constructor cannot be a virtual function. To construct an object, you must know exactly what to construct. Otherwise, you cannot construct an object.The Destructor can be pure virtual functions.10. Problems Related to the copy constructor, such as deep copy, shallow copy, and temporary objects.Deep copy means that the resources and pointers are copied, while the light copy only copies the pointers and does not copy the resources.In this way, the two pointers direct to the same resource, causing

1. Introduce STL and explain in detail how STL implements vector. 4. What are the differences between pointer and reference? If it is safer to pass a reference than to pass a pointer, why? Isn't it true if I use a constant pointer? 5. There are several ways to pass parameters. What method is used to implement multi-state parameter transfer, and what is the cause if no method is used; 6. Use a project to describe how to apply the design pattern. 7. Introduce your understanding of the design m

In today's MVC Framework, it seems that webwork2 has gradually become the mainstream, and the combination of webwork2 + springframework has become increasingly popular.
