简单地理解,一个source file和一些由#include包含着的headers和source files,通过预编译后,变成一个叫translation unit的东西。从这里可以看出来,#include不但可以包含headers,还可以包含source files。A source file together with all the headers and source files included via the preprocessing directive #include is known as a preprocessing translation unit. After preprocessing, a preprocessing translation unit is called a translation unit.ISO/IEC 9899:1999 (E)
