CSE 100: Quiz 2 Solutions (April 23, 1999)

1. When starting to design an algorithm, the first step is understanding the problem, which has three parts, inputs, outputs, and processing to transform inputs to outputs.

2. Write a procedure named rectangleArea with three integer parameters, area, length, and width, which computes the area of a rectangle by multiplying the length times the width.

     Sub rectangleArea(area As Integer, length As Integer, width As Integer)
         area = length * width      
     End Sub
   

3. List the concepts and give an example of each fro the following code (leave blank the concept not shown):

   Dim midPt As Integer ... midPt = midPt \ 2 Call myProc( midPt )

   declaration key word formal parameter actual parameter assignment statement variable

   declaration - Dim midPt As Integer
   key word - Dim, As, Integer, or Call
   formal parameter - (does not appear in above code)
   actual parameter - midPt
   assignment statement - midPt = midPt \ 2
   variable - midPt
