I’m tryin to run a total of prompt numbers until -1 is entered. The total should not include the the -1 in the sum. Any help is appreciated.
var s = 0;
var t = 0;
var p = 0;
while (p<0);
{
var number = prompt("Enter a positive number to be added to the total or -1 to end. ");
t += parseInt(number);
t++;
console.log("Enter a positive number to be added to the total or -1 to end. " + number);
}
{
console.log("The sum of all numbers entered is " + t);
}
var s = 0;
var t = 0;
var p = 0;
while (p < 0); {
var number = prompt("Enter a positive number to be added to the total or -1 to end. ");
t += parseInt(number);
t++;
console.log("Enter a positive number to be added to the total or -1 to end. " + number);
}
{
console.log("The sum of all numbers entered is " + t);
}
I made some style edits to make it easier to see what’s happening.
while (p < 0); {
This right here is a big problem. You’ve broken up the while syntax with a ;, which basically means you told the loop to have an empty body.
Also, p is never < 0, so your loop body will never run.
Also, p is never changed, so if you loop runs, it will never stop.
Also, I’m not sure why you have this line:
t++;
We are not in the era of punchcards, so I strongly recommend that you use full words for your variable names.
This challenge is similar to my first challenge, except I don’t want i to stop @ 10 prompts. I want it to stop @ -1 but not add the -1 to the sum.
var i = 0;
total = 0;
while(i<10)
{
var number = prompt("Enter a positive number to be added to the total or -1 to end. ");
total += parseInt(number);
i++;
console.log("Enter a positive number to be added to the total or -1 to end. " + number);
}
{
console.log("The sum of all numbers entered is " + total);
}
Well then I think you’d need to know the last number that was selected, in the scope of the while. One option would be to declare a variable outside the while to store the last selection and use that in the while check.
