C++类中static不计算入sizeof

class MyParam{  public:    int a;    static int b;    int c;    static int y;    static int z;};

sizeof(MyParam) = 8

int MyParam::b = 10;int MyParam::z = 10;int main(){  MyParam p;  MyParam dest;  p.a = 10;  p.b = 2;  p.c = 4;  memcpy(&dest, &p, sizeof(MyParam));  printf("sizeof(MyParam)=%d\n", sizeof(MyParam));  printf("%d %d %d\n", p.a, p.b, p.c);  printf("%d %d %d\n", dest.a, dest.b, dest.c);}
