C,C++ Questions 1. Base class has some virtual method and derived class has a method with the same name. If we initialize the base class pointer with derived object,. calling of that virtual method will result in which method being called? a. Base method b. Derived method.. Ans. b 2. For the following C program #define AREA(x)(3.14*x*x) main() {float r1=6.25,r2=2.5,a a=AREA(r1) printf(" Area of the circle is f", a) a=AREA(r2) printf(" Area of the circle is f", a) } What is the output? Ans. Area of the circle is 122.656250 Area of the circle is 19.625000 3. What do the following statements indicate.
