when does a array act as a pointer in c?

Question

i know that the array name could be used as a pointer(although it\'s a converted form), but my question is , Is there some other instance where array acts as a pointer.

Answer 1

Technically speaking, an array name never acts as a pointer. An expression with array type (which could be an array name) will convert to a pointer anytime an array type is not legal, but a pointer type is. And the declaration of an array as a function parameter is converted into a declaration of a pointer. (Which means that the name isn't an array name, but a pointer name. Despite appearances.)
