class member

From:http://www.cnblogs.com/shijingxiang/articles/5389294.htmlRecently, the thread pool needs to be encapsulated into a C + + class named ThreadPool. Call Pthread_create in the member function Exec_task of the class to start the thread execution

Review: Definition of common function pointers1 Int(*PFI )() Question:Suppose there are the following classes: 1 Class Screen 2 { 3 Public : 4 Int Height (){ Return _ Height ;} 5 Int Width (){ Return _ Width ;} 6 // .

I used to think about how to call windows APIs such as wndclass and createthread in the class and how to use the member function address when passing in the function parameter address. For research, I wrote an example code: #include #include using

This is often the case when writing a program: You need to count the number of all object instances of a class. A simple method is to use a global variable, but its disadvantages are also obvious. Using static members can solve this problem well.

The following table provides an overview of the kinds of Members a class can contain.   Member Description Constants Constant values associated with the class Fields Variables of the class Methods

Generally, for standard C ++, the concept of member attributes does not exist. In the past, we used GetXXX/SetXXX to access or retrieve data, and we did not feel any inconvenience. However, after we use a language like C #, we always feel that the C

First, let's take a look at what I have referenced online: "The pointer format to the data member is as follows: :*   The pointer format to a member function is as follows: (:* ) ()For example, there is a Class: Class{Public:Int fun (int B)

There are three methods: 1.In this case, the thread function is declared as static, for example:Class crealtimetask{Public:Static uint taskmain (lpvoid PARAM );Bool starttask ();};For the member functions defined in the class, VC will impose a this

Class is better not to own fstream members: The opening, closing, and other operations of file objects are prone to Imperceptible operation failures due to various environmental changes in the runtime. This makes the test difficult.   Therefore,

The derived class does not have access permission to the private member of its base class, and does not have access permission to the protected member of the base class object) private and protected members have access permissions. Because c ++ has

The pointers in C language are flexible and convenient, but also error-prone. Many beginners of C language, and even the old birds of C language, are easily planted under the pointer of C language. But it is undeniable that the pointer position in

Here is a small example to illustrate how member functions are called in c ++. # Include Using namespace std; class Test {public: void funcMember () {cout (Const_cast (This); // int * ptr = (int *) (const_cast (This);

The Code is as follows:[Java]Package com. test; Import java. lang. reflect. Field;Import java. lang. reflect. Modifier; Public class Test_5 {Public static final int a = 111;Public static final int B = 222;Public static final int c = 333;Public

# Include # Include # Include Using namespace STD; Class {Public:Int fun (int B){Return a * C + B;}A (int I){A = I;}Int C;PRIVATE:Int;}; Int main (){Int A: * Pc = & A: C;INT (A: * pfun) (INT) = A: fun;A A (10 );A. * Pc = 8;Cout A * P = &;P-> * Pc =

# Include Class Object {}; typedef int (Object: * sayfunc) (const char *); Class A: Public object {public: int say (const char * MSG) {STD: cout fun = fun; This-> Target = target ;}~ Controller () {} void dofun (const char * MSG) {// (Target-> *

from C ++ common knowledge # Include using namespace STD; extern void fi (INT); extern void Fl (long); extern void FC (char); Class Foo {public: Foo () {}; virtual ~ Foo () {}; static void do_foo (int I) {cout INT:" * pimc * pfab) () INT:" *

  The access modifier is used to specify the accessibility of class members. The C # access modifiers include private, protected, public, and internal. Private declares Private Members. Private Data members can only be used and modified by

I was reading "C ++ meditation" just now and had doubts about the following code: Class vehicelsurrogate { Public: //.... vehiclesurrogate (const vehicelsurrogate &); //.... PRIVATE: vehicle * VP; }; vehicelsurrogate: vehicelsurrogate (const
