标准库 智能指针( smart pointer ) 是啥玩意儿 一,为什么有智能指针??? c++程序员需要自己善后自己动态开辟的内存,一旦忘了释放,内存就泄露。 智能指针可以帮助程序员"自动释放"自己开辟的内存。 二,从哪里看出来智能了??? int*p = newint(11);auto_ptr<int>pa(p);//auto_ptr已经不推荐使用//delete p; ...

To support easy adoption of RAII principles, the C++ Standard Library provides three smart pointer types:std::unique_ptr,std::shared_ptr, andstd::weak_ptr. A smart pointer handles the allocation and deletion of the memory it owns. The following example shows a class with an array member tha...
Just considering the C side, if you typedef a pointer, you can't add a const that goes "inside" the typedef. const TYPE_P would mean the pointer itself would be unchangeable, not the fields of the value it pointed to. One could just keep making new types to get past it--for ...

2024年某国产数据库因C语言指针错误导致2.3TB客户数据泄露，直接损失超5亿元。而C++通过智能指针（Smart Pointer）和RAII（资源获取即初始化）机制，将内存生命周期与对象作用域绑定。华为车BU的自动驾驶系统采用unique_ptr管理激光雷达数据流，在代码量减少30%的同时，内存错误率下降至万分之一。在嵌入式领域，C++的...

我们提出一种 基于智能状态的监控算法 (smart-status-based, Smatus),该监控算法可以全面地检测到上文提到的所有内存错误。 其核心思想是使用了 状态节点,当在内存当中创建一个内存对象时,就会给这个对象创建一个状态节点,记录内存对象当前的状态,比如是否仍在活跃当中、是否已被释放等。除了跟踪每个指针所指的边界外...
detectstd::swap, or any special non-constfunction in a custom smart pointer). We expect this warning may produce many false positives on custom types, and in some scenarios dealing with standard unique pointers. We expect to improve the heuristic as we implement more checks focused on smart ...
Understanding Pointer Data Types As you may have noticed in the examples shown above, pointers are declared with a data type. Perhaps this contributes to the difficulty of understanding what a pointer really is. If a pointer is simply a number that corresponds to the address of a memory loc...
