Function Documentation

valid_question()

bool* valid_question	(	const Settings &	settings,
		const State &	state,
		const Question &	question
	)

Check if the question asked is valid.

Check if the values (player, set, card) are all within the bounds they can be. Additionally check if the player whom a question is asked has at least one card, check that the question is not pointed towards oneself and check that we do not ask for a card from a quartet. We also make sure that there is at least one valid answer possible.

Returns

array with two boolean values, the first one indicates if 0/false is a valid answer to the question, the second one indicates if 1/true is valid, if there is no valid answer possible NULL is returned
