copied!<p>I do not know C/C++ but here is a general idea of the loop assuming the values are coming from an array. (<em>since I am unaware of how they are coming in, i.e. user input, etc.</em>)</p> <h3>Logic:</h3> <ul> <li>Use a <code>for</code> loop structure opposed to a <code>while</code>, to loop over each element of the array.</li> <li>Initialize two variables to keep count, <code>positiveSum</code> and <code>negativeSum</code>.</li> <li>At each iteration of the element, check to see if it's greater than <code>0</code>. That's how you can divide the positive and negative numbers accordingly.</li> <li>If greater than zero, add the element onto the running <code>positiveSum</code>, else add it to the running sum of <code>negativeSum</code>.</li> <li>When the loop finishes, <code>positiveSum</code> and <code>negativeSum</code> should have the calculated sum.</li> </ul> <p>If this is homework, (<em>I don't remember if the homework tag was there prior to the question, or was added on later</em>) this pseudo code should point you in the right direction without explicitly doing the <em>entire</em> work for you.</p> <h3>Pseudo Java Code (<em>not tested or compiled</em>)</h3> <pre><code> // as a good convention, I always initialize variables, // for numbers I always use zero's. double positiveSum, negativeSum = 0.0; // assuming array holds the array of values. for (i=0; i < array.length; i++) { // if positive, add it to the count if (array[i] > 0) positiveSum = positiveSum + array[i]; // else negative else negativeSum = negativeSum + array[i]; } </code></pre> <p>Once it's completed, both <code>positiveSum</code> and <code>negativeSum</code> should hold the correct calculated sum. </p> <p>If you have any questions along the way, I can edit my answer to help you achieve the correct answer, I wish I could give it away but that's what your responsibilities are for homework. </p>
