Should I Use a Function to Close a File Multiple Times or Just Call fclose Directly?

You really shouldn't hesitate to create small functions, even for simple tasks! If you ever need to log the file closing or change how you handle it later, having a function makes that easy. It keeps your code cleaner and gives you a single point to modify if you need to add functionality later. Plus, consider that if you want to swap out fclose for another library call, wrapping it in your own function makes that a breeze!

Honestly, it’s kind of a toss-up. On one hand, you could directly use fclose wherever you need it, but creating a function can save you headaches in the future. If you decide to add logging or change how the file's closed later on, having just one function to adjust is far less work than updating every single fclose call.

If you're just wrapping fclose with no added functionality, it might not seem worth it. But if you think you could expand that functionality later, it definitely makes sense to keep it modular!

Functions do add a bit of overhead since the arguments need to be pushed to the stack and all that, but it’s minimal. The real benefit comes when you need to change something later. One function means one change instead of multiple updates. So for the sake of future-proofing your code, I’d lean towards making it a function.
