need an assignment to study my final exam

[zxcxz]

Hi to all.

I've to find an assignment to study my final exam. It's about prolog programming and relationships. For example :

X is father, Y is mother. If A and B is a child of X and Y, they're brother. Another example; if C is A's grandfather, and D is B's grandmother, X and Y is married. Hmm also, if E is X's brother, E is A and B's uncle.

It's a complicated coding. I found a full source code about that problem. But I've lost right now

So, can I find any example that similar to what I want ? Also, where can I find understandable prolog source codes to study ?

Thanks a lot for the replies

its not complicated at all.
describe all your people as male(name) or female(name) and one basic relationship f.ex. father/mother.
from there on create predicates such as
a)parent(X,Y):-father(X,Y).
parent(X,Y):-mother(X,Y).

b)brother(X,Y)arent(Z,X),parent(Z,Y),male(X).
[Z is parent both to X and Y and X is male]

then you can start building your way up [grandfather=father of father] or sideways[uncle=brother of father].

its not that big a deal!!
