Use of AND and OR operator for a Quiz program.

I am attempting to associate a score/award based on the amount of questions that a player gets right. The solution in my head is to use the mentioned operators to come up with every combination (for example: Q1 (WRONG) Q2, Q3, Q4, Q5 (RIGHT). Q1 (RIGHT) Q2 (WRONG) Q3, Q4, Q5 (RIGHT). Q1, Q2 (WRONG) Q3, Q4, Q5 (RIGHT). And so on) and associate them with Boolean values related to the right award. This seems extremely long winded and was wondering if the was an easier to achieve my goal.

Are you awarding different scores for different questions?

Or is it just that different questions have different categories?

You can use a string to check for scores in the end.

//A string that catalogs answer 'status' of each question.
let score = "";

Now just append an integer or a character to the score as the player progresses. For eg:

//Iterate through questions
   //If (condition: player answers a question right)
   score = score + "1";
   //Else
   score = score + "0";
//Now match string to a regex that searches for 0's or 1's
//If score.match("/0/g").length == 0, then 0 questions are correct and so on.

Using this you can even have markings in your question other than 0's and 1's, like a scale from 1 to 3 and then check status of questions answered by matching to appropriate regex's.

It's a game where based on how many questions you get right e.g 5 questions = gold 3-4 =silver 2 = bronze 0-1 = nothing.

Thanks for your answer

let award = ""; //Gold, Silver or Bronze

//If 5 questions right, 5 1's appended
if(score.match("/1/g").length == 5){
   award = "gold";
}
else if(score.match("/1/g").length > 2){
   award = "silver";
}
else if(score.match("/1/g").length == 2){
   award = "bronze";
}
//For 0 or 1 right question
else {
   award = "";
}

Hope these conditions solved your problem. If yes, please mark your question as 'solved', but if you still have trouble please write back.
