PointerBefore learning pointers, you should first understand something:What is memory?From the hardware form, memory is a strip of physical equipment, functionally speaking, memory is a data warehouse, the program is loaded into memory before

C++11 also adds a number of useful features, such as:1. Delegate ConstructorsIf a class contains many constructors, these constructors have some duplication, such as:Class A{public: A () {}; A (int a) { a_ = A; }; A (int a, int b)
