priority_queue<T>//直接输入元素则使用默认容器和比较函数 与往常的初始化不同,优先队列的初始化涉及到一组而外的变量,这里解释一下初始化: a) T就是Type为数据类型 b) Container是容器类型,(Container必须是用数组实现的容器,比如vector,deque等等,但不能用 list。STL里面默认用的是vector) c) Compare是比较...

The member function returns a reference to the top (highest-priority) element of the controlled sequence, which must be non-empty. You use it to access the highest-priority element, when you know it exists. Example // cliext_priority_queue_top.cpp // compile with: /clr #include <cliext/...
