.cpp 文件和 .h 文件有什么区别? [英] What is the difference between a .cpp file and a .h file?

问题描述

因为我已经制作了 .cpp 文件，然后将它们转换为 .h 文件，所以我能找到的唯一区别是您不能 #include .cpp 文件.我缺少什么区别吗?

Because I've made .cpp files then transfered them into .h files, the only difference I can find is that you can't #include .cpp files. Is there any difference that I am missing?

推荐答案

C++ 构建系统(编译器)没有区别，所以都是一种约定.

The C++ build system (compiler) knows no difference, so it's all one of conventions.

约定是.h文件是声明，.cpp文件是定义.

The convention is that .h files are declarations, and .cpp files are definitions.

这就是为什么 .h 文件是 #included -- 我们包含声明.

That's why .h files are #included -- we include the declarations.
