[SOLVED] Why int arr[5]; is working for arr[5]?

Question

Shouldn't it work only upto arr[4]? Ie. arr[0] arr[1] arr[2] arr[3] arr[4].

Checkout this program

Why this is working so well? Without any errors.
The program executes even for arr[6] arr[7] etc without any compile time errors although it gives wrong output.
But it works perfectly fine for arr[5]. Why?

Answer 1

Unlike Java or other "safe" language, C++ does not prevent you (the coder) from doing out of bounds array iteration or modification (occasionally).
