This section describes the current state of CodeSonar support for the various C standards.
CodeSonar parses and generates internal representation for all features from these standards.
| C89 / C90 | ANSI X3.159-1989 / ISO/IEC 9899:1990 |
|---|---|
| C99 | ISO/IEC 9899:1999 |
| C11 | ISO/IEC 9899:2011 |
| C17/C18 | ISO/IEC 9899:2018 |
CodeSonar supports many features from C23.
