    Question Look at my code and tell me what i'm doing wrong?

    Creating a calculator that computes compounded interest at the end of a set number of years. The balance grows each year according to this formula. new balance = prevoius balance*(1+interest rate)
    Create a web application which accepts an initial balance, an annual interest rate, and number of years and displays the compounded account balance at the end of the stated period.

    Specs
    Include two buttons - one to perform the calculation and one to clear the inputs.

    Create a class called FutureValue which contains the following:

    three data members to match the form inputs
    three property assessors to get and set the data members
    a function to calculate and return the future value. Use a loop (of your choice) to perform the calculation.
    When the Calculate button is clicked, do the following:

    create an object of type FutureValue
    use the set assessors to store the values from your form in the object
    call the function to calculate the future value and display it on the form. You may display the value in a label or in a read-only text box.
    When the Clear button is clicked, clear all the input boxes.

    Re: Help??????

    So you've posted your homework assignment. Do you expect us to do the work for you? If you have specific questions then by all means ask them and we'll answer appropriately. We're here to help, not do the work for you. If you have no idea whatsoever then maybe programming isn't for you. If you have an idea how to proceed then let us know your thoughts, what you've done so far and what you're stuck on. Otherwise we'll just assume that you're lazy. By all means prove that assumption incorrect.

    Do you take your car to the machanic and expect it to be fixed without desribing the problem? Do you go to the doctor and expect a diagnosis without describing your symptoms? If you're having an issue then describe it so we have an idea what we're looking for.
