The High School Math Teacher Who Just Shattered the March Madness 3-Point Record Alabama coach Nate Oats taught his team to keep firing away from deep—and was rewarded with a mind-boggling 25 ...

Checked C allows out-of-bounds pointer arithmetic for array_ptrs and does not consider it to be undefined behavior. Checked C does not consider signed integer overflow undefined behavior.

Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science, involve working with matrixes, or lists of numbers.

Pointer arithmetic is not allowed on these types. For example, _Ptr<int> p declares a pointer to a single object. The _Array_ptr type for pointers to elements of arrays. Pointer arithmetic is allowed ...

That is when you say something like: int bits[] or, historically, int bits[0]. These are really not arrays but pointers that probably point to an array of an unknown — to the compiler — size.
