# Static code analysis

In CLion, there is a set of code inspections that detect and correct abnormal code in your project before you compile it. The IDE can find and highlight various problems, locate dead code, find probable bugs, spelling problems, and improve the overall code structure.

Inspections can scan your code in all project files or only in specific [scopes](configuring-scopes-and-file-colors.html) (for example, only in production code or in modified files).

Every inspection has a [severity level](configuring-inspection-severities.html) — the extent to which a problem can affect your code. Severities are highlighted differently in the editor so that you can quickly distinguish between critical problems and less important things. CLion comes with a set of predefined severity levels and enables you to create your own.

Inspections and their settings are grouped in [profiles](customizing-profiles.html). Each profile contains the information on the enabled inspections, a scope of files that they analyze, and their severity levels.

> **Tip:**
> As additional external analyzers, you can use [cppcheck](http://cppcheck.sourceforge.net/) via the [Cppcheck plugin](https://plugins.jetbrains.com/plugin/8143-cppcheck) or [SonarLint](https://www.sonarlint.org/) via the [SonarLint plugin](https://plugins.jetbrains.com/plugin/7973-sonarlint).
