Document comment This type of annotation uses.. Net has defined Xml labels for marking. This class of annotations should be used to declare interfaces, classes, methods, attributes, and fields so that code documents can be directly generated after the code is complete, let others better understand the code implementation and interfaces.

In many programming languages, call-by-value and call-by-reference methods are used to call functions ). When a parameter is passed by value, a copy of the parameter value is generated and passed to the called function. The change of the copy does not affect the original variable value of the caller. This prevents unexpected side effects from affecting development correctness, reliable system. One disadvantage of calling by value is that if a large data item is passed, copying the data may take

Consider the following code:1 void Inc (int a) {a++;}2 int n = 0;3 Bind (inc, N) ();After calling the function object returned by BIND, n is still equal to 0. This is due to bind, when a copy of n is passed in. If you need to pass in a reference to n, you can use the ref or CREF function, such as:1 Bind (inc, ref (n)) (); n is now equal to 1.2. The first parameter of BIND is a function object and cannot be re

In the form of a member function pointer to PTR with bind binding parameter, the first bound parameter of BIND is the caller of the member function, followed by the parameter binding method of the member function. For example, bind (PTR,A,B,C) will call A.*ptr (B,C). When a _n constant is u
