What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
class A {
public:
int x;
A() { x=0;}
};
class B : protected A {
public:
int y;
using A::x;
B(int y) {this?>y = y;}
void Print() { cout << x << y; }
};
int main () {
B b(5);
b.Print();
return 0;
}
A.It prints: 05
B.It prints: 0
C.It prints: 5
D.It prints: 15

Which code, inserted at line 12, generates the output "5b"?
#include <iostream>
using namespace std;
namespace myNamespace1
{
int var = 5;
}
namespace myNamespace2
{
char var = 'b';
}
int main () {
//insert code here
return 0;
}
A.cout << myNamespace1::var << var;
B.cout << var << var;
C.cout << myNamespace1::var << myNamespace2::var;
D.None of these

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

}
int main (int argc, const char * argv[])
{
int i=0;
myFunction(i);
cout<<y<<" "<<x;
}
A.It prints: 0 5
