Prolog Part2 - Syntax, Questions and Structs

"_" is a wildcard meaning 'whatever'

We can use write for printing.
ex1: write(City1).
	write('Hello, ), write(Name), nl.   ===> nl means new line

ex2:
weather(phoenix,hot,summer).
weather(la,warm,summer).

warmer_than(C1, C2):-
	weather(C1,hot,summer),
	weather(C2,warm,summer),
	write(C1), write(' is warmer than '), write(C2), nl.

Structs are used to simplify or organize the overall look of our code.
ex:

course(cse110, mon, wed, 11, 12, 11, 12, holton, bryce, coor105, coor321).

course(
	cse110,
	day(mon),
	time(11,12),
	prof(holton, bryce),
	coor105
).

course(
	cse110,
	day(wed),
	time(11,12),
	prof(holton, bryce),
	coor321
).
