When I pass an array to a function,Is it passed by value or passed by reference?

I’m confused.When creating a function using an array as a parameter, there’s no “&” before the array, which means “pass by reference” However, the function acts as if it were passed by reference.

They turn implicitly into pointers, their size is unknown when passed to a function and they don't match with the stl container design so that they're lacking consistency. And if you make them 2d, it's even worse.

Do you use the array class or low level bad practice C arrays?
