-
Define the Condition:
Start by identifying the condition that will determine the program’s flow. This condition is usually a Boolean expression that evaluates to either true or false. Clearly define the variables and operators involved in the condition to ensure accuracy. A well-defined condition is crucial for the rest of the flowchart construction process, avoiding ambiguity and potential errors. The clarity in this step contributes to the overall readability and efficacy of the chart.
-
Draw the Decision Diamond:
Represent the condition with a diamond shape. This diamond is the central element of the flowchart, visually marking the decision point in the programs logic. This diamond will have two paths exiting it, one for ‘true’ and one for ‘false’, which clearly indicate the branching flow in the program. Its essential that the condition is clearly and accurately inscribed within the diamond shape for unambiguous interpretation.
-
Illustrate the True Path:
From the ‘true’ side of the diamond, draw a path indicating what happens if the condition is true. This path would lead to the code block executed when the condition is satisfied. This should be detailed clearly, making it easy to see what actions are undertaken by the program when the condition holds. Use standard flowchart symbols like rectangles for processes and arrows to denote flow. Ensure the pathway is easily followed.
-
Illustrate the False Path:
Similarly, draw a path from the ‘false’ side of the diamond for the situation where the condition is false. This section defines the alternative actions of the program. This might lead to another conditional statement or simply terminate that part of the program’s logic. Accuracy and clear visual representation of this path are just as important as the true path.
-
Connect the Paths:
Ensure that all paths eventually converge or reach an end point. The flowchart should demonstrate a clear and complete flow of the program’s logic, with no loose ends or unclear connections. Once all paths are complete, review to ensure the entire logic is accurately represented, preventing any ambiguity.
