{
    int i;
    Single j;
    double k;
    public Sample (int ii, Single jj, double kk)
    {
        i = ii;

3. Which of the following is the correct way to define the constructor(s) of the Sample class if we are to create objects as per the C#.NET code snippet given below?
```
Sample s1 = new Sample(); 
Sample s2 = new Sample(9, 5.6f);
```
Options

public Sample()
{
    i = 0; 
    j = 0.0f;
}
public Sample (int ii, Single jj)
{
    i = ii;
    j = jj;
}

public Sample (Optional int ii = 0, Optional Single jj = 0.0f)
{
    i = ii;
    j = jj;
}

public Sample (int ii, Single jj)
{
    i = ii;
    j = jj;
}

D.
```
Sample s;
```
E.
```
s = new Sample();
```

Correct Answer:

public Sample()
{
    i = 0; 
    j = 0.0f;
}
public Sample (int ii, Single jj)
{
    i = ii;
    j = jj;
}

5. What will be the output of the C#.NET code snippet given below?

namespace CuriousTabConsoleApplication
{ 
    class Sample
    { 
        static Sample()
        { 
            Console.Write("Sample class ");
        }
        public static void CuriousTab1()
        { 
            Console.Write("CuriousTab1 method ");
        } 
    } 
    class MyProgram
    { 
        static void Main(string[ ] args)
        { 
            Sample.CuriousTab1();
        } 
    }

8. Which of the following statements are correct about the C#.NET code snippet given below?

class Sample
{
    static int i;
    int j;
    public void proc1()
    {
        i = 11; 
        j = 22;

10. Which of the following statements is correct about the C#.NET code snippet given below?

namespace CuriousTabConsoleApplication
{ 
    class Sample
    { 
        public int func()
        {
            return 1;
        } 
        public Single func()
        { 
            return 2.4f ;
        } 
    } 
    class Program
    { 
        static void Main(string[ ] args)
        {
            Sample s1 = new Sample(); 
            int i;
            i = s1.func(); 
            Single j; 
            j = s1.func(); 
        } 
    } 
}

Options
A. func() is a valid overloaded function.
B. Overloading works only in case of subroutines and not in case of functions.
C. func() cannot be considered overloaded because: return value cannot be used to distinguish between two overloaded functions.
D. The call to i = s1.func() will assign 1 to i.
E. The call j = s1.func() will assign 2.4 to j.
