- The accumulated size of its nonstatic data members. The static data memvers, like the member functions, are stored in global space.
- Plus any padding due to memory alignment constraints or simple efficiency. The padding exists between the members or the aggreate boundary itself.
- Plus any internally generated overhead to support the virtuals.
The memory size of a C++ object instance.

本文探讨了对象内存布局的细节,包括非静态数据成员的累积大小、由于内存对齐约束或简单效率而产生的填充,以及为支持虚拟性而内部生成的开销。文中还提到了静态数据成员存储于全局空间中。
