(6) The following question is referring to the CH source code in Figure Q2(b). #include using namespace std; class Box private: float length; float height; float width; public: Box(); void setValues (float, float, float); float getVolume (); }; void Box:: setValues (float 1, float h, float w) length = 1; height = h; width = w; 1 float Box::getVolume () return (length"height*width); } int main() Box cubic; return 0; Figure Q2(b) 16 (1) Write a function definition for constructor to initialize all private member variables to 0.0. [5 marks] (ii) In main function, construct a CH code to call setValues() member function and set the private member variables as following, length = 2.4 height=6.8 width=10.12 [4 marks] (iii) In main function, write a C++ code to display the volume of cubic object by calling the getVolume () member function. Your output console should display as per Figure Q2(b)(iii). Volume is : 165.158 Process returned (exe) Press any key to continue. execution time : 0.070 s Figure Q2(b)(iii) [3 marks)
