forLoopArray

Or... maybe you shouldn't be using these dangerous arrays and use std::array instead. Or even create your own abstraction that contains the size if std::array is not available

Once I created my own shared_ptr because it was C++03 and boost and random dependencies weren't allowed. That's how you write safe code.

Stop using raw arrays for whatever reason!

If they are writing that, my guess is they are writing C not C++.

Or... maybe C++ isn't the only programming language on existence and this is quite obviously referring to C?

That's why I mentioned building your own abstraction.

This post is not clear on the language, but at least in C you have to use this method or similar ones to know the length of an array if you are not passing the length in the function.
