P25 (2.2.8 Initialization of Contants Static Members)
*******************************************************************
It is now possible to initialize integral constant static members inside the class structure.
This is useful when the constants is used in the class structure after the initialization.
(对于当这个常量会在初始化后要使用的情况，这样做会比较有效)

For example ===>
    class MyClass{
        static const int NUM = 100;
        int elements[NUM];
        ...
    };

Note that you still have to to define space for a constant static member that is initialized within a class definition:
  const int MyClass::NUM;         //no initialization here

#pragma warning(disable:4530)
#include <iostream>

using namespace std;

class A
{
public:
A(){
  for(int i=0; i<SIZE; i++)
   num[i] = i;
}
void print(){
  for(int i=0; i<SIZE; i++)
   cout<<num[i]<<" "<<endl;
}
private:
static const SIZE = 10;
//注意：由于SIZE作为一个const常量，所以必须在首次定义的时候就给它赋值。
int num[SIZE];
};

const int A::SIZE;
//注意：由于SIZE作为一个类的静态成员，应该在类体外部定义（以取得和全局变量类似的效用）
int main()
{
A a;
a.print();
return 0;
}
