Exactly. When array is passed into function, you lose length information and array construct is reduced to pointer. Array syntax is just synthetic sugar for dereferencing pointer with offset.

This discussion won't get very far if all you think arrays are is syntactic sugar. The array type is useful - think in terms of a static analyser if it helps - in different ways than pointers.

"array syntax" != "arrays". He means things like a[i]. Arrays are only really arrays in their local scope, if you pass them to functions they suddenly are pointers (but for some insane reason, C compilers let you specify "the size of the array in a function argument" which doesn't actually compile to any code).
