What is the recommended method to access specific lines in a file that cannot be randomly accessed using the existing methods?

The recommended method to access specific lines in a file that cannot be randomly accessed is to read the file line by line. This approach is often necessary when dealing with large files or when the format of the file does not allow for efficient random access due to its sequential nature.

When reading a file line by line, you sequentially process the content from the beginning to the end, allowing you to retrieve any specific line as it is encountered. This method is especially useful for text files where you might not know the total number of lines or the size of the file beforehand. Furthermore, it avoids the need for loading the entire file into memory, which can be resource-intensive and impractical with large datasets.

Using this technique, you can handle the file in a more memory-efficient way, ensuring that you only store the necessary lines as you read through the data. This is particularly advantageous in scenarios where processing and accessing lines based on certain conditions or criteria are required without incurring high memory overhead.

Options that involve buffering the entire file into memory or creating temporary files might not be suitable for large files due to memory constraints or extra file handling complexity. Storing index pointers could be useful but would require an initial pass over the data to create those indexes, which may
