What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
class A
{
public:
virtual void Print(){ cout<<"A";}
};
class B:public A
{
public:
void Print(){ cout<< "B";}
};
int main()
{
A *obj;
A ob1;
obj = &ob1;
obj>Print();
B ob2;
obj = &ob2;
obj>Print();
}

What happens when you attempt to compile and run the following code?
#include <iostream>
#include <string>
using namespace std;
class SampleClass
{
string *s;
public:
SampleClass() { s = new string("Text");}
SampleClass(string s) { this->s = new string(s);}
~SampleClass() { delete s;}
void Print(){ cout<<*s;}
};
int main()
{
SampleClass *obj;
obj = new SampleClass("Test");
obj->Print();
}

What is the output of the program?
#include <iostream>
#include <string>
using namespace std;
class First
{
string name;
public:
First() {
name = "Alan";
}
void Print(){
cout << name;
}
};
int main()
{
First ob1,*ob2;
ob2 = new First();
ob1.Print(); ob2->Print(); }

What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
int main(){
int i = 1;
if (--i==1) {
cout << i;
} else {
cout << i-1;
}
return 0;
}

If there is one, point out an error in the program
#include <iostream>
using namespace std;
int main() {
int c = 'a';
switch(i)
{
case '2':
cout<<"OK";
case '1':
cout<<"Error";
default:
break;
}
return 0;
}
