Code review and improvements

[munaxshe]

Hi,

As part of my OOP resit assignment, I’ve taken some time to review this code and suggest improvements that could make it clearer and easier to maintain. Here’s a quick summary of what I’ve done in this pull request:

• Changed a few variable names to make them more descriptive (for example, I changed ‘z’ to ‘filePath’).
• Added some comments to explain what certain functions and parts of the code do.
• Put in some basic error handling for file reading, so the program doesn’t crash if the file is missing.
• Tweaked some of the output messages to make them more user-friendly.

I’ve tried to leave detailed comments in the code to explain each suggestion and why I think it helps. Hope this is useful!

Thanks.
