Cyclomatic Complexity: 0
Data Source and Methodology
All calculations are based on the standard formula for cyclomatic complexity: M = E - N + 2P, where M is the cyclomatic complexity, E is the number of edges, N is the number of nodes, and P is the number of connected components.

The Formula Explained
Cyclomatic Complexity Formula: \( M = E - N + 2P \)
Glossary of Variables
- Nodes (N): The points in the program flow where the control can be transferred.
- Edges (E): The lines that connect the nodes, representing the flow of control.
- Connected Components (P): Often set to 1 for a single program.
- Cyclomatic Complexity (M): A measure of the complexity of a program.
Practical Example
Consider a simple program with 10 nodes and 15 edges. The cyclomatic complexity is calculated as follows:
Using the formula \( M = E - N + 2P \), where \( P = 1 \):
M = 15 - 10 + 2 * 1 = 7
Frequently Asked Questions (FAQ)
What is cyclomatic complexity?
Cyclomatic complexity is a software metric used to measure the complexity of a program. It is calculated using the control flow graph of the program.
Why is cyclomatic complexity important?
It helps in understanding the testability and maintenance of a program. Higher complexity may indicate a higher risk of defects.
How can I reduce cyclomatic complexity?
Refactor your code to reduce the number of decision points, such as by simplifying nested conditional statements.
What is considered a high cyclomatic complexity?
A cyclomatic complexity value greater than 10 may require additional testing and scrutiny.
Is cyclomatic complexity the only metric for code quality?
No, it should be used in conjunction with other metrics to get a comprehensive view of code quality.
