If a static data member of integral or enumeration type is declaredconst(and notvolatile), it can be initialized with aninitializerin which every expression is aconstant expression, right inside the class definition: structX{conststaticintn=1;conststaticintm{2};// since C++11conststaticintk;}...

每个.cpp/.cc/.cxx... 文件称为一个 TU(Translation Units,翻译单元),有些数据只在当前 TU 使用,有些数据还需要在其他 TUs 使用,前者称为内部链接,后者称为外部链接。 每个TU 就是一个模块,链接就是将这些模块组合起来,同时保证其中所引用的各种符号都在正确的位置上。
