The document outlines the steps for reading and writing to a file in C++. It details the necessary headers, object declarations, file opening and closing procedures, and methods for reading and writing data. Proper error handling and resource management are emphasized throughout the process.

2. •Explain the steps involve in reading and writing to
a file in c++ program
•Reading from a File:
•1. Include Necessary Headers:
•#include <iostream> and #include <fstream> are necessary to
enable input/output operations and file streaming in C++.

3. •2. Declare Input File Stream Object:
•Declare an object of type ifstream, commonly named inputFile,
to represent the input file stream.
•3. Open the File:
•Use the open method to associate the file stream with a
specific file for reading.
•Verify the success of the file opening using the is_open()
method.
•Handle errors appropriately if the file cannot be opened.

4. •4. Read Data from the File:
•Employ a loop to repeatedly use the extraction operator (>>)
with the file stream to read data. For example, while (inputFile
>> data) reads data until the end of the file is reached or an
error occurs.
•Process the read data as needed within the loop.

5. •5. Close the File:
•Use the close() method to close the file stream when reading is
complete.
•Closing the file is crucial for proper resource management.

6. •Writing to a File:
•1. Include Necessary Headers:
•Similar to reading, include the headers <iostream> and
<fstream> for file operations.
•2. Declare Output File Stream Object:
•Declare an object of type ofstream, often named outputFile, to
represent the output file stream.

7. •3. Open the File:
•Use the open method to associate the file stream with a
specific file for writing.
•Verify the success of the file opening using the is_open()
method.
•Handle errors appropriately if the file cannot be opened.

8. •4. Write Data to the File:
•Utilize the insertion operator (<<) with the file stream to write
data to the file.
•For example, outputFile << "Hello, World!" << endl; writes a
string to the file.
•Close the File:
•Use the close method to close() the file stream after writing is
complete.
•Properly closing the file is essential for resource management.
