Q1:

What will be the output of the following program?

#include<iostream.h> 
class A
{
    public:
    void AptitudeFunction(void)
    {
        cout<< 'Class A' << endl;
    }
};
class B: public A
{
    public:
    void AptitudeFunction(void)
    {
        cout<< 'Class B' << endl;
    } 
};
class C : public B
{
    public:
    void AptitudeFunction(void)
    {
        cout<< 'Class C' << endl;
    } 
};
int main()
{
    A *ptr;
    B objB;
    ptr = &objB;
    ptr = new C();
    ptr->AptitudeFunction();
    return 0; 
}
