Programming – Example of a Selection Structure
The purpose of this paper is to provide a simple example of a selection structure that is contained as part of the Programming Solution Proposal I am developing throughout the course of this programming class. The selection structure I chose to make an example of isn’t really inclusive as part of my original programming proposal due in week 5, however, I devised a very simple “If-Then-Else” structure that uses somewhat of the same information and calculation as what I may use in my final proposal. I’ve written the pseudocode for a section that at this time appears to make sense to use, given the selection structure I chose, and I also paralleled that with a Visual Logic flowchart.
The visual logic flowchart was executed correctly with specific values that are to be used in order for others to properly test it. These values will change as the program gets fine-tuned, however, for now there are specific values that must be used to obtain the correct percentages. Purpose of the structure
The reason I chose the “If-Then-Else” structure is because it seemed to make the most sense for my program and it didn’t appear to be too complicated a structure to master. Even though this structure may not be included as part of my final proposal paper, I thought it would be good to work with and verify if I could somehow make it work. The program I’ll ultimately be creating is one where seasonal stats will be entered in by an assistant coach, for athletes on any given basketball team.
Through this they will be able to determine a players overall field goal average, free throw percentage, rebound average, etc. However, for now, I’ve decided to simply use an If-Then-Else structure that displays a friendly output message of what the user might see if he/she entered their “field goals attempted” value and “field goals made” value. The pseudocode for the If-Then-Else structure
Again, I must reiterate, that the selection structure I chose to use may not be part of my final proposal paper, however, the pseudocode that is displayed below is a simple and short example of how I used the information for my original proposal, using the If-Then-Else structure: Write “Enter amount of field goals attempted: “
Write “Enter amount of field goals made: “
Set Average = FGM / FGA
If Average => 50 Then
Set FieldGoalAverage = Average
Write “Your field goal average is: ” + FieldGoalAverage + “%” Else
Write “Your field goal average is: ” + FieldGoalAverage + “%” Write “You need to work on your shooting game!”
Visual Logic flowchart
The Visual Logic flowchart I put together, which parallels the pseudocode above, has been executed successfully. The field goal average in this VL example is calculated using the following values: FieldGoalAttempts (FGsAttempted): 5000
FieldGoalsMade (FGsMade): 50
The values for the variables above test the ‘True’ decision statement. Entering the following values below execute and test the ‘False’ decision statement: FieldGoalAttempts (FGsAttempted): 2000
FieldGoalsMade (FGsMade): 50
