Description (optional)

In the subsection "Array indices" of this entry it is described how to initialize an array, how to change initialized elements and how to access initialized elements. It is also pointed out that the size of the array cannot be changed during runtime.

What needs to be added is in my opinion

• the recommendation to not access uninitialized elements. E.g. if we have int arr[5] = {0, 1, 2}, then the elements at index 3 and 4 are not initialized and one should not access them before they're initialized, because there can be anything stored inside.
• making the programmer aware of that even if an array arr has length n, you can access and modify with arr[n+1] which leads to undefined behaviour and can e.g. overwrite other variables. This one is especially important since I think that beginners could have some trouble to manage the array length information in their programs which could lead them to use index out of bounds. Since there is not an index out of bounds exception, not knowing this fact could lead them to have hard times debugging their program.

I'm sorry I've changed my mind. I'm already working on another issue. Happy coding.

@Emanuele-Tirendi I am interested in being assigned this issue for my GitHub portfolio project.

[Emanuele-Tirendi]

@leopeq21 @JamesMasterton I guess I cannot assign it to you. As far as I know I am not allowed to assign issues. I just created this issue and was waiting myself to be assigned to it. Either I misunderstood something about the workflows in codecademy or the responsible people actually forgot to assign someone.

[JamesMasterton]

ok, that's fine
