Get real-time error detection, code completion, and automatic formatting for your C/C++ projects. Supports all common file extensions including .c, .h, .cpp, .cc, .cxx, .hpp, and .hxx. Key features: Code intelligence with IntelliSense and symbol navigation, real-time diagnostics and linting, automatic code formatting, and background indexing for improved performance on large codebases.
