Final answer:
To change a flowchart into the Cyclomatic complexity, one must first create a control flow graph (CFG) from the flowchart, then apply the Cyclomatic complexity formula M = E - N + 2P, where M is Cyclomatic complexity, E is the number of edges, N is the number of nodes, and P is the number of disconnected parts (usually P is 1).
Step-by-step explanation:
Changing a flowchart into its Cyclomatic complexity involves understanding how the complexity measure works. Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is calculated using the formula M = E - N + 2P, where M is the Cyclomatic complexity, E is the number of edges in the flow graph, N is the number of nodes, and P is the number of disconnected parts of the graph (typically, P = 1 for connected graphs).
To convert a flowchart into its Cyclomatic complexity, you need to draw a control flow graph (CFG) where each unique path through the program corresponds to a potential run-time path. Once the CFG is created, you count the number of nodes and edges. After you have these values, you apply them to the formula to find the Cyclomatic complexity.
In practical terms, a higher Cyclomatic complexity indicates a program with more potential paths, suggesting more potential points of failure and possibly more tests that will need to be written to cover these paths. Generally, programs with lower complexity are easier to understand and maintain.
