As described earlier there are several key symbols for designing a flowchartRectangle = ProcessDiamond = DecisionParallelogram = Input / outputCurve ended rectangle = Start / stopHeaded arrows = Show direction of flowUnlike pseudocode not every output and input is shown. For instance if there was a question that required an answer it would be show as an input with the question.e.gStart -----> INPUT: "What is your favorite animal?"After a question it would always go onto a decision based on the answer of the questione.gStart -----> INPUT: "What is your favorite animal?" ------> Does answer = parrotIt would then go on to show what would happen to whether the answer is true or false, and end.e.gStart -----> INPUT: "What is your favorite animal?" ------> Does answer = parrot --------> Yes ------> OUPUT: "I agree, I love how they echo you!" -----> End No ------> OUTPUT: "I disagree, I think it's a parrot!" ------> EndIf there is no response required from the user then it would only be output, if a response is required it would only be input as shown earlierBBC Bitsize useful section: http://www.bbc.co.uk/education/guides/z3bq7ty/revision/3
