Help I'm stuck, can anybody tell me how to retrieve sc() with the maximum
score? I couldn't figure it out, just started learning and too used to
procedural programming concept. Below are the codes I'm stuck in... using
Visual Prolog 5.2

Database
        sc(symbol Sid,symbol Cid, integer ExamScore).
        
Clauses
        sc("S1","C1",55).
        sc("S1","C2",60).
        sc("S1","C3",70).
        sc("S2","C1",100).
        sc("S2","C2",80).
        sc("S3","C1",40).
        sc("S3","C2",30).

Predicates
        elem_max(integer,integer,integer)
        nondeterm high()
Clauses
        high():-
                sc(S,C,Score),
                write("S: ", S, " C: ", C, " Score: ",Score),
                nl,
                fail.
                        
        elem_max(E1,E2,E1):- E1 >= E2, !.
        elem_max(_,E2,E2).

Goal
        high().
