目标：这项任务的目的是加强学生的理解和…

代码说明：

1实现stl容器； 2实现说给声明的函数 3使用递归方法 相对于实验2，新增了2个类Class Category。Class Categories； 关键算法： virtual void findOfferings (Listing::iterator start, Listing::iterator finish, Listing &matches) void findOfferingsRecursive (Listing::iterator start, Listing::iterator finish, Listing &matches) 压缩包里面有代码，指导书，以及Apache服务器。-Goals: This assignment is designed to reinforce the student s understanding and use of recursion. Outcomes: Students successfully completing this assignment would master the following outcomes. Use the STL vector container Produce C++ class implementations given class declarations Produce a recursive algorithm
