Files are used in file handling to store and retrieve data persistently, allowing information to be saved beyond a program's execution. They provide a way to organize and manage data efficiently, enabling applications to read from and write to external storage. Using files also facilitates data sharing and collaboration, as multiple programs or users can access the same information. Additionally, files support various formats, making it possible to handle diverse types of data easily.

How do you upload file in console application?
In a console application, you typically upload a file by prompting the user to provide the file path and then using file handling functions to read the file. For example, in C#, you can use File.ReadAllText() or File.ReadAllLines() to read the contents of the file after validating the path. In Python, you can use the built-in open() function to access the file. Ensure proper error handling to manage cases where the file may not exist or the path is invalid.
What is append mode and input mode in sequential file handling?
In sequential file handling, append mode allows you to open a file for writing, adding new data at the end of the file without altering or deleting the existing content. This is useful for logging or accumulating data over time. In contrast, input mode is used to open a file for reading, enabling you to access and retrieve the existing data without making any modifications. Together, these modes facilitate efficient data management in files.
