Null pointers (pointers set to nullptr) are particularly useful when dealing with dynamic memory allocation. In the context of dynamic memory allocation, a null pointer basically says “no memory has been allocated to this pointer”. This allows us to do things like conditionally allocate memory:...
Class 'CLogFile' does not have a operator= which is recommended since it has dynamic memory/resource allocation(s). 翻译: 类'CLogFile'没有operator =,因为它具有动态内存/资源分配,所以建议使用它。 对应源码位置: 原因分析: 意思是构造函数有动态分配内存,所以建议该类增加operator =函数。为什么呢? 因...
An Example with Dynamic Data Allocation class MyString { private: int buf_len; char * characters; public: MyString(int buf_len = 64, const char * data = NULL) { std::cout << "Constructor(int, char*)" << std::endl; this->buf_len = 0; this->characters = NULL; create(buf_len...

The C++ new and delete functions also rely on these lists of memory blocks, so that C++ tends to use dynamic memory allocation more often than C. If the DLL allocates some memory—for example, for the creation of a new instance of a class—this memory is marked in the allocation list ...
Dynamic Memory Allocation The mechanism by which storage/memory/cells can be allocated to variables during the runtime is called Dynamic Memory Allocation. Dynamic memory allocation can be done on both stack and heap. An example of dynamic allocation to be done on the stack is recursion where th...
