This chapter mainly refers to the knowledge of resource management, the most commonly used resources in C + + programs is the dynamic allocation of memory, but memory is only one of the many resources that must be managed, other common resources are

The Random class constructor1) random random = new random (); //Parameterless constructor uses the system clock to generate its seed valueHowever, the range of system clock values is limited , so in small-scale calculations, it may not be possible

sometimes, a base class is not associated with a specific thing, but rather an abstract concept that provides a common interface for its derived classes. For this reason, the concept of abstract class is introduced in C # . Note:C + + programmers

C ++ smart pointerIntroduction to C ++ smart pointer Many powerful functions of C ++ rely on pointers for implementation. However, pointers are the most error-prone. The most error-prone point is that when an object has been released, the pointer is
