vector 内存释放问题
关于容器的处理,只是拿来用,理解不深,但是今天跑程序出了问题。释放空间未得到真正的释放。于是网上找了一些文章,解决的问题。解决方法:使用swap 加上clear,一起释放空间。原理:即先创建一个临时拷贝与原先的vector一致,值得注意的是,此时的拷贝(申请空间时系统分配容量)其容量是尽可能小的符合...

STL源码剖析 容器 stl_list.h
list ---------------------------------------------------------------------- ??为什么很多在算法库里有的算法还要在类的成员函数里重新实现一遍? -->1.因为算法库里的是通用的,对于具体的类来说效率不高。 比如说 reverse 如果直接用 stl_algo.h 里的 reverse,会再调用 iter_swap, 而 iter_swap 的实现方法是借用临时变量来交换两个迭代器指向的元素,这样会调用 好几次构造函数、拷贝方法、析构...
