Accessing a base class member in derived class

Question

I have a simple class as below

class A {
        protected:
        int x;
        };

class B:public A
        {
        public:
        int y;
      void s         


        

Answer 1

You can just refer to it simply as x in class B

For example:

class B : public A
{
public:
    ...

    void setx(int d)
    {
        x=d;
    }
};
