STL包括两部分内容:容器和算法;容器即存放数据的地方,比如array, vector,分为两类,序列式容器和关联式容器: 序列式容器,其中的元素不一定有序,但是都可以被排序,比如vector,list,queue,stack,heap, priority-queue, slist 关联式容器,内部结构是一个平衡二叉树,每个元素都有一个键值和一个实值,比如map, set, ...
return a.second < b.second;//从小到大排序 } void specialCompare() { // 初始map集合 map<string, int> m; m["a"] = 2; m["b"] = 3; m["c"] = 1; // 转为vector集合 vector<pair<string, int> > demo(m.begin(), m.end()); ...
