I have question about constructors,

If i have

Code:
Class A {
  private:
     int x;
     int y;
}

Class B : public A {
  private:
     int x;
     int y;
     int z;
}
Is there a way when I code the constructors I can leave the parent constructor and just do this->y = y; and since Class B calls the parent class, x,y would just be reduntent. This is similar to the command SUPER in JAVA. Just wondering. Thanks.
