Moreover, the query eat (X, jerry) succeeds with the answer substitution X = tom. Prolog executes programs top-down, using SLD resolution to reason backwards , reducing goals to subgoals. In this example, it uses the last rule of the program to reduce the goal of answering the query eat ( X , jerry ) to the subgoals of first finding an X such ...
For example, the Java language does not allow client code that accesses the private data of a class to compile. [12] In the C++ language, private methods are visible, but not accessible in the interface; however, they may be made invisible by explicitly declaring fully abstract classes that represent the interfaces of the class.
