"Clang" is a sharp, metallic sound often associated with objects striking each other, such as metal hitting metal. This sound can be heard in various environments, from construction sites to kitchens, where pots and pans may collide. The intensity and pitch of a clang can vary depending on the materials involved and the force of the impact. In the context of programming, "clang" is also a compiler for the C, C++, and Objective-C languages. Developed as part of the LLVM project, it aims to provide fast compilation and helpful error messages. This tool is widely used in software development to translate source code into executable programs.
