Edit Question
Title
Body
Recently I reviewed some C code and found something equivalent to the following: struct foo { int some_innocent_variables; double some_big_array[VERY_LARGE_NUMBER]; } Being almost, but not quite, almost entirely a newbie in C, am I right in thinking that this struct is awfully inefficient in its use of space because of the array member? What happens when this struct gets passed as an argument to a function? Is it copied in its entirety on the stack, including the full array? Would it be better in most cases to have a double *some_pointer instead?
