class MyBag{
public:
MyBag(string br, string cr):brand(br), color(cr){++count; }
static int GetCount(){return count; }
private:
string brand, color;
static int count;
};
int MyBag::count=0;
int main(){
MyBag one("CityLife", "Gray");
cout＜＜one.GetCount();
MyBag*ptr=new MyBag("Coach", "Black");
cout＜＜MyBag::GetCount();
return 0;
