This works with pointers in both C and C++. int (*foo)[10] is a pointer to an array of exactly 10 elements. The novel thing being pointed out in the OP is the "10 or more" aspect.



That's true, until you forget and type foo[i] instead of (* foo)[i]. Of course, compilers will usually catch that mistake at compile time...

There'a an interesting analogy with structs here. K&R invented the -> operator specifically to obviate (* ptr).member. It's too bad that arrays took a different route through C's history and didn't manage to end up in a place where a similar convenience would make sense.
