2 . Identify the processing needed to convert the inputs to the outputs .
3 . Design an algorithm in pseudocode to solve the problem . Make sure to include steps to get each input and to report each output .
4 . Identify five significant test cases including one for incorrect input ( ie . Input a letter rather than a digit for the numeric input ). ( Think about what impact changing the order of the input values should have on your program !) For each of the five test cases show what inputs you will use and calculate what your expected outputs should be .
