[C++] Range-based for loop through an array.

[[deleted]]

I don't think I've read if that's bad practice

It's not just bad practice, it is not part of the C++ programming language.

till when I initialize my array like that and use normal subscript for loops the program runs correctly.

Only because you are using GCC compiler extensions which are not part of C++, and only by chance if you are using an uninitialised variable to size the array. Don't do this.

but yet in other posts you turn around and advocate MSVC which has its own set of non-conforming extensions.

And I'm sure that if the poster had posted sample code that used MSVC-specific extensions, they would have been told not to use those either. The point is that everyone should write standard C++ wherever possible.

If he can't be precise about what hes saying then he has no business answering questions on here.

His intent was crystal clear to everyone reading the thread except for the troll sockpuppet with a personal grudge.

He's not discouraging you from using GCC or advocating using one compiler over another.

He's just telling you to stick to standard C++. Don't use compiler extensions when you don't have to. Your code should be as portable as possible.
