C#

Determine the output produced by the following C# code that uses struct and class definitions:

public struct S {

public int v;

public S(int a)

{ v = a; }

}

public class C {

public int v;

public C(int a)

{ v = a; }

}

S s1 = new S(1);

S s2 = new S(2);

Console.WriteLine("{0} {1}", s1.v, s2.v);

s2 = s1;

s1.v = 3;

Console.WriteLine("{0} {1}", s1.v, s2.v);

C c1 = new C(1);

C c2 = new C(2);

Console.WriteLine("{0} {1}", c1.v, c2.v);

c2= c1;

c1.v = 3;

Console.WriteLine("{0} {1}", c1.v, c2.v);
