# C++ Support in Clang

This page tracks the status of C++ support in Clang.
Currently most of the C++ features are missing; here you can find features that are at least partially supported in Clang.

In this table, parser support means that the parser knows the grammar for the feature. "Sema" support means that we do type checking, report errors about misuses of the feature and build an AST. CodeGen support means that we actually produce LLVM code for the feature with the -emit-llvm option.

### Feature

### Example

### Status

Bool type | bool x; | Full support.
Named Casts | static_cast<int>(x) | Partial Parser and Sema support, no codegen.
References | int &x = ...; | Parser and Sema support in, partial Codegen support.
Default arguments | void f(int x=0); | Full support.
Namespaces | namespace A { int x; } | Parser and Sema support in, no Codegen support.
Class definitions | class C { public: int getX() { return x; } private: int x; }; | Partial Parser and Sema support, no Codegen support.
