为了避免内存泄漏,可以在分配器中使用智能指针,或者使用RAII技术来管理资源。 #include <memory> template<typename T> class CustomAllocator { public: typedef T* pointer; pointer allocate(size_t numObjects) { return static_cast<pointer>(::operator new(numObjects * sizeof(T))); } void deallocate(po...

功能:在堆 (Heap)上分配一块指定大小(size字节)的连续内存空间。 返回值: 成功:返回一个指向分配内存块起始地址的void*指针。该指针是未类型化的,需要在使用前强制转换为适当的指针类型。 失败:如果无法分配所需大小的内存(例如,内存不足),则返回NULL。
