Object File
An object file is a binary file produced by a compiler or assembler during the compilation process, containing machine code, data, and metadata such as symbols and relocation information. It serves as an intermediate representation of source code before linking into an executable or library. Object files are platform-specific and are essential in multi-file software projects to enable modular compilation and linking.
Developers should understand object files when working with compiled languages like C, C++, or Rust to debug linking errors, optimize build processes, or create shared libraries. They are crucial in scenarios involving cross-compilation, static analysis, or when integrating assembly code, as they provide insight into the compilation pipeline and enable fine-grained control over the final executable.
