Ok so im making a game and im using arrays (you get better marks). I want it so if they get the question right they get a point, but if they get it wrong they dont. it works as in if they get it wrong they get no points, but when they do get the question correct, it gives them a point and if they get another answer correct it wont give them another point. there points will always stay at 1. Here is my code: var Math_q : array 1 .. 4 of string := init ("What 10 + 13?", "What 154 + 36?", "What 7 * 8?", "What 13 * 21?") var Math_a : array 1 .. 4 of string := init ("23", "190", "56", "273") var answer : string var score : int := 0 var scores : int := 0 proc Mathq for i : 1 .. upper (Math_q) put Math_q (i) get answer if answer = Math_a (i) then scores := score + 1 end if put scores end for end Mathq Mathq |

Well, the variable you display is scores. You assign the value of that variable with scores := score + 1. The value of score is given by var score : int := 0 . You should try to give all of your variables and methods descriptive names. Ideally, their names wouldn't differ by a single letter (scores vs score, Mathq vs Math_q, etc). Doing so will make it easier to write correct code. |

Before getting your first point, you have: score = 0 scores = 0 Once you get a point, you do: scores := score + 1 which gives you: score = 0 scores = 1 When you get your second point, you do: scores := score + 1 Now, what is the value of scores? Read very very carefully. |

Correct! Now do you know why "if they get another answer correct it wont give them another point" ? Can you think of a way to fix it? |

Im sorry but ive tried working it into my code but couldn't get it. I haven't been to class in about 3 weeks due to me breaking my ankle and fracturing my leg. ive had to research most of the things ive done. |

I can't just give you the answer (we don't do that here). Instead, I'll ask a rhetorical question: why do you have two different variables to hold the player's score? |

Ignore your teacher for a moment. If you have a variable score, and you want to increase it by one, what do you do? |

score := score + 1? |

Good. Now remove the scores variable from your code entirely. Make sure you change your put statement to use just the scores variable. |
