编译器就是将“高级语言”翻译为“机器语言（低级语言）”的程序。一个现代编译器的主要工作流程：源代码 (source code) → 预处理器 (preprocessor) → 编译器 (compiler) → 目标代码 (object code) → 链接器 (Linker) → 可执行程序 (executables)-The compiler is to " high-level language,"　translated as " machine language (vulgar language)"　procedure. A modern compilers main workflow: The source code (source code) → pre-processor (preprocessor) → compiler (compiler) → object code (object code) → Linker (Linker) → executable programs (executables)
