A derived class inherits the ______of its base class.
Write the declaration for class \(B\). The class's members should be \(\bullet\) \(\mathrm{m},\) an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B. \(\bullet\) \(\mathrm{n},\) an integer. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class B. \(\bullet\) setM, getM, setN, and getN. These are the set and get functions for the member variables m and n. These functions should be accessible to code outside the class. \(\bullet\) calc, a public virtual member function that returns the value of m times n. Next write the declaration for class \(\mathrm{D}\), which is derived from class \(\mathrm{B}\). The class's members should be \(\bullet\) \(\mathrm{q},\) a float. This variable should not be accessible to code outside the class but should be accessible to member functions in any class derived from class \(\mathrm{D}\) \(\bullet\) \(\mathrm{r},\) a float. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class D. \(\bullet\) setQ, getQ, setR, and getR. These are the set and get functions for the member variables \(q\) and \(r .\) These functions should be accessible to code outside the class. \(\bullet\) calc, a public member function that overrides the base class calc function. This function should return the value of q times \(r\)
True or False The base class's access specification affects the way the derived class inherits members of the base class.
