Introduction

The raptor Flow chart enables you to create executable flowcharts. Mathematical notation for the sum of squares is shown:

Mathematical Notation

Mathematical notation for the sum of squares up to n numbers is:

 

 

or in simple notation

 

 

Raptor flow chart steps for the program is shown below:

Steps to build

Start the Raptor flowchart tool.
You would be provided with a flowchart with Start and End symbols.

Save the flowchart with a name.
Add Assignment symbols for Assignment( left-clicking once on the symbol and then adding it between Start and End.)
i <- 1
sum <- 0
series <- ” ”

Add Input symbol to the flowchart. Double click to add the prompt “Enter number” and use the variable name N.

Loop Structure

Add a loop structure to the flow chart.

Edit its expression to

i > N

In the loop structure for NO decision, do the following things:

Add Assignment symbols to the flowchart to the flowchart for sum, series and i
sum <- sum + ( i* i )
series <- series + ” ” + ( i*i )
i <- i + 1
Add an Output symbol to the flowchart to output series

In the loop structure for YES decision,
Add an Output symbol to the flowchart to output sum

 

 

Once you are done with a flow chart, You can execute the Raptor flow chart by clicking on Execute to completion button.  You can verify the inputs and outputs in the run. ( Explore Run menu options for more details)
While designing the flow chart you can even test and debug using the “Step to Next shape” button.

Output of the Flowchart Execution

Series= 1
Series= 1 4
Series= 1 4 9
Series= 1 4 9 16
Series= 1 4 9 16 25
Series= 1 4 9 16 25 36
Series= 1 4 9 16 25 36 49
Series= 1 4 9 16 25 36 49 64
Series= 1 4 9 16 25 36 49 64 81
Series= 1 4 9 16 25 36 49 64 81 100
