using namespace std;

class A
{
	static int	m_count;					//声明静态数据成员
public:

	void showcount( )						//显示静态数据成员m_count的值
	{
		cout << m_count <<',';  
	}
};

int A::m_count = 0;						//静态数据成员初始化

int main( )
{
	A	a,b;
	a.showcount( );
	b.showcount( );
	
	a.setcount(32);
	a.showcount( );
	b.showcount( );
	
	b.setcount(10);
	a.showcount( );
