Code analysis is a process of analyzing files containing application source text written in one of the programming languages. Analysis may have the following purposes:
Code analysis can be performed manually or automatically. What manual analysis is concerned, we basically mean the classic code review method. Code review has the purpose of error search, working out recommendations on code improvement, and also contributes to education of new programmers.
Automated analysis methods are mostly used to detect errors, vulnerabilities and beetles. Static code analyzers are used to fulfill these tasks.
