Can you describe a situation where using object-oriented programming is not suitable or not feasible?

Object-oriented programming (OOP) is not always suitable, for example:

• Simple scripts or utilities, where using classes is redundant and complicates the code.
• Functional tasks, where it is preferable to use pure functions and immutable data.
• High-performance or system tasks, where the overhead of OOP (such as virtual calls) can affect performance.
• Processing large volumes of data in a streaming style, where functional or procedural approaches are better.

For example, if you need to quickly write a script to process a text file, using classes might be unnecessary, and it is simpler to use functions and modules.
