There is a fantastic concept called encapsulation, but OO encapsulation isn't it. For an actual example of encapsulation, look at C stack variables. They are actually encapsulated within their function. It's how the C function is able to operate as a black box - the true meaning of "encapsulation". If you could write getter methods to expose C stack variables to outside callers, they would become just as non-encapsulated as OO class fields.
