light-city dfe1c933b3 docs: address community issue feedback (#5 #338 #142 #246 #136 #303 )

- const README: rewrite the space-saving claim per issue #5 follow-ups
  (constant-expression const vs #define immediates; which const qualify
  as constant expressions)
- const README: fix the class-section diagnosis per issue #338 (overload
  resolution picks the const overload; the restriction only surfaces
  once that overload is removed)
- sizeof README: virtual-inheritance result is compiler-dependent
  (GCC merges vbptr+vfptr -> 16, MSVC keeps them separate -> 32) #246
- static README: new section on internal linkage / access restriction
  with anonymous-namespace comparison #142
- 10-day practice: full problem list table + fixed day links #136
- new design_pattern/singleton/singleton_default.hpp: reusable
  thread-safe CRTP singleton template, compile+concurrency tested #303

C++ struct 与 class 区别

关于C与C++中struct内容：见struct那些事

总的来说，struct 更适合看成是一个数据结构的实现体，class 更适合看成是一个对象的实现体。

区别:

最本质的一个区别就是默认的访问控制

默认的继承访问权限。struct 是 public 的，class 是 private 的。

struct 作为数据结构的实现体，它默认的数据访问控制是 public 的，而 class 作为对象的实现体，它默认的成员变量访问控制是 private 的。
