Cyclomatic Complexity (McCabe)
Measures the number of linearly-independent paths through a program module

Halstead Complexity Measures
Algorithmic complexity, measured by counting operators and operands

Henry and Kafura metrics
Coupling between modules (parameters, global variables, calls)

Bowles metrics
Module and system complexity; coupling via parameters and global variables

Troy and Zweben metrics
Modularity or coupling; complexity of structure (maximum depth of
structure chart); calls-to and called-by
