回到本文的主题,数组是底层数据类型,存放在栈中,其内存的分配和释放完全由系统自动完成,效率最高;动态数组是程序员由new运算符创建的,存放在堆中,需由delete运算符人工释放,否则会内存泄露;vector,存放在堆中,由STL库中程序负责内存的分配和释放,使用方便。 关于vector的分析,参考STL源码剖析(P119-vector的内存管理...
C++复合类型之vector和array模板 今天我们就给小伙伴们简单的介绍一下数组的替代品,vector和array,模板类vector类似于string类,也是一种动态数组。您可以在运行阶段的设置vector对象的长度,可在末尾附加新数据,还可以在中间插入新数据。基本上,它是使用new创建动态数组的替代品 。 vector类的功能比数组强大,但付出的代...

CAutoVectorPtr::m_p指针数据成员变量。 备注 此类提供用于创建和管理智能指针的方法,通过自动释放超出范围的资源来帮助防止内存泄漏。CAutoVectorPtr类似于CAutoPtr,唯一的区别是CAutoVectorPtr使用vector new[]和vector delete[]分配和释放内存,而不是 C++new和delete运算符。 如果需要CAutoVectorPtr的集合类,请参...
