Sums

[theinsider2012]

JAVA for Windows XP

the question is:

Write an application that shows the sum of 1 to n for every n from 1 to 50. That is, the program prints 1 (the sum of 1 alone), 3 (the sum of 1 and 2), 6 (the sum of 1, 2, and 3), and so on.

I'm not looking for a answer, just some ideas on where to start. I was able to create an application that sums the integers from 1 to 50 and displays the answer 1275, but I'm not sure how to go about writing an app that shows the sum for every n.

thanks for any help.

please provide the section of code you are having trouble with.

Well like I said, the only code I have is for the app that sums from 1 to 50. So here it is.

public class Sum50
{
    public static void main(String[] args)
    {
        int start = 0;
        int sum = 0;
 
        while (start < 50)
        {
            ++start;
            sum = sum + start;
        }
        System.out.println("The sum of 1 to 50 is " + sum);
    }
}

To print out every partial sum, simply add a print statement in your while loop. Think about it what needs to be printed, and if you're still having trouble, post again and we'll help you.
