A binder is a process in which a program itself is associated with one another. According to the different stages of the series, it can be divided into two kinds: static-linked and dynamic-linked.Static-linked SeriesStatic linking is the process of

1. Virtual destructor:A constructor cannot be a virtual function. When you create a derived class object, you must derive from the classThe root of the hierarchy begins, calling the constructor of the base class one by one along the inheritance

 In C + +, memory is divided into 5 extents, namely heap, stack, free storage, global/static storage, and constant storage.Stacks, which are the stores of variables that are allocated by the compiler when needed, and automatically purged when not

TemplateTemplates parameterize The type of data that a function or class is going to handle, acting as a parameter polymorphismSex, called the genus.The template is used to express the same logical structure, but data of a specific data element type

Memory allocation methodThere are three ways to allocate memory:(1) Allocation from static storage area;memory is allocated when the program is compiled, and the entire runtime of the program is present, for example, global variables, static

IStream & IStream:: Get (char *, int, char = ' \ n ');IStream & IStream:: Getline (char *, int, char = ' \ n ');Function: Extracts the specified number of characters from the text and adds a null character at the end of the string arrayWhere the

Delegates and events are generally used together, and events are special delegates, and the differences between events and delegates are:1. Delegates can use ' = ' to assign values and events cannot be2. Delegates can be called outside the class
