Is the array copied?
Short answer. No. Its address is passed.
Why pass the size?
The function cannot tell the size on its own.
Arrays pass an address
| Parameter: int a[] |
| Pass the size separately |
| Changes reach the original |
Remember
| No copy is made |
| Always pass the size |
A function changed your array. Why? Arrays pass an address. Write the parameter as int a with brackets. Pass the size too. Any change reaches the original array. Remember. No copy is made. Always pass the size.
