Average Modified Cyclomatic Complexity

Average modified cyclomatic complexity for all nested functions or methods.

For example:

class SayHello {
public:
  SayHello() {}
  void printHello();
};

void SayHello::printHello() {
  switch (i) {
    ...
  }
}

void cyclomaticDemo() {
  ...
}

int func();          // declared here, not defined - excluded from aggregates

int main() {
  ...
}

SayHello(), printHello(), cyclomaticDemo(), and main() have Modified Cyclomatic Complexity of 1, 3, 8, and 2. func() is only declared, not defined, so it isn't counted. For the SayHello class, the average is (1 + 3) / 2 = 2, exactly. For the whole file (sample.cpp), the average is (1 + 3 + 8 + 2) / 4 = 3.5, rounded to 4.

• For projects and architectures, this metric must also be enabled from "Project Configuration/Metrics/Projects and Architectures" with the "Show aggregated function metrics" option.
• The cyclomatic metric used is configured from "Project Configuration/Metrics/Complexity". This metric results from having "Count each decision in a multi-way-decision structure" off and having "Count logical conjuctions (OR) and logical and (AND)" off. Checking "Show all available cyclomatic complexity metric variants" will also enable the metric.
