Answer to Question #226987 in HTML/JavaScript Web Application for Valencia

Question

Write a javascript program that asks the user to enter up to 10 golf scores, which are to be stored in an 

array. You should provide a means for the user to terminate input prior to entering 10 scores. The 

program should display all the scores on one line and report the average score. Handle input, display, 

and the average calculation with three separate array processing functions

Answer 1

function getScores() {
        var scores = [];
    for(var i=0;i< 10;i++) {
        scores.push(parseInt(prompt("Please input a score "+(i+1)+": ")));
    }
    return scores;
}


function calculateAverage(scores) {
    var total = 0;
    for (var i = 0; i < scores.length; i++) {
        total += scores[i];
    }
    average = (total / scores.length).toFixed(2);
    return average;
}


function showScores(scores,average) {
      var allScores=""
    for (var i = 0; i < scores.length; i++) {
        allScores += scores[i]+" ";
    }
    alert("All scores: "+allScores+"\nThe average of the scores is: " + average);
}


var scores =getScores();
var average=calculateAverage(scores);
showScores(scores,average);
