Which of the following statements about inheriting base class constructors is false?
a. To inherit a base class’s constructors, you write the following line of code in the derived class definition (BaseClass is the base class’s name): using BaseClass::BaseClass; b. If an inherited base-class constructor has default arguments, the line of code in Part (a) causes the compiler to generate a derived-class constructor with the same default arguments. c.
