P3, M2

P3 design a procedural application to meet defined requirements. As in Unit 6 we are to design the program for our paint program again But with a few changes to show the procedural functions.

P3 For our design we need the following: User interface design: same as in unit 6 But an amended one on how you are to show the help menu when the user requests for it. Pseudocode: Same as the one you made in unit 6 but this time indicate when the particular function is called. Structured diagram: Same as the one you made in unit 6 but amend it to show when the particular function is called. Next slide shows how to indicate a function within a structured diagram.

P3 Structured diagram Thankyou Within your structured diagram, the above picture shows an example of how it branches out from a process i.e. Calling a function ‘thanyou’. Amend your diagram accordingly

M2 Give reasons for the tools and techniques used in the production of a procedural application. For this first of all you need to state why you chose to use functions for the paint program explaining the benefits of it. (use the reasons you used for M1). Secondly state within functions what parameters, local & global variables, the data types and what programming library you used for the procedural program you made for the paint program and why? Also state what langauage you used to build your program. Finally state what techniques you used such as sequence selection, iteration etc. Showing how you would use them within your program. Many of these you have already mentioned in Unit 6.
