What is the difference between a .cpp file and a .h file?(.cpp 文件和 .h 文件有什么区别?)
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 #include
d -- 我们包含声明.
That's why .h
files are #include
d -- we include the declarations.
