问题描述

您好，我希望能够获得用户输入，然后将其存储并在我的代码中使用.

hello i want to be able to get the user input then store it and use in in my code.

    body(mercury, 36, small, none, none).
    body(venus, 67, small, atmosphere, none).
    body(earth, 93, small, atmosphere, none).
    body(moon, 93, small, none, none).

           read(X),nl,
           body(Body, Miles, _, _, _); Miles > X.

推荐答案

我首先改用了GNU prolog，这很有帮助.

i switched to GNU prolog firstly which helped.

     miles(Body,Miles):-write('Enter the Goal State:'),nl,
                      read(X),nl,
