Why can't you return an array in C?

Can a function return a type?

A function may be defined to return any type of value, except an array type or a function type; these exclusions must be handled by returning a pointer to the array or function. When a function does not return a value, void is the type specifier in the function declaration and definition.

Can a function return a class in Java?

How to return an array of structures from a function in C?
