function on the blog to see an article "FxCop constructorsshouldnotcallbaseclassvirtualmethods norms," the original: http://blog.csdn.net/xamcsdn2/ Archive/2004/08/11/71766.aspx Quite interested in writing a piece of code research (the estimate is still not a study, just explore it) a bit. The code is as follows. Using System; Namespace Test_console { ??? Class BaseClass ??? { ??????? public int count = 0; ??????? Public BaseClass () ??????? { ??

class function, the C + + compiler does not control whether the class is empty, but instead passes the address of the class as the this pointer to the function.A->print (), it is equivalent to print (A) in the compilerThere are cases where member variables are not used in print, so it is natural to run correctly.Then look at the assembly code to get a better understanding of it. The following is the assembly code within the People class. 21 void e

I met a very strange question yesterday.I used Easyui to make a website, which has a page and a B page, I through the Easyui window function, a page popped a B page, in the B page, I used an external JS function C, I in the B page I also quoted this JS file, But every time the JS code goes to function C, it is prompt "Microsoft JScript

See stroustrup's answer (http://www.research.att.com /~ BS/bs_faq2.html # vcall) Although calling a virtual member function in constructor is not a very common technique, studying it can deepen the understanding of the virtual function mechanism and object construction process. This problem is also different from t

1. When a constructor is called in a subclass, its parent constructor is definitely called first. If there is a virtual function in the parent class constructor, and there is a subclass, it must execute the virtual function in the parent class, and the member variable in the subclass is not initialized, so the correspo
