Suppose a Generic class called SortObjects is to be made capable of sorting objects of any type (Integer, Single, Byte etc.). Which of the following programming constructs should be used to implement the comparision function?

1. Delegates are not type-safe.
2. Delegate is a user-defined type.
3. Only one method can be bound with one delegate object.
4. Delegates can be used to implement callback notification.
5. Delegates permit execution of a method on a secondary thread in an asynchronous manner.

class Sample
{
    public int MyFun(int i)
    {
        Console.WriteLine("Welcome to CuriousTab.com !" );
        return 0;
    }
}

delegate void del(int i);
Sample s = new Sample();
deld = new del(ref s.MyFun);
d(10);

delegate int del(int i);
Sample s = new Sample(.);
del = new delegate(ref MyFun);
del(10);

Sample s = new Sample();
delegate void del = new delegate(ref MyFun);
del(10);

delegate int del(int i);
del d;
Sample s = new Sample();
d = new del(ref s.MyFun);
d(10);

class Sample
{
    public int func(int i, Single j)
    {
        /* Add code here. */
    }
}

1. Stack
2. Tree
3. SortedDictionary
4. SortedArray

public class TestCuriousTab
{
    public void TestSub<M> (M arg)
    {
        Console.Write(arg);
    }
}
class MyProgram
{
    static void Main(string[] args)
    {
        TestCuriousTab tab = new TestCuriousTab();
        tab.TestSub("CuriousTab ");
        tab.TestSub(4.2f);
    }
}

public class Generic<T>
{
    public T Field; 
    public void TestSub()
    {
        T i = Field + 1;
    }
}
class MyProgram
{
    static void Main(string[] args)
    {
        Generic<int> gen = new Generic<int>();
        gen.TestSub();
    }
}
