Select all correct statements concerning arrays in C:

The declaration int arr[]; is not valid in C.

An array's name is special, for it represents the starting address of the array.

Some or all elements of an array can be initialised at the time of array declaration.

Copying one array to another is as simple as writing arr1 = arr2 (where arr1 and arr2 are declared to be integer arrays).

An array in C can contain elements of various data types, just like a Python list.

while (numb) { }

while (numb % numb == 0) { }

while (numb < 0 || numb > 0) { }

while (!numb) { }
