devcpp Oct 12, 2016 需要使用priority_queue,定义在<queue>中: #include <queue> 默认下,priority_queue是大顶堆,比如这样声明: priority_queue<int> max_heap; 这个等效于: priority_queue<int, vector<int>, less<int>> max_heap; 小顶堆的话,需要使用std:greater<T>: priority_queue<int, vector<int>, greater<int>> min_heap; Comments ...

C++ STL map::max_size() function with example: Here, we are going to learn about the map::max_size() function in C++ STL, that is used to return the maximum number of elements of the map that it can store.

并在Priority.cpp中的所有include语句后加上: constint log4cpp::Priority::MESSAGE_SIZE =8; 编译链接成功后会得到log4cppD.dll、log4cppD.lib(Debug版的dll和lib文件)和log4cpp.dll、log4cpp.lib(Release版的dll和lib文件)。新建目录D:\log4cpp-0.3.5rc3\lib,将以上四个文件拷贝到该目录下。
