Get started for freeWrite the first line of the declaration for a Soundsystem class. Use multiple inheritance to base the class on the CDplayer class, the Tuner class, and the CassettePlayer class. Use public base class access in all cases.
True or False The base class's access specification affects the way base class member functions may access base class member variables.
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 \(r\)
What base class is named in the line below? class Pet : public Dog
______________ is when member functions in a class hierarchy behave differently, depending upon which object performs the call.
