JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements The Conditional Challenge Solution

My correct answers are not adding up?

I have the intuition the values are not adding up as they might need to be converted to Integrals?

// Use conditional statements to build a multiple question quiz.



// Reseting the number of correct answers.
var correctAnswers = 0;


// Questions 1-5
var answer1 = prompt("How much is 1+1?");
  if (answer1 === 1) {
    correctAnswers += 1;
  }
var answer2 = prompt("How much is 2+2?");
  if (answer2 === 4) {
    correctAnswers += 1;
  }
var answer3 = prompt("How much is 4+4?");
  if (answer3 === 8) {
    correctAnswers += 1;
  }
var answer4 = prompt("How much is 8+8?");
  if (answer4 === 16) {
    correctAnswers += 1;
  }
var answer5 = prompt("How much is 16+16?");
  if (answer5 === 32) {
    correctAnswers += 1;
  }

// How many correct answers in total?
alert("You've got " + correctAnswers + " correct answers!");
  if (correctAnswers > 4) {
    alert("That's brilliant! Well done!");
  } else if (correctAnswers > 3) {
    alert("That's great!");
  } else if (correctAnswers > 2) {
    alert("Not too bad");
  } else if (correctAnswers > 1) {
    alert("Could have been better");
  } else if (correctAnswers > 1) {
    alert("At least you got 1 right!");
  } else {
    alert("0?!!!");
  }

Hi Thomas - first thing that might need pointing out for you to check.

When your user inputs the answer to a question I believe it returns a string so "1" instead of the integer 1 - so you might need to convert the string to an integer - look at the parseInt() function.

Hope that helps.

Thanks Sam,

Indeed, I wasn't aware that JS is actually taking anything that's "prompted" as a string value by default. Since my function is relying on addition, it makes sense that I need those to be integers.

Thanks again! :)

This part is adding up wrong.... var answer1 = prompt("How much is 1+1?"); if (answer1 === 1) {

answer ===2 instead
