Calculator RAPTOR Flowchart<\/h2>\n

In this tutorial, you will create a Calculator RAPTOR Flowchart and sub-modules for the calculator’s different arithmetic operations.<\/p>\n

IPO chart<\/h3>\n

Consider modeling an IPO chart for the flowchart before the flowchart design. Think about the input to the flowchart, processing statements, and the output of the flowchart. An IPO chart is a handy tool for visualizing information in a tabular format.<\/p>\n

Output<\/h2>\n
Let’s run the flowchart with sample test cases to verify that it’s working as intended. If you find that the flowchart is not working as intended in the testing, we may need to verify and debug the flowchart.<\/p>\n
