a binary file in C++.

• A text file is always larger in size than a binary file.

• A text file can only be opened in read mode, while a binary file can only be opened in write mode.

• A text file contains human-readable characters, while a binary file contains machine-readable data in the form of 0s and 1s.

• A text file contains only numbers, while a binary file contains only letters.

What are the different modes of opening a file in C++?

• ios::create

• ios::in, ios::out, ios::app, ios::ate, ios::trunc, ios::binary

• ios::read

• ios::write

Explain the process of file opening in C++.

• Using the 'string' library to create an object of type 'stringstream' for reading or writing to a file

• Using the 'fstream' library to create an object of type 'ifstream' or 'ofstream' for reading or writing to a file

• Using the 'vector' library to create an object of type 'vector' for reading or writing to a file

• Using the 'iostream' library to create an object of type 'cin' or 'cout' for reading or writing to a file

How do you close a file in C++?

• terminate()

• finish()

• end()

• close()

What is the significance of file closing in C++?

• It increases the file size

• It allows for further writing to the file

• It has no significance

• It releases the resources associated with the file, ensures that all the data is written to the file, and prevents any further writing to the file.

Files store data permanently in a/ an

• storage device.

• array.

• function.

• variable.

A class which is used for reading information from data files is called

• ofstream

• ifstream

• fstream

• iostream
