  1. Given the program structure below,

    answer the program structure questions, where 1:, 2:, 3: , identify the code line but are not part of the code.

    1: length = 30

    2: width = 20

    3: costPerSqFt = 5

    4: maxIndex = 5

    5: index = 0

    6: while index < maxIndex ):

           print(“index “ , index)

    8:     index = index + 1

    9:     if index > 2:

                 print(“index > 2”, index)


    12:        print(“index <= 2”, index)

    13: print(“That’s all folks “ )


    Line numbers 1 – 5 represent a Sequence  of statements


    Line numbers 6 – 12 represents a  Loop/Iteration structure


    Line numbers 9-12 represent a Decision structure 


    Line numbers 1 - 13 represent an overall  Sequence structure


  1. Assess the statements below as to whether they are substantially true or not


    A use case diagram describes what the value of a system is from a users perspective


    A UML diagram is used in an object oriented context to create a logical model of your domain or  solution objects within that domain


    An activity diagram could be used to visualize process flow of activities


    A PAC chart helps to analyze/synthesize an understanding of the requirements of the task/opportunity/problem.


    A PAC chart will list possible solution alternatives and the processing required to effect a solution.


    Pseudocode will run directly, as is, within a Python environments   


  1. Decide whether the following statements are substantially true .


    The first step in getting to a solution to a task/opportunity/problem is to identify that there is a need for something to be done in the first place!


    You need to understand the issue/task/problem well enough to determine what level of domain knowledge is necessary for you and your client to construct a solution. You must  also be self aware of your own knowledge base and that of your client and make adjustments to bring these two knowledge bases into synchronization


    Once you have the requirements of a task/issue/problem, you should implement the first solution that occurs to you.(


    If you have a complex environment, and multiple possible solution procedures to choose from, you should just use a single criterion to do the selection.


    After selecting and implementing a solution, you should then evaluate the result to see if it satisfies the requirements.
