Which of the following statements are correct about static functions?

1. Static functions can access only static data.
2. Static functions cannot call instance functions.
3. It is necessary to initialize static data.
4. Instance functions can call static functions and access static data.
5. this reference is passed to static functions.

1. Constructors cannot be overloaded.
2. Constructors always have the name same as the name of the class.
3. Constructors are never called explicitly.
4. Constructors never return any value.
5. Constructors allocate space for the object in memory.

int[ , ] intMyArr = {{7, 1, 3}, {2, 9, 6}};

1. intMyArr represents rectangular array of 2 rows and 3 columns.
2. intMyArr.GetUpperBound(1) will yield 2.
3. intMyArr.Length will yield 24.
4. intMyArr represents 1-D array of 5 integers.
5. intMyArr.GetUpperBound(0) will yield 2.

   int[][][] intMyArr = new int[2][][];

    int[][]a = new int[2][];
    a[0] = new int[4]{6, 1 ,4, 3};
    a[1] = new int[3]{9, 2, 7}; 
    foreach (int[ ] i in a)
    {
        /* Add loop here */
        Console.Write(j + " ");
        Console.WriteLine(); 
    }

1. int[ , ] a;
   a = new int[2, 3]{{7, 1, 3},{2, 9, 6}};

2. int[ , ] a;
   a = new int[2, 3]{};

3. int[ , ] a = {{7, 1, 3}, {2, 9,6 }};

4. int[ , ] a;
   a = new int[1, 2];

5. int[ , ] a;
   a = new int[1, 2]{{7, 1, 3}, {2, 9, 6}};

1. int[] a = {25, 30, 40, 5};

2. int[] a;
   a = new int[3];
   a[0] = 25;
   a[1] = 30;
   a[2] = 40;
   a[3] = 5;

3. int[] a;
   a = new int{25, 30, 40, 5};

4. int[] a;
   a = new int[4]{25, 30, 40, 5};

5. int[] a;
   a = new int[4];
   a[0] = 25;
   a[1] = 30;
   a[2] = 40;
   a[3] = 5;
