Etola Systems wants a program that displays the ending inventory amount, given the beginning inventory amount, the amount sold, and the amount returned. The algorithm in Figure 2-44 is supposed to solve this problem, but it is not working correctly. First, calculate the expected output using a beginning inventory of 50, an amount sold of 10, and an amount returned of 2. Then use these values to desk-check the algorithm. Correct the algorithm, and then desk-check it again.
