Hello,

This is my quiz program. Do you think it's okay? - part 2 with teacher help -

var ques = [
  ['What is the world champion of formula 1 Schumacher\'s first name?', 'Michael'],
    ['Who was created DOS operating system?', 'Bill Gates'],
    ['who was the president of Apple Inc.?', 'Steve Jobs']
];
var Good =[];
var Wrong =[];

var question;
var  answer;
var result;
var html;
var correct= 0;
var incorrect = 0;

function print(message) {
 var out = document.getElementById('output');
    out.innerHTML = message;
}

function printlist (list) {
    var listhtml = '<ol>';
    for(var i = 0; i < list.length; i++) {
        listhtml += '<li>' + list[i] + '</li>';
    }
    listhtml += '<ol>';
    return listhtml;


}

for (var i=0; i< ques.length; i+=1) {
    question = ques[i][0];
    answer = ques[i][1];
    result = prompt(question);
    if(result === answer) {
        Good.push(question);
        correct +=1;

    }
    else {
        Wrong.push(question);
        incorrect +=1;

    }
}
html = '<b>'+"You got" + " " + correct + " " + "right answer(s)"+'<br>';
html += '<b>'+"The right questions are:";
html += printlist(Good);
html += '<b>'+"The wrong questions are:";
html += printlist(Wrong);
print(html);
