A survey on metric of software complexity

With the evolution of the software development, the scale of the software is increasingly growing to the extent that we cannot hand it easily. Some metrics are proposed to measure the complexity of software in last a few years. This article aims at a comprehensive survey of the metric of software complexity. Some classic and efficient software complexity metrics, such as Lines of Codes (LOC), Halstead Complexity Metric (HCM) and Cyclomatic Complexity Metric (CCM), are discussed and analyzed first. Then, some other approaches driven from above classic metrics are also discussed. The comparison and the relationship of these metrics of software complexity are also presented.
