# C/C++/Objective-C analysis overview

This page provides an overview of the CFamily analysis process.

The term *CFamily* refers to the collective group of C, C++, and Objective-C languages.

## Supported versions <a href="#supported-versions" id="supported-versions"></a>

The level of support for a language is defined as follows:

* Fully supported: Analysis will complete. All the language features are understood and examined.
* Supported: Most language features are understood and examined but the version includes unsupported features. Analysis might break or provide incomplete results.

### C <a href="#c" id="c"></a>

* C89, C99, C11, C17: Fully supported
* C23: Supported
* GNU extensions: Supported

### C++ <a href="#c" id="c"></a>

* C++20, C++23: Supported
* C++03, C++11, C++14, C++17: Fully supported
* GNU extensions: Supported

This section covers the following CFamily topics:

* [Analysis modes](/sonarqube-cloud/analyzing-source-code/languages/c-family/analysis-modes.md)
* [Prerequisites](/sonarqube-cloud/analyzing-source-code/languages/c-family/prerequisites.md)
* [Running the analysis](/sonarqube-cloud/analyzing-source-code/languages/c-family/running-the-analysis.md)
* [Customizing the analysis](/sonarqube-cloud/analyzing-source-code/languages/c-family/customizing-the-analysis.md)
* [Understanding the analysis](/sonarqube-cloud/analyzing-source-code/languages/c-family/understanding-the-analysis.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.sonarsource.com/sonarqube-cloud/analyzing-source-code/languages/c-family/overview.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
