码:
template <typename element_type,typename container_type = std::deque<element_type> > class stack { public: stack() {} template <typename CT> stack(CT temp) : container(temp.begin(),temp.end()) {} bool empty(); private: container_type container; }; template <typename element_type,typename container_type = std::deque<element_type> > bool stack<element_type,container_type>::empty() { return container.empty(); }
当我编译它给出错误.
default argument for template parameter for class enclosing
'bool stack<element_type,container_type>::empty()'
为什么编译器抱怨,我该怎么办?
