Lost by tried and tried

Jul 22nd, 2008

Please help the question appears below and my so-called attempt appears after that as you can see I am relatively new to java, I only manage to do the sum part.

Write a script that takes three integers from the user and displays the sum. average, product, smallest and largest of the numbers in an alert dialog.

When I run the above noting happens, the screen is absolutely blank and there’s no errors. This is for an assignment.

Java != JavaScript. They have similar names (purposefully done so by the JavaScript creators), and a somewhat similar syntax (again, purposefully done), but that's all. Next time post to a JavaScript forum. I have already requested that the admins move this one, so don't bother creating a new one there.

Your question is JavaScript related all right, but your code contains some errors. Whatch for portions marked in red.

Thanks Troy III, for taking the time out to look at my script.

I’ve made the recommended changes but the problem still persists as it doesn’t prompt the user for the integer an I have no idea how to displays the average, product, smallest and largest of the numbers in an alert dialog. All I manage was the sum part.

Here are some more changes.
1. script type="text/javascript". You have a typo.
2. its parseInt and not parselnt.
3.

<body onload="window.prompt;">

Doesn't make any sense to me. You don't need it.
And ofcourse, don't forget points mentioned by Troy III !

Ignorance is definitely not bliss!

As a matter of a fact - your code will give you absolutely NOTHING!

Let me first explain you few things,
-now that you've learned that Java and JavaScript are two completely different languages, there is no single line in your code where you didn't put at least one [?deliberate!] error.

vars can be declared either separately:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
var one;
var two;
var three;
var one;
var two;
var three;

or grouped with one keyword in a comma-separated list:

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)

var one, two, three;

This will produce another error:

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)

var one, tw o, three;

there is no comma between "tw" & "o", or there is an illegal whitespace in the name of var.
(your number 1 error reproduced).

You've commented your script <!-- ... <-- , this can never happen to be one of a "new to Java" error.

You have deliberately missmathched quotes
window.prompt( 'Enter the first number", "0" ); in every single line required.

You've managed to switch "I" with "L" in every parselnt( firstNumber ); function counting on similar visual representation of I and smallcaps L in fonts currently used.

Finishing with your special mess:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
window.status =( sum: " + sum + ");
window.status =( sum: " + sum + ");

using undefined sum: but converting the existing "sum" var into a string literal with no meaning at all.

Not to forget your prime error <script type="text/javajscript"> requiring the browser to use an unknown and inexistent scripting language to interpret your javascript. The most fundamental of all errors previously mentioned.

To round it up, your <body onload="window.prompt;"> is absolute nonesense.

That's because you didn't write anything of that kind in your (provided) code!

Ok this is what I have so far! You will agree its better that what I had when I first posted:

<script LANGUAGE="JAVASCRIPT">
var firstnumber = prompt("Enter first number and Click OK", "0");
var secondnumber = prompt("Enter second number and Click Ok", "0);
var thirdnumber = prompt("Enter third number and Click Ok", "0);
var total = Math.floor(firstnumber)+ Math.floor(secondnumber)+ Math.floor(thirdnumber);
alert("The Sum is: " + total ) // this line give me the correct sum! But I need average, product, smallest and largest of the numbers as well.

alert("The Sum is: " + total + " Average: " + average + " product: " + product +" largest " + largest + " smallest " + smallest) //when I try to replace the above line with this one I get errors.

function YourCost1(){
if(firstnumber > secondnumber && firstnumber > thirdnumber){
var largest= firstnumber;
}
else if(secondnumber > firstnumber && secondnumber > thirdnumber){
var largest= secondnumber;
}
else if(thirdnumber > firstnumber && thirdnumber > secondnumber){
var largest= thirdnumber;
}
if(firstnumber < secondnumber && firstnumber < thirdnumber){
var smallest= firstnumber;
}
else if(secondnumber < firstnumber && secondnumber < thirdnumber){
var smallest= secondnumber;
}
else if(thirdnumber < firstnumber && thirdnumber < secondnumber){
var smallest= thirdnumber;
}
}

"average" has to do with, do it yourself math: ( a + b + c ) / 3, as in primary school.

sunny, you are again deliberately messing with quotes
("Enter second number and Click Ok", "0

you don't need it especially if you haven't writen O instead of 0!

your elseif
is one hell of a junk, there is only one elseif in both real life and in coding.

and there can't be the largest or the smallest "product" you mean "sum" of 1+2+3; -what on earth were you thinikng? the smallest and the largest is always the exact same value of 6,
etc etc ...

Ok I sort of worked it out. I still don’t know how to do the Product bit, Largest and Smallest. O and one more problem I cannot seem to get the sum and average onto the same alert box. I had to add two “alert” to check if the math is correct.

OK
try: alert("The Sum is:" + total + "; The average is: " + average); , to alert them both in one turn.

try:

(Toggle Plain Text)

var largest = Math.max(firstnumber, secondnumber, thirdnumber);
var smallest = Math.min(firstnumber, secondnumber, thirdnumber);

alert("smallest:" + smallest + "; largest: " + largest )
