Arrays are not pointers in c. Though they are very similar and will implicitly convert, there are differences. The big and obvious difference is that declaring an array will allocate space for it. In a function, on the stack. In a struct, inline. They have different sizeof. I think there are also some other stuff I can't remember.

In C there's only two operations you can do with arrays that do not decay to a pointer: `sizeof(array_var)` and `&array_var`. The latter produces a rarely-seen "pointer to array", i.e. a type like `int (*)[10]` (pointer-to-array syntax works like pointer-to-function syntax).
