6. Given: class Pet { public: virtual void eat() { cout eat(); } What is the result of compiling and running the above program? m. The program compiles and crashes when it runs. i. The program compiles and runs, printing "Pet::eat" j. The program compiles and runs, printing "Cat::eat" The program compiles and runs to completion without printing anything. n. o. None of the above. k. The program fails to compile because the method eat is not marked virtual in Cat. I. The program fails to compile for some other reason.

PROGRAMMING LANGUAGE: C++ SUBJECT: OOP Task: Suppose you have a class Rectangle with data members width and height. The public member functions of class Rectangle are as follows: setValues(int w, int h); // to set values of width and height of objects of Rectangle class int Area();// to find area of an object of rectangle class biggerRectangle(Rectangle A, Rectangle B); prints the rectangle details which is bigger. Sample Code for passing object to a function is given below: #include <iostream> using namespace std; class CRectangle { int width, height; public: void set_values (int, int); int area () {return (width * height);} void copyData(CRectangle rect); }; void CRectangle::copyData(CRectangle rect) { width=rect.width; height=rect.height; cout<<"width of c = "<<width<<", height of c= "<<height<<endl; } void CRectangle::set_values (int a, int b) { width = a; height = b; } int main () { CRectangle a,b,c;…
