Advantages of McCabe Cyclomatic Complexity : It can be used as a ease of maintenance metric. Measuring the Psychological Complexity of Software Maintenance Tasks with the Halstead and McCabe Metrics Abstract: Three software complexity measures (Halstead's E, McCabe's u(G), and the length as measured by number of statements) were compared to programmer performance on two software maintenance tasks. The following software metrics are summarized. ; Singh, Y.: A Modified Form of Software Science Measures.ACM SIGSOFT Notes, 19(1994)3, pp. Halstead Metrics; Further Reading; Previous topic. Sotonwa et al. Thus, these metrics appear to assess psychological complexity primarily where programming practices do not provide assistance in understanding the code.

He noted that N] and V(G) measure complexity along different dimensions and proposed that complexity be measured with lexico- graphically ordered 2-tuples, (N^,V(G)). Halstead Length and Halstead Effort can reasonably be expressed as totals at the higher levels. Cyclomatic Complexity¶ Cyclomatic Complexity corresponds to the number of decisions a block of code contains plus 1. Command-line Usage.
