Question

A game program contains the following code to update three score variables, health, food, and knowledge. The maximum values for the three variables are 100, 80, and 25, respectively. health health + 10 IF(health > 100) { health 100 } food food + 1 IF(food > 80) { food 80 } knowledge knowledge + 5 IF(knowledge > 25) { knowledge 25 } The game program’s author would like to write a procedure that could be used to update any variable in the game (myScore) that has a maximum value (myLimit) by a given amount (myAmount). A correct call of the procedure is shown below. myScore updateScore(myScore, myAmount, myLimit) Which of the following is a correct implementation of updateScore ? PROCEDURE updateScore(score, amount, limit) { score score + amount IF (score > limit) { score limit } } Option A,PROCEDURE updateScore(score, amount, limit) { score ← score + amount IF (score > limit) { score ← limit } } A PROCEDURE updateScore(score, amount, limit) { score score + amount IF(score > amount) { score limit } RETURN(limit) } Option B,PROCEDURE updateScore(score, amount, limit) { score ← score + amount IF(score > amount) { score ← limit } RETURN(limit) } B PROCEDURE updateScore(score, amount, limit) { score score + amount IF(score > limit) { score limit } RETURN(score) } Option C,PROCEDURE updateScore(score, amount, limit) { score ← score + amount IF(score > limit) { score ← limit } RETURN(score) } C PROCEDURE updateScore(score, amount, limit) { IF(score = health) { score score + 10 } IF(score = food) { score score + 1 } IF(score = knowledge) { score score + 5 } IF(score > limit) { score limit } } Option D,PROCEDURE updateScore(score, amount, limit) { IF(score = health) { score ← score + 10 } IF(score = food) { score ← score + 1 } IF(score = knowledge) { score ← score + 5 } IF(score > limit) { score ← limit } } D

Answer 1

Correct answer: Option C.

Reason: It adds amount to score, caps it at limit when necessary, and returns the updated score. The other options are wrong because A doesn't return a value, B uses the wrong comparison and returns limit incorrectly, and D hard-codes checks for specific variables (not generic) and also doesn't return the result.
