File stream objects:

“fstream” (file stream) is the standard header file in C++ used to perform file operations such as file creation, write information to the file and read information from the file.

“ofstream” is a data type that represents output file stream used to create files and write information to files using output file stream object.

“ifstream” is a data type that represents input file stream used to read information from files using input file stream object.

Purpose of “ifstream”:

“ifstream” file stream object is used to open the file and read the file contents, if the file exists.

If the file does not exist, then the file fails to open, but not creating the file.

Consider the following code using “ifstream” object:

//include required header files

#include<iostream>

#include<fstream>

#include<string>

using namespace std;

//Main function

int main()

{

//declare the variable for file objects

ifstream data;

//file open using "ifstream" object

data...
