Answer 1

If array is really an array, then

• &array[0] is the pointer to element 0 of array[]
• &array is the pointer to the entire array[]

So, these two expressions are of different types. And that's the main difference that may cause your code to fail to compile if you pass the wrong one of the two.

At the low level, however, the two pointers are going to hold the same address.
