Even if we have inside information about the private member variables, we don\u2019t want our programs to use that information. Instead, the only ways that our programs will manipulate a bag is through the public functions. This approach is called information hiding. What advantages do you see to the approach? 1. The programmer who uses the class does not need to clutter his or her thinking with details of the implementation. 2. At a later point, we can decide to implement the class in a different way, and programs which use the class will still work. This should sound familiar: They are the same reasons that we use preconditions and postconditions to specify what a function does without indicating how the function does its work.

We\u2019ll look at private. members later.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
