AI-generated Summary:
Cyclomatic complexity measures the complexity of source code, indicating software quality by quantifying how complex the code is. Higher values suggest increased complexity and a greater chance of bugs. Using e² studio, cyclomatic complexity can be measured via two external tools: SourceMonitor and Lizard. These tools integrate with e² studio through its external tools feature, allowing users to measure and display complexity results directly within the IDE. The document details installation, configuration, and execution steps for both tools on a Windows 10 environment with e² studio 2024-01.
