Is the array copied?
Short answer. No. The function gets its address.
What else should you pass?
The size.
Remember
| Write int a[] as the parameter |
| Pass the size too |
| Changes reach the caller |
The function changed the array. Why? An array is not copied. The function gets its address. So adding five changes the original, sixty five. Remember three points. Write empty brackets. Pass the size too. Changes reach the caller.
