C++ compiler question

Question

In the while loop lesson, there's this code:

I made it a bit more efficient code wise using built in functions and removing some extra things that it had.

I understand that this case is too simple and the difference may be negligible, but I'm thinking of best practices, more than anything,and in the future.

The question is: is the compiler smart enough to optimize and have the same output with both cases? Does it represent an advantage to use, for example x++ instead of x=x+1?

Thanks!

Answer 1

Hi Juan Vizoso.

You are right, there is not a big difference.

I believe using less lines of code is good, in most cases.

Thank you guys, I'm just starting, following the beginner lessons and just trying to apply old knowledge and logic to check my understanding...
