Calculate the ThinkPHP nested loop by 40 minutes to print out the list of parent classes and child classes. Hello, I have been learning the thinkPHP framework recently. I want to print out a data list cyclically on the template page, the format is: first, the parent class category name, then print the corresponding subclass list, then print another parent class name, and then print the corresponding subclas

Balon vernacular msdn: export C ++ classes from common DLL (2)-a closer look at the underlying mechanism of exporting C ++ classes in the previous article, we introduced how to export C ++ classes from a DLL and how to selectively export C ++ class members. So what is the underlying mechanism of the entire system? In what ways can we use the class exported from o

For Nested classes, see this article. For more information about internal classes, see this article. It is worth noting that Static internal classes cannot access external non-static members (restricted by the non-static member access conventions of Java static members) The internal class. Class file name format is as follows: If it is a stati

The relationship between classes (objects) 1, inheritance relationships C + + has multiple inheritance mechanisms. If you have a member variable of the same name in the two parent class of a class, it is more difficult to handle. 2. Realization relationship (class and Interface, polymorphic) 3, association relationship is the weakest relationship. An association relationship is an object in a class that has another class in its method. Life Example:

1. What if someone asks you if the interface in Java can be new? I think the answer should be yes, when implementing an anonymous inner class.http://blog.csdn.net/cntanghai/article/details/60944812. If someone asks you if the class can be modified by private, I think the answer is yes, one of the benefits of the inner class.1. internal classes can be very good to implement the hiddenThe generic non-intrinsic class is not allowed to have private and pr

1. First determine whether the project->build automatically is selected;2. After the first step, test to see if it compiles, and if not, compile manually:3, go to the Clean dialog, select Clean Projects selected below, then select OK4, the third step after the completion of the recompile test, if still cannot compile, that is the project set up a problem. Select Item Right-click->properties->java Build path->sourceSet the default output folder to Sevlettest/webcontent/web-inf/

About the documents and views under MFC and the access to the framework, these issues have been commonplace, but I think there is no detailed description, special Not for the poor English people, I looked at some blog, summed up a bit! I hope it helps people like me!One:1: Because for the SDI program, the main frame window is the Document box window (if this also do not know, it is necessary to look at MFC under the form of a single document principle).The following is about a single document.Ex

For example, there are two classes. Father is the parent class, and son class inherits from father. Father F1 = new son (); // This is called upcasting (upward transformation) // Now F1 references a son object Son S1 = (son) F1; // This is called downcasting (downward transformation) // At present, F1 still points to the son object 2nd examples: Father F2 = new father (); Son S2 = (son) F2; // error, subclass reference cannot point to parent cl

Two classes are used in the project, one of which is nested in the other, the external class is named couterclass, And the nested class is named cinnerclass. In a nested class, a member function needs to use a member function of an external class. Class couterclass To call a function of an external class, you must first obtain the pointer of an external class. Therefore, you must define a function in the nested class: getouterclass () to return the
