1. The program defines a process_file() function that handles the main logic.

2. Error Handling:

   • FileNotFoundError: Handles cases where the input file doesn't exist
   • PermissionError: Handles cases where the program doesn't have permission to access the file
   • IOError: Handles general input/output errors
   • Exception: Catches any other unexpected errors

3. File Operations:

   • Uses with statements for proper file handling (automatically closes files)
   • Reads content from the input file
   • Modifies the content (in this case, converts to uppercase)
   • Creates a new filename by adding 'modified_' prefix
   • Writes the modified content to the new file

4. To use this program:

• Save it as file_processor.py
• Run it from the command line using python file_processor.py
• When prompted, enter the name of a file you want to process
• The program will create a new file with "modified_" prefix containing the uppercase version of the original content
