Can structures be passed to the functions by value? Why cannot arrays be passed by values to functions? Please explain.
Yes, you can pass a struct by value, but it is rarely done. Presumably arrays cannot be passed by value for two reasons: Arrays can be huge, and since passing by value means making a copy of it, it would be very inefficient. The compiler does not know the size of a dynamic array. Actually, you can put a (non-dynamic) array into a struct and pass it by value that way!
