{
s.x=10;
s.i=0;
cout << s.i << " " << s.x;
}

~First() { delete s;}

void Print(){ cout<<*s;}

};

int main()

{

First FirstObject;
FirstObject.~First();

}

What happens when you attempt to compile and run the following code?

#include <iostream>

using namespace std;

{

float b;

b = f(20,10);

cout << b;

return 0;

}

int f(int a, int b)

{

return a/b;

}

What will happen when you attempt to compile and run the following code?

{

string s="Hello";

cout << fun(s, " World");

return 0;

}

string fun(string s1, string s2)

{

return s1+s2;

}
