What will happen when the following code is compiled and executed?
#include<iostream>
using namespace std;
class myclass
{
private:
int number;
public:
myclass()
{
number = 2;
}
int &a()
{
return number;
}
};
int main()
{
myclass m1,m2;
m1.a() = 5;
m2.a() = m1.a();
cout << m2.a();
return 0;
}

Consider the following code: #include using namespace std; class A { public: A() { cout << 'Constructor of A\n'; }; ~A() { cout << 'Destructor of A\n'; }; }; class B { public: B() { cout << 'Constructor of B\n'; }; ~B() { cout << 'Destructor of B\n'; }; }; class C { public: A objA; B objB; }; int main() { C *pC; pC = new C(); delete pC; return 0; } What will be the printed output?

Answer the question that follows. class Person { public: Person(); virtual ~Person(); }; class Student : public Person { public: Student(); ~Student(); }; main() { Person *p = new Student(); delete p; } Why is the keyword 'virtual' added before the Person destructor?

Answer the question that follows. class Outer { public: class Inner { int Count; public: Inner(){}; }; }; int main() { Inner innerObject; Outer outObject; return 0; } What will be the result when the above code is compiled?

Output of the code? class Shape { public: virtual void draw() = 0; }; class Rectangle: public Shape { public: void draw() { // Code to draw rectangle } //Some more member functions..... }; class Circle : public Shape { public: void draw() { // Code to draw circle } //Some more member functions..... }; int main() { Shape objShape; objShape.draw(); } What happens if the above program is compiled and executed?
