switch (c)
{
case 1:
throw 20;
case 2:
throw 5.2f;
case 3:
throw 'a';
default:
cout<<"No exception";

fun(++n);
cout << n;
}
}
What happens when you attempt to compile and run the following code?

{
BaseC *o = new BaseC(5);
o?>Print();

int main()
{
A ob1;

A *obj;
obj = &ob1;
obj?>Print();
obj = &ob2;
obj?>Print();
obj = &ob3;
obj?>Print();
}
What happens when you attempt to compile and run the following code?
