在C和C转换单元++ [英] Translation unit in C and C++

问题描述

有没有什么之间转换单元是C ++和差C？

Is there a difference between what a translation unit is in C++ and C?

在其他职位，我读了一个头文件和源文件，使一个翻译单元，但
可以将源文件单独被称为翻译单元在C ++中它包含在一个文件中的所有定义？

In other posts, I read that a header and source file makes a translation unit, but can a source file alone be called a translation unit in C++ where it contains all the definitions in one file?

推荐答案

一个翻译单位是不是一个头和一个源文件。它可能包括一个千年的头文件（和千源文件也是如此）。

A translation unit is not "a header and a source file". It could include a thousand header files (and a thousand source files too).

一个翻译单元简直就是通常被称为源文件或.cpp文件被preprocessed后。如果源文件的#include S其他文件这些文件的文本被包含在由preprocessor翻译单元。目前在这个问题上C和C ++之间没有差异。

A translation unit is simply what is commonly known as "a source file" or a ".cpp file" after being preprocessed. If the source file #includes other files the text of those files gets included in the translation unit by the preprocessor. There is no difference between C and C++ on this matter.
