Why it is not allowed to pass arrays by value to a function in C and C++?

Question

C and C++ allows passing of structure and objects by value to function, although prevents passing arrays by values.

Why?

Answer 1

I'm not actually aware of any languages that support passing naked arrays by value. To do so would not be particularly useful and would quickly chomp up the call stack.
