How Do I Balance Readability and Efficiency in My Code?

If you create something super efficient that’s hard to read, that’s okay too, just make sure to document it well so others can understand it! A few comments go a long way in these cases!

Honestly, I don't think it makes a huge difference here. Moving the read to a separate line doesn't improve readability much, and combining it into the if statement doesn’t really add efficiency either. I’d say stick with what you have. But hey, it’d be interesting to time both versions and see if performance differs at all!

You’ll know whether it’s readable or not when you look back at it in a year. Maybe plan to revisit your code later! At the end of the day, as long as it works and you document it for the next person, you'll be fine. Focus on those big design decisions for efficiency first and leave the small tweaks for later!

Prioritize readability. Adding an extra line won’t impact performance since the compiler will optimize it. Just assume the reader is a programmer and they’ll understand your code. If you're up for it, you can leave a brief comment, but this particular case is pretty self-explanatory.

It all comes down to your audience. If you’re writing for other C programmers, calling a function like this within an if statement is pretty standard and they’ll totally get it. It’s a common idiom in C, so I wouldn’t be too worried about it. Just think about who your future self is writing for!

Just a heads-up: whether you use an extra line or not, it won’t affect efficiency. The compiler optimizes this sort of thing away. For common functions like fgets(), most programmers will know what it does. Keeping it in the if statement is perfectly fine and clear enough, but if you had a more complex function, putting it on its own line could be more beneficial for clarity.
