  Yes we can use functions to access, but then, what is the fun of hiding if u cannot get it when u need it. Think hiding for a simple function(eg add), when a function is called, it's call does not tell actual implementation of that function (ie. how it calculate the value to be returned), similarly when a user clicks add button, he does not know what happens behind scenes. He just know what he needs to know and the rest is hidden.
  Hope it clears it a bit.

  Yup u r right, but that was just an analogy to explain the concept, in OOP data is hidden inside private data members so that even objects cannot directly access it,and require function calls for the same.
