迭代器和迭代器适配器---《C++标准程序库》读书笔记

   迭代器是一个所谓的smartpointers。具有遍历复杂数据结构的能力，其下层运行机制取决于所遍历的数据结构。因此，每一种容器都必须提供自己的迭代器。

Understanding and using c pointers 第一章读书笔记

 指针和内存当C程序被编译后，它与三种内存打交道1.Static/Global静态变量以及全局变量被分配到该部分内存，他们在程序开始运行时被创建直到程序运行结束后才回收生存期贯穿整个程序执行过程2.Automatic（自动变量）在函数中声明的变量在函数运行时创建，其范围仅限于函数内部，其生存期也仅限于函数执行时3.Dynamic（动态内存分配）内存从堆中分配并在必要时可以被释放如图：C语言参考中对

智能指针(Smart Pointer)

它能避免野指针(danglingpointers)，内存泄漏(memoryleaks)，分配失败等情况的发生。智能指针需要为所有实例维护一个引用计数，这样才能在恰当的时刻(引用计数为0时)将内存释放。
