如果需要空间动态缩小,vector<Point>().swap(pointVec); //或者pointVec.swap(vector<Point> ()),vector的默认构造函数建立临时vector对象 如果vector中存放的是指针,那么当vector销毁时,这些指针指向的对象不会被销毁,内存也不会被释放,需要手动delete。 8、红黑树 作为C++ STL关系式容器(如set,multiset,map, mu...

Consider a pointer pa_ pointing to a [i], i. e., ith element of a vector a. The increment operation (++pa or pa++) causes a pointer to point to the next array element (and not the next memory byte as you might expect). Similarly, the decrement operation (–pa or pa–) causes...
