[C++] [ICS-46] 为什么std::stack会有const T& top() const方法?Why std::stack has const T& top() const method?

结论 Conclusion
该方法与复制/赋值初始化有关,若没有这个方法,那么通过复制/赋值初始化的stack将会无法使用top()方法。
This method is related with copy/assignment initialization. If stack did not have this method, the const stack, which initialized through copy or assignment, could not call top() method.
