Just started prolog and cant seem to get my head around it would it be possible to get some hint's and tips on how to if statementd running ......
my Objective:
“Write a Prolog program to work out a fire escape route from a burning building.”

• Each floor is comprised of rooms (grey areas) and corridors (white areas).
• Rooms and corridors are connected together (e.g. a room’s door opens onto a corridor).
• There are 3 exits: the front door, the back door, and the fire escape (which can only be used from the first floor).
• A flight of stairs connects the 2 floors.
any tips on this ?It would be a great help

Are you trying to program it from an already predefined set of rules or are you going to define the rules yourself

yeah comes out a bit like :
?- fire-escape(f4,[cf2,f3],R).

R = [f4,f5,cf5,stairs,cg3,cg4,cg5,cg8,front-door,exit]
More (y/n)? y

R = [f4,f5,cf5,stairs,cg3,cg1,cg2,g9,back-door,exit]
More (y/n)? y

R = [f4,f5,cf5,cf4,cf3,cf7,fire-escape,exit]
More (y/n)? y

no

just looking for notes and stuff about loops

Loops? In Prolog? You're probably expected to use recursion, and lots of it! Prolog's nice, once you get used to its huge eccentricities.
