[3 marks] Tuur

Explanation / Answer

Statement on line 70 is valid.hence true.

If we enter a value greater than 4 we will get an undefined behaviour. The compiler may or may not raise the error or warning. If that memory is not allocated to any other element than this assignment will work, if not then segmentation fault may arise as we trying to access memory which is not allocated to us.
