1. What will be the output of the following program? #include<iostream.h> class BixBase { public: int x, y; BixBase(int xx = 0, int yy = 5) { x = ++xx; y = --yy; } void Display() { cout<< --y; } ~BixBase(){} }; class BixDerived : public BixBase { public: void Increment() { y++; } void Display() { cout<< --y; } }; int main() { BixDerived objBix; objBix.Increment(); objBix.Display(); return 0; }
