    Create an application that will determine and display the sum of numbers as entered by the user. The summation must take place so long the user wants to. When the user ends the program, the summation must be displayed as follows:

    num1 + num2 + num3 +…+ numN = sum

    Example

    Say the user has entered 6 numbers. The output must be displayed as follows:

    10 + 15 + 25 + 45 + 20 + 5 = 120

    What have you tried? Post the code for your current attempt with any specific questions you have about it.

    Be sure to wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

            num = sc.nextInt();
     
            //display the sum
            System.out.println("The sum is " + sum);

    Did you have any questions?
    What happens when you compile the program?
    If there are no compiler errors, what happens when you execute the program?
    If you don't understand my answer, don't ignore it, ask a question.

    Please post the program's output so we can see what is wrong?

    Also please post the code for the complete program.
