C++: How is static class member implemented?

Question

Where are static data members stored? Is there some kind of static members table (as in "virtual methods table")? I've performed an experiment - seems like static members don't affect sizeof() at all. Does it mean all references to static members are converted to a fixed address?

Answer 1

The C++ standard doesn't enforce a particular implementation. But typically static class members will be implemented in a similar fashion to "free" statics.

However, your observation that sizeof shouldn't be affected by static members is correct.

Answer 2

C ++中的静态成员的实现方式与C ++和C中的静态非成员完全相同。没有“静态成员表”。
